Hdlook can be found here: http://www.brutman.com/hdlook.zip

It is a little rough around the edges.  Basically, it shows you what
your AT class machine thinks it has for hard drives.  The geometry of
the drives, as well as the locations of the table entries used to
describe the hard drives are displayed.

Don't run it under Windows - use a DOS boot disk.

I wrote it to try to understand how the Grid was assigning hard drive
values.  I don't own a Grid myself and having Shawn read output from
'debug' was a wee bit too slow, so I wrote this to dump out what I
needed instead.

From: Shawnerz
Subject: Re: [RuGRiD-Laptop] SUCCESS!!...kind of...

Charles,
My lack of real world programming experience come to
light here.  However, I have put some thought into how
a program could be laid out.  
A program like hdlook.exe could be run.  The values it
found for the hard drive could be stored in variables.

Every Sectors (per track) value in the drive table is
11h (17 decimal).  The Sectors value is the 2nd to
last byte of the table entry.  Each table entry is 16
bytes long.
One search method would be to look for a value of 11. 
Once an 11 is found, then jump 16 bytes.  Is this
value 11?  If not, it's not the start of the table. 
Search for the next value of 11.  Once the program
finds an 11, jump 16 bytes.  Is it 11?  If yes, then
jump another 16 bytes and see if the value is 11. 
(This time it's just to verify that the program has
actually found the table and the 11 was not a
coincidence).
Next, this program would update the table with the
variables from hdlook.
The text field would also have to be updated.  One way
to do this is to search for the hex equivilent of
"CP".  Once this is found, the program could prompt
the user to enter the drive type.
Once that has been entered, the program would have to
generate the odd and even files.  Then, it would have
to compute the 16 bit checksum of each file.  Then
modify the beginning part of each file to get the
checksum back to the original checksum value.
Then, of course, the program would have to store the
modified files to the files could be burned into new
(E)Proms.
That should take, what, 10, maybe 15 lines of code,
right?  ;-)  HA!

Charles,
I had logged off the computer and was about to go to
bed.  I started thinking, "fisheggs?  What did he mean
by fishegg hard drive?"
The answer came to me soon afterwards: fisheggs a.k.a
caviar, a.k.a Western Digital Caviar.
I never said I was the brightest bulb, but I do catch
on eventually... :)

Shawn,
    I also did a double take for about a minute when he said that
until I made the connection. However I discovered the physical
placement of the pin configuration on my "fishegg" drives are not
compatible with the Conner, therefore they won't fit onto the
connecting board with the floppy drive. I'll have to go searching for
another unit.

Thanks Charle and Shawn,

      As I noted, My WD caviar 280 did not have the correct
orientation of the pins to fit inside my 1530's, so I went looking at
my local computer junk store and I found two Conner CP30174E drives,
which both apparently work well. They're at 170 Mb capacity.
Physically they are configured to fit. Now all I need is the patch
you have come up with, please and thank you, whenever you finish
testing it out. I know a little about programming but not enough to
ctatch completely on to what you all are doing here, so when it's
finished, if you could take it through step by step, I'd be most
grateful.

Thanks, Mike,

    I downoaded the zip file for hdlook, but when I tried to extract
it, it asked for a password. Could you provdide that for me? I didn't
see it listed in your email or on your website.

Thanks,

Thanks, Mike

    "Password" worked just fine. I used the program to get the specs
on the Conner CP30174E. They are as follows:

        Intra Vec Location: 0000:0118
        Table location: F000:EFF5
        Maximum Cylinders: 903
        Maximum Heads: 8
        Write Pre Comp Cyliner: 65535
        Control Byte: 0
        Landing Zone Cylinder: 902
        Sectors Per Track: 46
        Total KiloBytes: 166152
        Total MegaBytes: 12.257812

   I know you only need three or four pieces of that info, but it's
all there just in case.

   As I suspected, my old HDD was dead when I tried on the machine
I'm using to test the drives. Its actually a CP 30104, and I know I
have different BIOS chips since it has to have a different table
defining the usable hard drives. They put them in when I upgraded the
unit to a plasma screen back in 1987. I still have the original BIOS
chips and old memory too as they sent those back when I received the
unit from GRID after the upgrade.

   The old HDD seems to want to start up because I can feel it
vibrate at first, but then after that it seems nothing happens. I
wonder if this is just a failure of the motor drive itself, or is
there something else going on. There is no clicking.

Sorry for the double post,guys,

But I just found a table for all the Conner Hard Drives. It lists all
their hard drive information avaiable. It's at the following address:

http://www.computerhope.com/hdconner.htm

That may actally give all the Data you would normally get from
hdlook, that would you needfor any hard drive.

Hope that helps.

Jeriddian:

If I remember correctly I had to bend the power connectors to one side, 
they are about 1/16 off.
But I could be wrong about the old WD drive (its been a few years, and I 
have professors cramming all sorts of new stuff into my head)

You will actually need lines 3 through 8.

At one time, we had a technician that worked for
Conner on the list.  The head may be stuck to the
platter.  I believe that's called "stiction."
Try twisting the drive as much as you can.  It is
supposed to help to free the head from the platter. 
Also, I've heard firmly hitting the drive on concrete
might help too.  I'm not recommending you take a
hammer to it on the concrete.  I'm just suggesting one
or two firm hits to free the head.

Lists like the above may be helpful, but don't believe
everything you read.  I would have never expected my
Conner CFS420A hard drive actually report as a CPS320.
 On the hard drive, there are two unaltered lables
from Conner Periphierials that say the drive is a
CFS420A.  However, when plugged into my desktop, the
drive reports as a CPS320.  That type of information
is not online.
Also, I have an old copy of the Hard Drive Bible. 
There are descrepancies between the printed
information in the book and the CD that came with the
book.

I started instructions on how to do this.  I'm about
2/3 of the way done, I've typed for about an hour, and
I've realised this process is very complex.  You need
access to a computer, be comfortable working with a
hex editor and EPROM programmer.  Depending on the
revision of your Grid motherboard, you may need to
desolder the BIOS EPROMs.  I have 4, 1520's.  2 of
them have the BIOS EPROMs in very low profile sockets.
 The other 2 have the EPROMs soldered into the
motherboard.

I'll finish the procedure on Sunday or Monday.  I'll
warn everyone now, that it's long and detailed.

I hope this helps,
-Shawn

Sorry about that, My name is Felipe (or just Phil will do).
Jeriddian's just my usual internet handle. I forgot that I was using
my FelipeGPorresMD@msn.com email site instead of the other.

Thanks for the info.

I appreciate it very much.

I'm sorry, Mike,but it's a typo. It's really this:

Total Megabytes: 162.257812

Somehow the "6" didn't get in there.

Subject: Another Layer of the Grid Onion: LBA

All,
I'm confused again.  I have a bunch of information,
but I can't make sense of it all.

1.  Hard Drive.  The CFS420 hard drive actually
reports as a CFA320 hard drive.  I did a quick search,
and the CFA320 is a SCSI drive.  This is probably not
important.

2.  The drive geometry of this drive is 665 cylinders,
16 heads and 63 sectors/track.  This computes to 343
MB.  
When this drive is fdisk-ed and formatted in the Grid,
it reports having 771 cylders, 8 heads, and 33
sectors/track.  hdlook.exe reports this same
information.  Fdisk now reports the size as 99 MB.

3.  If I take the drive that has been formatted in the
Grid and place it in my Pentium, its BIOS reports 1024
cylinders, 8 heads, and 33 sectors.  The Pentium BIOS
reports the CHS capacity as 138 MB and the Maximum LBA
Capacity as 343 MB.

4.  If I format the drive in the Pentium, I get the
full 340 MB size.  If I install DOS on the drive and
then return the drive to Grid, I get a "Non-System
Disk" error.
In other words, the Grid recognized the drive, but
can't read the information on the drive.

I don't understand why the Grid lists the size as 99
MB. The CHS information is 771 cylinders, 8 heads, and
33 sectors.  These values explain the 99 MB drive
size, but I cannot explain how the computer got those
values.  None of those values are in any table.

Why would drive report as having 771 cylinders on the
Grid, but 1024 cylinders in the Pentium?

Does this have to do with LBA mode?  I thought LBA
only applied to the way the information was indexed on
the drive.  I didn't think it made any difference to
the storage capacity.

-Shawn

You can't trust the drive geometry reported by a machine - it might be 
fudging things.

Old machines are limited to 16 heads and, 1024 cylinders and 63 
sectors.  This is because the areas in the BIOS that deal with these 
values only left 4 bits, 10 bits, and 6 bits to express those values.  
Add them up and you get 528MB.

Now if you had a drive that was bigger in some regard, you could lie 
about one of the parameters.  Most drives only have 2 or 4 platters, for 
a possible total of 8 heads.  If you have more than 1024 cylinders you 
could lie and say you had more heads and less cylinders, and still work 
with an old BIOS.  Of course anything that assumed the drive really was 
writing to where it said it was would be wrong, but as long as the drive 
lies consistently it would be ok.

Here is a good link that explains things in detail:

http://www.ata-atapi.com/hiwchs.htm


So some questions:

- What is the geometry of the drive, as written on the label or from the 
web?
- It's an IDE drive right?  SCSI and IDE are not interchangeable.

A 300 or 400MB drive should work seamlessly without LBA or extended INT 
13 tricks, unless it has a goofy number of cylinders or sectors per 
track.  If you format the drive in a modern machine, turn off the LBA 
and extended INT 13 translation, and let it use good old CHS 
addressing.  That will make it compatible with things like the Grid.

The Grid might be assuming 17 sectors per track.  If you have a drive 
that has more than than, too bad ..  it just becomes unused space.  You 
might be able to alter the drive table to use more than 17 sectors per 
track and be able to use the full capacity of the drive.

Thanks for the reply, Mike.
 The label on the drive says 665 Cylinders, 16 Heads,
and 63 Sector/Track.  That adds up to 343 MB.
The Pentium BIOS and hdlook (when run on the Pentium)
agree get the same value.
I understand the part about the "lying".  But, these
values don't exceed the number of bits so no lying is
needed.

It is an IDE drive.

If the Grid is limiting the drive to 17 sectors per
track, the numbers still don't add up.  It's close. 
99.386719 MB (as reported from hdlook) vs. 92.61056 MB
(computed using 17 sectors/track).

How is this 286 computer getting 771 cylinders, 8
heads, and 33 sectors per track from 665 cylinders, 16
heads, 63 sectors per track????

Jeriddian,
The chips are 27C128 in a 28 pin DIP package.  Several
places sell them.
www.jameco.com is where I got mine.  Newark
Electronics is another source but they have a 10 day
lead time. You can also find used ones on Ebay.  I've
purchased a few there as well.
It looks like these are getting difficult to find.  I
just checked with Digikey and Mouser and they have 
discontinued this part. :(

The EPROM programmers (or, burners) are a bit more
expensive.  They are about $250 to $300. I'm
"borrowing" one from my job.  When I started at my job
back in 2000, we were not doing anything with DIP
packages.  The programmer was sitting on a backroom
shelf until I "rescued" it.
I bought a Qualtec programmer from Ebay, but I have
damaged it.  I fed it 12 Volts AC instead of 12 Volts
DC and it hasn't recovered.
Here is one place: http://www.needhams.com/
Here is another one:

I hope this helps you out.

Sorry for the double post, Shawn.
    I wanted to ask. I searched and I am finding some outlets,
including the outlets for used ones on EBAY, so I should be picking

and 27C128-20. Does it make a difference which one I get? Thanks for

Phil,
I do not know.  The -15 means 15 mS (milli-seconds)
and the -20 means 20 mS.  It is an indication of how
quickly the data can be stored into the EPROM.  The
lower the number, the more quickly it can be
programmed.  I am using -15's and and I have not had
any problems.

One thing I forgot to add to the list of needed
equipment is a UV (ultra violet) light to erase the
EPROMs.  You will need this unless you plan to
continually use new EPROMs.
I have heard setting EPROMs in direct sunlight for 30
minutes will erase them too.  I have never tried it.

Also, if I'm successful I will offer everyone the
chance to burn chips.  I will do it at a to be
determined very inexpensive rate.  I don't want
someone going out and spending $500 to modify a single
286 computer.
I'm doing this project because I enjoy doing this. 
I'm not doing this for the money.  
Maybe I'm a masochist...  :)

From: "jeriddian"
Subject: Re:SUCcESS!!...kind of...

Shawn,
   Yeah, I kind of figured it was the speed of the chip that was
being indicated, although the speed of the chips I found for sale
were 120 ns, 150 ns, and 200 ns, so I suppose the numbers refer to
that. Anyway, I'm looking at picking some 15's. I've also been
getting a look at some of the erasers, too, since it looks like the
27C128 were not that popular a chip and are getting more scarce, so I
am probably going to have to get used ones. The 27C256's are more
popular and apparently less rare, and I have run across a procedure
where they can be substituted for the 27C128 by making sure the
starting address for readng the chip is at 4000H.

I remember from way back how EPROM's supposedly can be erased just by
exposure to the sun for half a minute, but I'm looking into getting
an eraser too. And like you, I'm not doing this for the money. I will
plan on burning the chips for my 1530's and getting them going and
then offer the service myself pretty much at cost to others.

Yahoo! Message number: 1528
Date: Wed, 28 Feb 2007 09:32:59 -0800 (PST)
From: Shawnerz
Subject: Re: [RuGRiD-Laptop] Re:SUCcESS!!...kind of...

Phil,
You know, when I first wrote my response, I wrote it
as 150 mS and 120 mS.  But, I looked it over and
thought, "That seems like a very long time.  12 and 15
mS sounds more like it."
I was too lazy to check the data sheet so, I changed
it.
So, I guess I was wrong.  I should have went with my
first instinct...

I have 1 27C256 chip but I've never tried to see if it
will work in the Grid.  Without actually trying
anything, it seems that you would want to use lower
16K and not the upper 16K.
The 27C128 users addresses $0000 to $3FFF.  The 27C256
uses $0000 to $7FFF.  It seems you would want to keep
the starting range at $0000 so all of the data in the
$0000 to $3FFF range on the -256.
One day, when I get even more free time, I'll try it
out...

Take care,
-Shawn

Subject: Re:SUCcESS!!...kind of...

Shawn,

     No prob. The 150 ns chips should do fine. As to programming the
27C256 chips for the 27C128 job, I'll give you the following address:

www.tunercat.com/tnr_desc/eprom_pin/eprom_pins.html

That's where I read about having to program the back end of the chip
to do the job correctly. John Gantt turned me on to an auction for a
burner, but I lost that auction, so I'll have to buy another one,
but I think I've already found one anyway.

I'm out of town right now, but when I get back next week, I should
have the unit and I'll see what my 1530 chips look like and
determine if they are 27C128's after all, and see what's on them.

Subject: Larger Hard Drives in a 1520 (Success...finally)

All,
I was able to get the my Grid 1520 to boot from a 340
MB hard drive AND recognize all 340 MB!! 

The short version of the story is the drive parameters
of the drive that you want to boot from, has to be the
2nd entry in the drive table.

The long version of the story:

Note: I am going to refer to the hard drive that you
wish to install in your Grid as the "new" hard drive. 
The "default" hard drive is one of the Conner hard
drives that the Grid recognizes by default.
 
The hard drive parameter table has 23 entries for 23
different hard drive types.  According to hdlook.exe,
HD1 gets loaded with the first table entry and HD0
gets the second table entry.  I would have expected
HD0 to be the first and HD1 to be the second, but that
is not the case.

I made a couple of assumptions.  One of them turned
out to be wrong.  First, I thought as long as the new
hard drive parameters of your new hard drive is in the
table, anywhere in the table, the Grid will recognize
all of it AND boot from it.
The reality is if the new hard drive parameters are in
the table, the Grid can boot from it, but it will not
"see" all of the drive space.  The new hard drive
parameters have to be the 2nd table entry.

When I first entered the parameters for my 340 MB hard
drive, I diliberatly did not use the first two table
entries.  The first table entry is for a default 10 MB
drive.  The second entry of for the CP3024 20 MB
drive.  I thought I was being safe by not using those
two table entries.  I was wrong.
I did some testing, and I got some unexpected results.
 I couldn't wait until tonight to get some time to
test out another idea.  It worked!

It is possible that the new hard drive parameters
could be entered into the first table entry.  I might
try that this weekend if I get some time.  Right now,
I'm just very happy to have MS-DOS 6.22 installed on
my Grid and have 335,962,112 bytes free!
-Shawn

Phil, Shawn:
The extention number on the ROM package is access time (has nothing to 
do with programing)
15 = 150 nS, 20 = 200 nS and so on.
For the 1520 you will need to have an access time of 400nS  or better 
(that is a 40 or less)
For the 1530 you will need 250nS or better (less than 25 on the package)

Subject: Reprogramming 1520 BIOS For Larger Hard Drives

This procedure is written for the Grid 1520 computer. 
It will probably work with any 15XX flavor of Grid. 
However, the address locations will be different.

This procedure is to give a step-by-step instruction
showing how to enable the Grid 1520 to see just about
any hard drive up to XXX MB.

At the time of this writing (March 2007), 3 different
BIOS versions for the 1520 have been identified.  
"Revision 1" has checksums DE00 (Even) and 0B00 (Odd).
 
"Revision 2" has checksums 7A00 (Even) and 2F00 (Odd).
 
"Revision 3" has checksums 437C (Even) and DD00 (Odd).


Materials needed:
Grid 1520 computer
Standard PC desktop
Hex editor
EPROM programmer (with associated cables)
Blank 27C128 EPROMs (minimum of 2)
Floppy disk with hdlook.exe
Phillips and flat blade (or slotted) screwdrivers

Optional Equipment:
UV EPROM eraser
Soldering iron and the ability to remove and replace
28 pin DIP ICs.
IC Puller

Overall notes:
I will start by saying this is not an easy process. 
Depending on the version of your Grid motherboard, you
may need very good soldering skills to remove the
original EPROMs.  The original EPROMs may be soldered
to the motherboard.  I have 4, 1520's.  2 of the
motherboards have the BIOS (E)PROM's soldered, and 2
have the chips in low profile sockets.  

This process assumes you have a hex editor installed
on the PC.  You also need to be familiar working with
your hex editor.  You will have to computer checksums,
merge files, search, edit, save and split files.  I
used WinHex (availble at
www.winhex.com/winhex/index-m.html)

Hdlook.exe is a program written by Mike Brutman and is
available here: www.brutman.com/hdlook.zip 


Here are the general steps:
1.  Get the model number of the hard drive.
  A. Take the "new" hard drive, install it into the PC
computer along with the hard drive that the computer
boots from. Get into the PC BIOS setup screen and see
what model number is listed for the hard drive.  On
some hard drives, the number printed on the label is
different that the model number that is reported to
the computer.
  B. Write down the model number.

2.  Get the hard drive parameters.
  A. Exit BIOS setup on the PC and let the computer
boot normally.  Run hdlook.exe on the floppy disk.
Hdlook.exe will display information for *two* hard
drives.   One of the list of parameters should be for
the hard drive that the PC booted from and one list
should be for the *new* hard drive that will be going
into the Grid.  Locate the parameters for the *new*
hard drive that will will going into the Grid.  Write
down lines 3 through 8 (from Cylinders to Sectors).
  B. Shut down the PC, remove the new hard drive,
power up the PC, and allow it to boot normally.

3.  Remove the BIOS EPROMS from the Grid.
  A.  If you've never opened your Grid, now is the
time.  There are two hidden screws at the rear of the
Grid.  They are under the plastic/rubber feet by the
power switch and the parallel port.
Once the screws are removed, pull up and remove the
top cover.  Next, remove the display from its guides. 
Then, remove the hard plastic top cover that surrounds
the keyboard.  Some force is needed to pull it from
the latches near the keyboard.  Use care to not break
the plastic.
  B.  Next, remove the keyboard.  You will have to
remove the screws that hold the latches that keep the
display in the closed position.
  C.  The 2 BIOS EPROMs are located under the
keyboard.  Depending on the revision of your
motherboard, the EPROMs may be sockets or they may be
soldered to the motherboard.
Using a small screwdriver, gently pry the chips from
the motherboard.  If they start to move out, try to
keep even pressure on the chips to keep from bending
the pins.
If the chips does not come out of the board, then it
is soldered in place.  The BIOS EPROMs have to be
unsoldered from the board.  The entire motherboard has
to be removed from the chassis.  To remove the
motherboard, every screw has to be removed to remove
the motherboard.

4.  Read and merge the EPROMs.
  A. Place one of the EPROMs in the EPROM programmer. 
Read the contents of the chip and save it to a file. 
Do the same for the other EPROM chip.
  B. Start your hex editor and merge the two files
into a single file.  In WinHex, do this by: File
Manager | Unify | Bytewise (8 Bit).  Select the first
EPROM file, then select the second EPROM file.
WinHex will then prompt you to name the merged file.

5.  Edit the file.
  A.  First, the text table must changed.  Open the
merged file in the hex editor.  
If you have Revision 1 BIOS, go to address $5038. 
There should be three hard drives listed.  Enter the
model number that you wrote down from step 1B.

If you have Revision 2 BIOS, go to address $754C.
There should be six hard drives listed.  Enter the
model number that you wrote down from step 1B.

If you have Revision 3 BIOS, go to address $763C.
There should be six hard drives listed.  Enter the
model number that you wrote down from step 1B.

In all cases, the text table will have 3 to 6 Conner
disk drive types.  Example: CP322CP344CP3104.  Locate
one drive type and change it to match the model number
you wrote down in step 1B.  
*Warning*: It is OK to overwrite part of the next
entry. But, DO NOT MAKE THIS TEXT TABLE ANY LONGER. 
For example, "CFS3204344CP3104" is OK.  However,
"CP322CP344CFS3204" is NOT OK because the table is now
one byte longer.

  B.  Next, the drive table needs to be changed.
On the PC, start Windows Calculator.  If it is not in
Scientific view, change it by selecting View |
Scientific.
The values obtained in step 2A need to be converted to
hexadecimal.  Do this by entering the value into
Windows Calculator, and then select the Hex button. 
For example, a Cylinders value of 665, will be 299 in
hex.  Convert all 5 values from step 2A to hex.

  C.  "Little Endian" Conversion.  The values above
255 (FF) from the previous step need to be converted
to "Little Endian" notation.  For example, 665
(decimal) becomes 299 in hex.  299 becomes 99 02 in
Little Endian.  4AC becomes AC 04.  2AED becomes ED
2A.

  D.  Compute the new drive values.  Depending on the
BIOS revision, there is a table that lists parameters
for anywhere from 23 to 30 different drive types. 
There are 16 bytes for each table entry.  The table is
in the following format:
                Byte Number
1  2  3  4  5  6  7  8  9  10 11 12 13 14 15 16
CYLD  H  R  R  PRECP R  CT R  R  R  LZ LZ ST R

CYLD  = Cylinders
H     = Heads
R     = Reserved
PRECP = Precomp
CT    = Control Byte
LZ    = Landing Zone
ST    = Sectors Per Track

As an example, assume a hard drive has the following
parameters:
665 cylinders, 16 heads, Landing Zone is located at
664, Pre-Comp is 65535, Control Byte is 08, and the
Sectors per track is 63.
After hex conversion:
299 cylinders, 10 heads, Landing Zone is 298, Pre-Comp
is FFFF, Control is 08, and the Sectors is 3F.
After Little Endian conversion:
9902 cylinders, 10 heads, Landing Zone is 9802,
Pre-Comp is FFFF, Control is 08, and Sectors is 3F.
After formatting for the table enry (the Reserved
values stay at 00):
99 02 10 00 00 FF FF 00 08 00 00 00 98 02 3F 00

Write down the converted values for your new drive.

6.  Editing the drive table.  
  A. In all 3 BIOS versions the drive table begins at
adress $6401 and ends at $66F0. 
  B. Go to the second table entry at address $6411. 
Replace the entry with the values from step 5D.
For example:
67 02 04 00 00 2C 01 00 00 00 00 00 67 02 11 00
would become:
99 02 10 00 00 FF FF 00 08 00 00 00 98 02 3F 00
  C. Save this file.

7.  Split the file.
  A.  This file now needs to separated into two files,
one odd and one even.  This is done in WinHex by
selecting File Manager | Disect | Bytewise (8 bit).
WinHex will then prompt you for the file to be split,
and then prompt you for the name of the file name of
the new files.

8.  Compute and Correct the Checksums.
  A.  Load one of the split files and compute its
checksum.  To compute the checksum in WinHex, select
Tools | Calculate Hash | Checksum (16 bit), or
CTRL-F2.  The checksum of the file must equal the
original value before the file was edited.  For
example, if you were editing the Revision 1, Odd file,
the checksum must equal 0B00.
After editing, let's assume the checksum is now 0BC2.
There is a copyright notice at the begininning of the
file that is never seen.  This text can be changed to
restore the checksum to its original value.  For
example, "43 6F 70 79" can be changed to "00 00 00 1A"
in order to restore the checksum value.
  B.  Once the checksum has been corrected, save the
file and repeated the process for the remaining file.

9.  Burn new EPROMs and boot the Grid.
  A.  Load the files into the EPROM programmer and
program new EPROMs. Place these EPROMS in the Grid.
  B.  Slide the new drive in to the adapter board that
is connected to the floppy drive.  The hard drive
should slide into the bottom of that board.
  C.  Put a bootable floopy disk into the drive and
apply power.  If everything was done properly the
computer should boot.  You may have to press the "F"
key to get the Grid to boot from the floppy drive.
  D.  You should be able to run "fdisk" and then
"format" your new hard drive.

Good luck,
-Shawn

Subject: BIOS Reprogramming Errata

All,
I noticed several typos and mistakes in the
reprogramming instructions.  However, overall the
document is correct in it's procedures.

I am planning to re-do the instructions, but this time
in Microsoft Word.  This document will be complete
with pictures, screenshots, and a FAQ.

I wanted to bring up another important subject that
could be a pitfall ("big mistake" for non-native
English speakers).  If I remember correlty, Phil
mentioned that his hard drive did not fit properly
into his Grid.  (I think) Charles responded and were
misaligned by about 1/16th of an inch.
You both are correct, but Phil brought up something
very important.
If you look at the rear connector on the original
Conner drives, and you start at the left side, there
is an Activity Light connector, the IDE inteface
connector, and then the power connector.  At the
"front" of the drive, there is the Options connector
where the Master/Slave, Cable Select and other options
are set.
On almost all newer drives, starting at the left side,
there is the IDE connector, the Options connector, and
then the Power connector.
Newer drives *will not* slide into the hard drive
interface board on the Grid.

I have a 4.3GB Seagate drive I was going to put into
my Grid.  I know that the Grid will not be able to see
all 4.3GB, but I wanted to see what would happen.  I
soon realized that the hard drive does not fit in to
the Grid.
Before anyone starts buying hard drives on Ebay or at
hamfests, you need to look to make sure that the drive
will fit into the hard drive interface board on the
Grid.

Charles is also correct because I have a 340 MB Conner
that does fit into the Grid.  However, the power pins
are now slightly bent because the pins do not line up
with the power connector on the hard drive interface
board.

Subject: Old Hard Drive non-functional

Of course this is the problem we are trying to solve. However, I was
hoping the only problem I have is that the drive was suffering
from "Stiction". But that doesn't seem to be the case. My old hard
drive will start to rev up its motor spindle for about ten to fifteen
seconds and then it slows down and stops for about five seconds, then
it starts to spin again and simply repeats this process over and over.
The drive is never recognized by the computer. Does anybody know if
this can be fixed, and if so, does anybody know how. Please and Thank
You.

Subject: Re:SUCcESS!!...kind of...

To all,

I have an EPROM programmer, an old PB10 by NEEDHAMS ELectronics which
looks to be quite functional on an old Pentium One I have. I have the 
EPROMS (erased) coming in today I believe so I have everything I
need. I will start with my secondary 1530, which has the monochrome
screen and see how it works using the CP30174E hard drives I have
obtained.

One question: Once I have burned the EPROMS, do I need to cover the
window with anything to keep it from getting accidentally erased?

I am also looking at an EPROM UV eraser which I hope to get soon.

On a side note, I was thinking of getting the math co-processor
80387. The speed of the 1530 is 12 Mhz as I recall. Does the math co-
processor have to be exatly that? Or can it be a faster chip like the
16 MHz or 25 MHz? Also I can't remember if the 1530 is a DX or SX
machine (I think it is DX) If so, does it make a difference as to the
co-processor chip being DX or SX (it seems to me like it would.)
Anyway, thanks for the help.

Another side question: Would EEPROMS work?

Phil,
I think the PB10 will work.  Although, I am not
familiar with that model.
You may have a problem where your Pentium computer
talks too quickly over the parallel port.  In this
case, the EPROM programmer will not respond.  To fix
this problem, might want to download a program called
Moslo (short for More Slowly).  It is available here:
http://www.hpaa.com/moslo/
I paid for Moslo basic (15 USD).
I have to slow my 666 MHz Celeron down to about 80
MHz.  Even at this slower speed, my programmer has
problems at startup.
If the PB10 is a serial programmer, you probably will
not have this problem.

Will EEPROMs work?  Probably yes.  The problem will be
erasing them.  If the programmer can erase them, then
EEPROMs sholuld work.

Should you cover the window?  If you plan to carry the
programmed EPROMs outside (outdoors), or if you have a
hydroponics set up (for medicinal purposes ;)) where
there could be a there could be a lot of ultra-violet
(UV) light, then yes, cover up the window.
I have been programming and erasing mine (indoors)with
the window uncovered and have not had any problems.

I don't have any information about the co-processor. 
I have thought about buying a 287 and installing it. 
Maybe one day when I'm rich and have a lot of idle
time... :-)

Thanks, Shawn,

    My old P1 only runs at 75 Mhz, so I don't think that should be
much of an issue, plus the PB10 is installed as a separate internal
PC card into a slot on the motherboard with its own output to the
module that holds the EPROM. I've already fired up the program just
looking around and reading the old chips from my original 1530. They
seem to work and I can download the contents into the buffer,
although when I looked at the code, it seems the amount of code is
small compared to the capacity of the chip. I haven't tried fusing
the contents of the two chips together yet. Still waiting on my chips
to come in.

I was doing some research on the 80387 chips. There was some stuff I
was seeing suggesting they had to be matched to the particular unit's
CPU make and speed, but then I saw another article that said the
80387's which were faster could adapt to a slower speed (up to 33
Mhz), but that this was not possible with 80287's I'm not sure how
accurate this all is, but I'll keep searching for info.

Subject: Will a 1755 work w/o the CMOS battery?

I need a project yesterday, so I pulled my 1755 out of its case to  
mess around with it. I took it out, plugged it in, and instead of the  
battery + power lights coming on like they usually do, they just  
blinked. but it wasn't a *normal* blink, it was more of a flicker,  
like they weren't even getting enough power to light one fully. I  
checked the power supply (my first thought as to who the culprit may  
be) and it puts out a steady 18.18v, though its rated for 16v (might  
this be a problem?)

I popped it open to see if there were any dirty/unseated connectors,  
and I didn't see any. None of the parts were getting abnormally hot  
(well, nothing was getting remotely warm) or anything like that.  
There's no magic smoke or sparks. I then looked at the CMOS battery,  
(thats what I *think* it is anyways, 10" long, like a pencil with a  
plug and wires at the end) the red wire was broken off completely, so  
it was making the battery (or whatever it is) useless.

Is it possible that this thing not being connected could make it not  
respond to power at all? Maybe I can cut into it and resolder the  
wire? Maybe something worse is happening?

Thanks,
John

The CMOS battery is only there to maintain a voltage on the CMOS chip
to maintain the time and date so that you don't have to enter the
time and date each time you turn the unit on. It has nothing to do
with the power supply and shouldn't affect turning it on or off if it
is bad or even if it is missing. As to your power supply, just
because it provides 18.18 volts when you measure it doesn't mean you
will get that voltage when you put it under a load requiring a
subtsantial amount of current. However, it doesn't sound like your
power supply. I don't know what the CMOS battery for a 1755 would be
like. I have 1730's myself, but they are small fat cylindrical units
that are clearly marked as CMOS batteries, and what you describe
sounds more like a fuse. I've never heard of CMOS battery that was
ten inches long. They simply do not need to be that big. I really
feel it is something else. I would suggest getting some
documentation, if you still have it, or find it on the web, and try
to figure out what that part you are describing is. It may require
nothing more than reattaching the wire if you are sure that it
belongs where you think it does. But I would play safe and find out
what each of those parts are first. You may want to take some photos
and upload them onto this forum. Somebody here might recognize it and
be able to better help you than I'm able to do.

Good luck.

Thanks, Shawn, I appreciate the offer,

Actually, I've played with it some more and figured out how to merge
the files with the EMP program that comes with this programmer. I
found the section where the hard drives are listed. My original chips
from my upgraded unit showed the table with the six standard hard
drives listed as you have noted previously. The program also allows
me to program each of the two chips appropriately as well, so I
should be able to program my odd and even chips correctly. I'm just
waiting for my EPROMS to come in the mail so I can try it.

Also, you had listed before that getting to the EPROMS required
taking out the keyboard. That may be true for the 1520, but for the
1530, the BIOS chips are underneath the video card and only require
removing this card to get to them. The keyboard does not have to be
removed for that purpose(provided that you don't have to unsolder the
chips). Both of my 1530's have their BIOS chips in low profile
sockets so it's not a problem for me. Actually, I think that the 
1530's may all have low profile sockets used for their BIOS chips. It
may be just that some of the 1520's still have BIOS chips fully
soldered in.

It's been awhile since I've been inside the box, but as I remember my
1755's CMOS battery was like you describe, short, fat cylinder. Like
an overgrown hearing aid battery. 

You can still get replacement CMOS batteries for the 1755. They aren't
that expensive.

Phil,
I was wrong.  You are absolutely correct.  The
keyboard does not need to be removed to get to the
BIOS chips.
The problem is I wrote the procedure from memory
instead of actually doing it while writing.  
Getting to the Dallas RTC (if equipped) does require
removing the keyboard.

BTW, I am still interested in the 1530 BIOS file.  If
it's not too much trouble, can you post it in the

Well, first could you tell me what the brand and model number of the
battery is? I tried to look up a replacement battery specific for the
1450 SX, and couldn't find any info on it, although I did find
lithium 3V batteries that were coin sized. As long as we match the
voltage and the amperage output, we should be okay.

Secondly, I don't know exactly what to tell you about the connections
since I am not familiar with it. My 1530's use a different CMOS
battery setup with a cylinder battery. There aren't any plates. If
you could take a picture of it and post it, I might be able to tell
you more.

Ok, I've done some reading and testing, and I have concluded the  
following things:

A) The 1755 has one of those Dallas Real Time clock box thingies. It  
has the Model DS1287, which has a 3v battery *internally*
B) The connector for the long strange battery is labeled RESUME,  
might it be for a momentary backup of the main battery?
C) I've plugged the power supply into the board, and tested the  
voltage level on the DC jack's solder points. When plugged in there,  
it drops to 3.55v.

Here's some pictures, if they help any...

Yeah, all the testing I've been doing is sans-battery, especially
since the + wire on the standby battery is broken off. The main
battery + main battery wires are also disconnected/removed.

To John,
     The pictures are pretty clear. I've never seen a battery like
the one there, but I do believe it is a battery. I think you can go
ahead and resolder the red wire back to it and see if it helps.
However, the "resume" is exactly like what Steve Adams said. It
suggests that this is the battery that maintains power on the memory
so that you don't lose the information to reload the computer when
you take it out of standby.
     When you put the computer into standby, you will shut down
virtually all of it, but you have to store the information in the
RAM and the CPU somewhere so that when you turn the computer back
on, it can reload that information and pick up exactly where you
left off. That requires that you store that information into a
separate RAM (usually) and keep it active until you are ready to
restart the computer. This requires very little current to do this
and therefore a battery can keep it up for a very long time. This
battery apparently supplies the power for that. Not having this
battery in there however, only means you cannot put the computer
into standby.
     It still as nothing to do with the main power of the computer.
What you describe in point #1 of your post is bad news, because it
indicates that the power supply cannot supply the proper voltage at
full load. Even at full load, your power supply should test out at
close to 18 volts. Intead you are only getting 3 volts. That
suggests one of two things. Either your power supply is bad (easy
enough to replace), or there's a short in the power handling section
of your computer (Not so eacy to fix.)
     The best way to test this is to find out the power rating of
the power supply [How many maximum watts does it supply? Just
multiply the voltage (18) by the amperage (however many amperes it
says on the power supply itself), and that gives you the wattage].
Then figure the resistance of the unit at maximum power output which
is voltage divided by amperage (example: 18 volts divided by 3
amperes equals a resistance of 6 ohms). Resistance is measured in
ohms. Then find (buy) a power resistor rated at the maximum wattage
or better at that resistance (ohmage). In the above example 18 volts
times 3 amperes equals 54 watts of power. So find a resistor valued
at 6 ohms, rated at 50 watts or higher.
     Use this as a proxy for the computer and connect the power
supply across it. If the voltage is still 3 volts, your power supply
is bad. If the voltage is back up to 18 volts, you have a short
circuit somewhere in the computer (probably a bad capacitor that has
degraded with time over the years).

No prob, John,
     Just FYI, if it is 1.5 amps, then you're looking at 27 watts and
12 ohms as the specson on the power resistor you need ot use. If it
is 2 amperes, then you're looking at 36 watts and 9 ohms on the
resistor. Good luck.

My two cents worth...

Light bulbs typically make pretty good dummy loads for checking power
supplies.   I don't think that power supply should be able to supply
enough to light up an auto headlight even if it's working properly,
but maybe a couple taillights in parallel...(or maybe just one)?

Prime suspects for drawing excess current and shutting things down
are old batteries.   I'm a bit of a cynic about batteries.  Most
NiCd's have a one year warranty and few of them meet spec after that
period.  The commonest failure mode is the one where it dries out and
won't draw any current but there are several ways they can be shorted
or partially shorted.   I'd say make sure that all batteries are
disconnected and the supply can drive at least one taillight.   If
the Grid still draws enough to pull down the supply then you can
start worrying about motherboard problems...although, even then, the
problem will most likely be in the power supply section.

Anyone ever notice that small signal transistors tend to open and
simply stop working while high power devices tend to short across the
supply and damage other stuff?   Yet another corollary of Murphy's
law...

To Shawn,

Well, this is a followup on the programming.....I have not been 
successful. I am trying to use a Conner CP30174E hard drive to
replace the old one in my second 1530 unit. I have followed the
procedure you have detailed adn checked through it carefully. My
PB10 programmer allows me to merge the files, make the changes and
then allows me to program the chips in split fashion directly from
the program itself. I have followed the procedure and replaced the
second entry in the hard drives list with the designation of this
hard drive which is CP30174E. (It does run over the next entry and
erases the CP from the next entry which was the CP3044, leaving only
the 3044 following it).

I went to the hard drive parameter tables and carefully inputted the
parameter data, all duly discovered using hdlook, converted into
hex, then entered in the appropriate places in the second hard drive
parameter table listing (starting at address 6410), making sure to
enter the smaller byte first when the datum concerned was a double
word. I then split the files and calculated the checksum and
adjusted the logo entry letters at the very beginning of the file to
get the checksum to agree with the original file.

I then put the unit together and booted up the unit. Unfortunately,
it didn't work. I was able to get the unit to boot up just fine with
a boot disk, but at boot up I did get the configuration error 02,
which I am assuming is the computer couldn't recognize the hard 
drive, and then after the boot disk got the thing into DOS, I tried
FDISK which couldn't find any hard drives present.

I tried this four or five times, reprogramming the chips after going
over the files again and making sure I got them correct as per the
protocol, and using two different CP30174E units. I know the hard
drives are okay as I tested them out on my PC machine first But
still no go....

Any ideas or input out there?

Thanks for the help.

Phil,
I'm in a rush right now but I wanted to get a response
to you as quickly as possible.
The Grid booted from floppy, right?  The simple fact
that it booted from floppy indciated that your BIOS
editing was done correctly.

What is the status of your Dallas RTC or the Tadiran
CMOS battery?
I have found that if the CMOS battery is dead, you
will get a Invalid Configuration.  *I assume* that
when you get that error, a default configuration is
loaded.  It appears that hard disk support is not a
part of the default configuration.
I can't offer an explination as to why this happensnor
do I know where the BIOS gets this "default"
configuration.  All I know is from my testing, if the
battery (or RTC) is dead, you can't see the hard
drive.
I hope that helps.

To Shawn,
     You are correct in that I was able to get it to boot normally
from the floppy. It just didn't see the hard drive. But then I'm a
little surprised that the CMOS battery would be required to allow
the computer to recognize it. I've had to replace the battery in my
original 1530 once before, and while it was dead, before I replaced
it, the hard drive came up okay. To be honest that doesn't seem
right to me. Now this newer unit doesn't have its battery in it now.
I was planning on putting it in once I got the hard drive going. But
I'll go ahead and try and see if it makes a difference.

But there are some other questions I have as to whether I programmed
the thing right.

Does it matter in which position I put the parameters in the
parameter table? I put in these parameters in the second position in
that table since I listed the hard drive in the second position in 
the Hard Drive table.

How does the computer know when to stop reading for the hard drive
designation? Does it just stop and accept it when the complete name
is read and matched to what is on the hard drive, or does the "C" of
the next hard drive name act as a stop character?

As to the Dallas RTC chip, as far as I know it's okay, but how do I
check that?

Thanks for the help, and I ubderstand you're in a rush, so whenever

I agree, it does not seem right to me either.  But my
1502's won't see a hard drive unless the CMOS battery
is there or the Dallas RTC is good.

I don't know this either.  I have questions about this
as well.  The space is 35 bytes.  35 isn't a nice
computer number.  By that I mean that 35 is not a
multiple of 2^n.  Also, each hard drive parameter has
a different field length.  Some are 5 characters
(CP344) and others are 6 characters (CP3022).
I notice in the 1520 BIOS file and the 1530 BIOS file,
the last entry is CP3104R.  Perhaps the 'R' is a
character that signifies the end of the hard drive
list.

With a voltmeter, check between pins 16(-) and 20(+). 
Here is a site that lists how to hack the 1287.

Subject: Re: Larger Hard Drives in a 1520 (Success...finally)

Shawn,

   The CMOS battery didn't change anything. I was able to add it in
and I still got the failure code 02. I put in the new date and time,
and when I rebooted, the new date and time held up and stayed in the
system, so I know the battery is inputing where it should in regards
to that. So maybe the battery is needed for the 1520 in terms of
making the HDD work, although to be honest I still have my doubts
about that. However, for the 1530, it looks like the CMOS battery
doesn't have anything to do with getting the hard drive recognized.

   However, I did notice something else. I went ahead and looked at
the BIOS chips from my 1530 which has the plasma screen. The code on
that BIOS is significantly different, but the hard drive and hard
drive parameter tables are in the same places as the other unit which
only has a monochrome screen. When I upgraded my original unit, I
also upgraded to the CP 30104 100 MB hard drive. But now I see that
drive is described in the hard drive table as CP3104, the last drive
in the table. It has to be that one, as there is no other drive there
that fits the CP30104 which was working originally in my upgraded
unit. So that tells me that maybe they only had enough room in the
hard drive table to use four of the numbers for that drive. It makes
sense as they originally planned to be able to use a certain number
of hard drives for the unit when they were in production back then,
and the CP30104 100 MB unit was one of the ones you could opt for,
though it was not standard out of the box. You could upgrade to it,
and thus the information for it was in the hard drive table, but I
think as CP3104, because they didn't have enough room for five
nuumbers.

   Secondly, looking at the hard dirve parameter tables, as you have
noted, there are a lot of differently described parameters, a lot
more than six. When I looked carefully, I think I noticed a pattern.
In my parameter table, the list goes on for about 45 different
descriptions of hard drive parameters. but the first ones have
smaller numbers in them for their cylinders and heads, and they
steadily increase. You mentioned in a previous post that the first
hard drive listed in the hard drive table is the default 10 MB HDD.
Then the next one would the 20 MB HDD, the next a 40 MB HDD, and so
on.

   When I was looking at the CP30174E's I have (I've procured four),
I noticed they weren't all the same in terms of their parameters. One
of them had 903 cylinders, 8 heads, 46 sectors per track. Another one
of them had 1303 cylinders, 15 heads, and 17 sectors per track. A
third one had 651 cylinders, 30 heads, and 17 sectors per track. Yet
these were all the same designated drives, all CP30174E's.

   Maybe these early hard drives, for whatever reason, possibly
depending on different manufacturing processes, can have the same
name in terms of the drive itself, yet individual units might have
differing parameters. If so, that might explain why there are so many
different configurations listed. It may be that the first five or six
listed parameter groupings, which have lower numbers, correspond to
the possible parameter combinations for the 10 MB HDD. Maybe then the
next five or six or seven correspond to the next designated HDD from
the hard drive table and so on. I haven't done it, but I'll bet if
you take each cylinder count, head count, and sector count from each
table listing and multiply them out to get the capacity of the listed
drives, I'll bet you'll find the first few sets compute out to 10 MB,
the next several to 20 MB, and so on.

   I know I'm speculating a bit, but I think I've got some pretty
good data to go by. I'm going to try again with the CP30174, but what
I'm going to try is to change the last entry of CP3104 to CP3174, and
see how that works. And for the parameter table, (if I'm right), I'll
compute where the 100 MB section begins, and try to add in the
parameters of the 170 MB HDD there. If that doesn't work, I may go
back to trying the second entry again.

    I have also obtained a CFS420A. I believe that's the hard drive
you got for your 1520. (?) If so, would you mind sending me a copy of
your BIOS so I can see how you put it in your tables (or maybe you
already uploaded it to the file section. I'll have to check.)

    I'll get back to you on the Dallas Chip. It doesn't seem to be
the problem though.

    Anyway, anything you might know that might enlighted me on all
this (or disprove me, which is fine too) would be helpful.

Thanks

Phil

Subject: Replacing the DS1287 with a DS12887

     The DS1287 can be replaced in some computers with the DS12887 or
DS12887A. The DS12887/DS12887A is still available for purchase. I
have uploaded the file concerning this directly from the manufacturer
(Maxim Electronics). The only question that came up is that the
DS12887 cannot replace the DS1287 in some computers because the
compuer will try to access the wrong time clock registers within the
DS12887 circuitry. In that case, the computer will not boot up.
However, in an earlier post, someone has already tried this fix and
it seemed to work. It looks like that the dead DS1287 may be the
cause of the invalid configuration code 02 that you will get on
bootup. I've reposted that post below:

BigWalk uploaded a file on the DS12887 circuitry, but I uploaded a
file dealing with replacing the DS1287 in a PC which I hope is
helpful.

I started looking into this because I was in a Fry's electronics
store looking for a battery holder (for the 1/2 AA cell lithium
battery) when I came across two DS 12887 chips individually packaged
for sale at the store. I also found battery holders for the 1/2 AA
lithium batteries and I will plan on using those for easier
replacement of the battery in the future.

Now this is the strange thing. In the 1530 I just obtained, it does
have a DS1287 RTC in it. However the original 1530 I have owned since
I bought it in 1986 does not. Looks like it's a completely different
revision. Go figure... :)

Anyway, I guess I'll have to replace the RTC in the first 1530, as it
appears that the invalid configuration 02 may be due to that.

I now have 4 1520's.  3 (motherboard revisions E and
AE) have Tadiran batteries for the CMOS.  Board
revision AR has the Dallas RTC.
Additionally, member "Zentaro" (Andrea), has a
revision "1/90" that has the Dallas RTC.
A couple of months ago, Andrea posted a link to
pictures of his 1520.  He made a modification that
extends the battery leads of the 1287 to a more
accessible area (by the RAM) where a battery can be
attached.

CMOS failure...

Unit says the record is corrupt, strike F1, when you do so it resets the CMOS to default, never resets or tests the drive and attempts to boot from a floppy.

Do not turn the GRiD off, use a keyboard reset <Ctrl><Alt><Delete>
The system has set the CMOS to default.  If you cycle the power you loose the default settings and start from scratch.  Since the reset command has naver been sent to the interface it sounds like the drive didn't start properlly.

After the keyboard reset (three finger salute) the system will respond with a real time clock error (strike F1) than boot from the hard drive.

Thanks, Charles,

    I appreciate the advice. Fortunately, the problem was simply that
the Dallas 1287 RTC was dead. I managed to procure its replacement,
the Dallas 12887A chip (which you can still order if you don't
already know, about $20) and replaced it on the motherboard. The old
CP3044 hard drive was also dead (motor simply did not run at all),
and I replaced it with a Conner CP30174E. As per Shawn's protocol,
which he has put up in the files section, I used a Needham's PB10
programmer on an old 75 Mhz P1 machine running DOS to burn the new
EPROMS for the BIOS, writing the name and the parameters of the new
hard drive into the appropriate tables (second entry listing was
replaced in each table BTW), also correcting the checksum
accordingly, then made sure the C/D and ATA/IDE jumpers were placed 
on the front of the drive (to enable the whole drive being able to be
formatted instead of hitting a 32 MB limit), and put the whole thing
together. Both the new Dallas chip and the changes to the BIOS are
required to enable the computer to recognize the hard drive
and it worked beautifully. The computer is now running with MSDOS
6.22 loaded on it with a 170 MB HDD.

Subject: Grid 1500 Harware Service Course; Student Guide

Hey guys,
    In a recent missive to Shawn, I told him about something that I had
completely forgotten about. I had been in touch with GRiD back in the
early 1990's about my 1530, I think about the time I had it upgraded,
and I wanted to know more about repairing it and knowing about its
inner workings. I don't remember exactly how but somebody at Grid (or
Tandy, I can't remember which), sent me this strip bound tome with the
above mentioned title. This thing is huge, about 500 pages front and
back. I had completely forgotten I had it until just recently. There is
a lot of very good data in this book and it is aimed specifically at
giving out dinformation on the repair of the 1520 and 1530. There are
things like pin assignments, beep codes, adn all other sorts of
technical data that I think would be very helpful to all of us here.
Give me some time as I am going to scan and turn it into a .pdf file.
It may take a couple of weeks or so.

Phil,
Thanks for your help and time with that effort. 
Scanning close to 1,000 pages is one big pain in the

I know I'm looking forward to seeing the book when
you're done.
Thanks,

My first post, as the proud owner of a 1520 with a dead hard drive  
(at least):

Phil, you may be able to get the book scanned by a "data conversion"  
firm for low hundreds of US$, if your time is worth more than that.  
They will have a fast, purpose-built scanner with a document feeder.  
Usually, the scanning intent is for OCR, so the scan would be less  
than 200 DPI I imagine.  Surely you can negotiate the output.

This is info I collected after doing a large OCR job with a flatbed  
scanner! It would have been much cheaper for my client to start with  
a fast machine (neither of us knew at the time).

Thanks, Mike.

Actually I have looked into that. Fedex Kinko's for example will do
it for 99 cents a page, and I could work a deal for a cheaper price.
However, I don't really wish to spend that kind of money. It's
actually a lot cheaper for me to buy a multifeed scanner myself. I
already bought a used one for about a hundred bucks, and am waiting
on it to come in.

One reason I'm doing it this way is so that I can scan the book into
Adobe Acrobat directly (I have the full version 7), and get it OCR'd
at the same time so that you can use Acrobat Reader's features to
look up anything on it you want, which an outsourcing deal probably
won't give me. The multiscan feeder goes at about ten pages a minute,
so that's why it'll take a little while.

I don't mind spending the time, and I can't justify spending quite
that much money on duplicating the book electronically.

I'll let you all know when I'm done. :)

Dear Ken,

     Unless you had a couple of million dollars to spend, money is no
big object, within reason of course. (grin). :)

     I will be glad to share the information as I will be posting all
of the manuals in the file section. However, I can only hope the file
section can take them as two or three of the full manuals will be
very large files. In that case, other arrangements can be made.

     I must confess that this is taking a heck of a lot more work
than I had anticipated, but I'm glad to do it. If you or any of the
other members of the forum could help, I would like to obtain some
1MB memory sticks for my working 1530 as well as the parts to upgrade
to a backlit plasma LCD. In regards to the memory, it presently only
has eight 256Kb sticks and I would like to upgrade it to the full 8
Mb it can take. Would you happen to know where I could get eight of
those sticks or the LCD plasma display?

Phil

I assume you have better OCR software than I do.   Whenever I scan a
lot of text I end up spending a ridiculous amount of time doing clean-
up. Scanning to a jpeg is easier on my time but results in enormous
files.

Since Yahoo recently upgraded groups file storage to 100Mb there
should be plenty of space for the pdf.

One of my Grids came with a set of user manuals and the thought of
scanning them did cross my mind but, as I said, there seemed to be a
lot of clean-up involved (and I doubt that it would be worth hundreds
of dollars to me to pay someone to do it).   I wouldn't be opposed to
the idea of sending them to someone else who wanted to copy them, of
course...

It depends on which program you use. I've scanned whole books into
Wordperfect and come up with an editable text that I later scanned
back into PDF format which was very time consuming as I ended up with
a very editable document that I could do all sorts of things with,
but that took an incredible large amount of time.

This time I'm using Adobe Acrobat Full version 7.09 and directly
scanning the documents into that with maximum accuracy on the scan at
400 dpi. You can't edit it per se, but you should be able to do
search functions.

It's working out pretty well actually.

 WOW what a find Phil !! Not only for you but for all
the GRID 15xx enthusiasts, and that you have the
graciousness to want to share it with us. With Shawn
having seemingly unlocked the HDD secrets of the BIOS
our cup overflows.
 I was able to upgrade a 1520 with low-profile SIPPs a
few years ago that I got on EBay. They're a PIA to
install and I destroyed the pins on 4 of the 8 I
acquired. Up until the last gasp of my Conner HD I had
Win 3.1 installed. I've occasionally seen offers for
them on the vintage collector forums. I had also found
a company that still sold them but they would only
sell in large quantity. I'm afraid I've lost their
address however.

Thank you, Lawrence

       I'm most happy to share. But I also appreciate the
reciprocity. I'll look for the low profile SIPP's on the vintage
sites, but if you could possibly find the name of that company that
makes those memory sticks, I would like to look into what I could
with that information. I would appreciate it.

       Right now, I'm halfway through scanning these manuals. I have
to go out of town this weekend, so I will be back and should finish
the scanning next weekend. The technical manual by itself looks like
is going to be about 100Mb even as a PDF file, so I'll see if I can
get it on the site then.

'til then guys. Hate to make you wait, but real life goes on. :)

 OK, here is an old communication I dug up. Can't find

response.
Possibly I acquired the SIPPs on EBAY about that time.
 Don't know if this guy is still even working there,
but there is an 800 # and they still have a web

 There are a multitude of Vintage computer sites out
there and most have For sale or trade and WTB

 I believe I saw the SIPP offering several years ago

Subject: Grid 1520 Booting from Compact Flash

Just thought I'd let everyone know that I'm working on
getting my 1520 to boot from Compact Flash.
My first attempt ended in failure.

I modified my BIOS with the information from hdlook.
With the compact flash out of its carrier, on boot up,
I get a confusing memory error.  I do not have my
notes with me so I cannot give the exact words. 
However, it says something like "Memory Error at
address (XXXXX, I can't remember).  expected FFFF,
received FFFF."

Accroding to the message, the computer received what
it expected, so there shouldn't be an error.

The Grid continues to boot but only allows me 640K of
memory - out of 2 meg installed.

If I insert the compact flash, the computer does a
series of beeps, and then nothing.  I think the beep
sequence is 1 beep, followed by 3 beeps, then 1 beep.

The CF is a 512 MB, type 1.
When I get some free time, I will try my 8 MB CF that
came with my digital camera.

Shawn,
    Once I post the manuals this weekend, the beep codes are included
in there which can tell you what that means. I'm out of town right
now so I can't look it up, but it will be available to you soon.

Subject: ATTENTION! ATTENTION! The Manuals have arrived!..........For the most part!

Okay! To Shawn, Lawrence, Charles, and the rest of the gang. The PDF
files of the manuals are now posted, except that the Technical
Reference manual could not be put up completely because I ran out of
space in the files section.

To the Moderators (Shawn, Charles), I apologize for usurping all the
rest of the space alloted for the files section, but I didn't know
Yahoo had that limit there.

You will see that the following manuals have been put up as whole
documents:

GRIDCASE 1500 Field Diagnostics
GRIDCASE 1500 Disassembly_Reassembly Instructions
GRIDCASE 1500 No Boot Procedure

The following document is 7 MB in size, 60 pages, and is posted in
two parts as the individual file size limit that Yahoo restrict us to
posting is 5 Mb:

GRIDCASE 1500 Series Hardware Service Course Student Guide

The following document is 12 MB in size, 121 pages, and is posted in
three parts:

GRIDCASE 1500 Series Hardware Service Course

The following document is 32 MB in size, 181 pages, and comes in
seven parts:

GRIDCASE 1535 EXP Owner's Manual

However, this is where I ran out of space in the files section. This
last document is by far the largest. It is 132 MB, 358 pages, and
comes in 28 sections due to the individual file size limit of 5 MB:

GRIDCASE 1500 Series Technical Reference Manual

I could only post the first 10 sections of it. There is no more space
to post.

I would like to recommend to the moderators that they create a
special section of the forum for these particular documents since
they are the actual repair guides and technical manuals for the
computers. At the least, could we get more space alloted to the forum
for the files section so that I can post the rest of the technical 
manual sections.

I would also recommend that once you downlaod the sections of the
manuals you wish to have that you use Adobe Acrobat (if you have the
full version) or some other PDF document handling program to combine 
the sections into the single documents as they were meant to be.
Otherwise, I suppose I could just burn some CD's and send them out.

Anyway, to the forum, HAPPY EASTER (or Passover, or whatever)! and
enjoy the manna from heaven! :D:D:D

Fantastic, thank you!

Do you have a ZIP program? If you compress these PDFs, you might take up 
less space.

Not that you need to spend any more time on this; in fact, once I have 
the PDFs, I'll compress them myself. Then we could swap PDFs for ZIP 
files maybe.

Shawn,
      How do I get the rest of the files to you for your FTP server?
Michael Alwin suggested compresing the files and I tried that, but it
only compresses the files an average of about 10%, so that's not
going to be very effective.

      Of course, I would just as soon send you the whole file so that
it doesn't have to be reassembled, but whatever works is fine.

      How can we do this? :)

Compression sounded like a good idea but Winzip only compressed a
3.6Mb file to 2.96Mb...could probably get better compression using
another zip utility but not good enough to cram in another 132MB.
Hosting on another site would probably work best but a stopgap
measure might be to open another yahoo group just for files...it
would give another 100MB.   (note that this is a new limit...just a
few months ago their limit was 10Mb)

There's one other thing to try with PDFs: from the file menu you can 
choose "Reduce File Size" and resave; or from the "Advanced" menu choose 
"PDF Optimizer." Both will decrease the DPI of scanned images, and strip 
out other unnecessary code.

It's best to save as a different file name, so you can check that images 
were not being degraded so much as to be unreadable. If "Reduce File 
Size" is too drastic, one can fiddle with the Optimizer settings.

You might have tried all this before. (I live in Acrobat, begin in the 
publishing industry.)

Hope that helps.

Thanks for the suggestions, guys.

   I don't want to decrease the PDI of the scan because some of the
print is hard enough to read, which is why I didn't want to do that.

   However, I've already solved the problem in that I have uploaded
all of the files to Shawn's server. So he has them all now. I'm sure
he will let you know the information needed to contact his server and
download the files. What I'm going to do is delete the partially
listed tech reference files so that there is room left in the files
section for other people to be able to upload other files. I'll leave
the rest of the files up for now, though eventually I may need to
take them down and after that, all accessing for those files will be
done through Shawn's server, if that is okay with him.

Hi again, guys,

    Just to let everybody know for sure. All of the manuals are still
in the file section EXCEPT for the Technical Reference Manual. That
one is the biggie. (It has everything in it.) Just to let you know, 
Mike, I did try zipping the files but as was mentioned, it only took
the file size down by a measily 10%, so that didn't work either.

    Now when you get around to accessing Shawn's server, you won't
have to download the separate parts. You can download the entire file
all at one time, and you won't have to worry about joining them all
back together again.

Subject: Time of Day Password again.

Sorry, guys,
     I know this has been discussed elsewhere, but I can't find the
thread. I just obtained a 1520 for myself. The RTC was dead. It had 
only one Mb RAM and just the 20 MB hard drive. Long story short, I
replaced the RTC with a 12887A, upped the RAM to 4 MB (I was able to
score some sticks), and replaced the hard drive with a 170 MB HDD,
burning the new BIOS chips accordingly. Now when I fire it up, I
getting to the point where it says the time of day clock is stopped and
then to press F1, which of course gets to a line which wants me to give
the unit a password before it will finish booting.

I know this has been discussed before, but could someone tell me how to
get past this or direct me to the right thread?

Thanks.

Phil

Subject: GRiD 1500 Technical Manuals

All,
Thanks to Jerridan (Phil), he has taken the time to
scan and uploaded the manuals to my server.
The total size of all of the documents is about 345
MB.

My server does not run the standard ftp service.  The
server runs vsftp (Very Secure File Transfer Protocol
- the word "secure" is a relative term).  Anyway, if
you are running Windows, you need to download and
install a sftp client.  Here are 3:
winscp3: http://winscp.net/eng/index.php
PuTTY:
http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
and Tunnelier: http://www.bitvise.com/tunnelier

WinSCP3 is probably the easiest to use and get going.

Once they are installed, you want to connect to my
server with the following parameters:
Name: griduser
Password: griduser
Server: shawnerz@...
Port: 22

Once you connect, you should be able copy the files.
Let me know if you have any problems.

-Shawn

Subject: Re: GRiD 1500 Technical Manuals

To all,

     My appreciation to all for your kind words. When you access
Shawn's server, you will find seven complete files as I have
indicated before in my previous emails. If for some reason you need
to download the files in smaller segments, there is a folder that is
labeled "files in 5 MB parts" which is where I have the four larger
manuals copied in small 5 MB file sections. However I doubt you will
need to do that since that was done purely to get the files onto the
Yahoo website, and that is no longer needed. So just download the
complete files from the "grid" folder

     Because of the duplication of the files in parts and as a whole,
the actual space taken up by all seven complete files is about 183 MB
in the form of pdf files. With the addition of those 5MB partitions,
it came to about 345 MB.

     I recommend the WINSCP3 program as it is free and worked
perfectly for me.

     I will leave the first six files up on the website for now for
those of you who want to download it that way, but it is far easier
to download it off of Shawn's server since that way you don't have to
download partitioned files and have to rejoin them on your own
computer. Eventually, I will take those files off of the file section
from the web site so that space is freed up for people to be able to
post other important files.

     Thanks for your support.

Phil

I have found it extremely difficult to find the sipps, however for lack
of them, you can still find the 30 pin SIMMs more easily. Shawn has
already posted a thread where you can convert the SIMMs to SIPPs simply
by soldering on the pins. I know that's a bit of work, but that may be
the only option you may have, since the SIPPs are now really become as

I was hoping no one would remember that thread. :(

I had three problems that prevented my SIMMs from

My SIMMs are too tall.  The top of the SIMM comes in
contact with the top cover.  
The SIMM was too long.  The SIMM extended into the

Lastly the pins from the DIP socket that I used were
not rigid enough.  I would try to push the pins into

Maybe some one has a better idea.

Thanks again Phil, AND Shawn !

 One possible solution with the files section size
limitation is creating a second group called "Grid
1500 files".

 This is used by another group "atari midi" which I am
a member of. That takes the heat off the primary site,
which could only have essential files or programs as
determined by the moderator.

 The files upload site would contain lesser files.
Even longer files or programs can be hosted by an
external server site, in Atari Midi's case, Tim
Carmody's Atari midi site or in our case, if Shawn is
willing, his server. Anyone willing to take up the
task could also establish a mirror.

 A surplus of space could even make me aspire (even
from shame)to emulate Phil's and Shawns efforts and
upload the SCSI adaptor manual or other stuff. mea
culpa, mea culpa. I think many kudos also has to go to
Mike Brietman for having helped to enliven this forum.

Subject: Re: Time of Day Password again.

Hi again, guys,

     I've done some preliminary investigation on this problem with
the. It appears that replacing the RTC chip on the 1520 is
problematic if the RTC is not first initialized. When that happens,
the computer sees it as having "stopped" (i.e. the message "Time of
day has stopped"), the BIOS then prompts you to press F1 and then
enter the BIOS password. The problem is there is no documentation as
to what the password is.

     This is an old phoenix BIOS, of course, and they have several
backdoor passwords
including "phoenix", "PHOENIX", "CMOS", "cmos", "BIOS", and "BIOS".
I've tried those as well
as "GRiD", "grid", "GRID", "gridcase", "GRDICASE", "GRiDCASE",
and "Gridcase". None of them worked however, and I'm wondering if the
BIOS even provides a password matching routine to allow a correct
answer. The problem then results in the machine simply rebooting when
an incorrect response is given, and then you simply run into the same
problem again. For some reason, the BIOS on the 1530 didn't give me
this problem when I replaced the Dallas RTC on it. It booted right
back up again very nicely, probably because they had seen that
problem and corrected it by then, but never bothered to go back and
fix it for the 1520.

     Some others on the web have had the same problem and the
consensus has always been there is no choice but to take out the
Dallas chip and replace it. But then you still have the same problem.
On some 1520's that didn't have the Dallas chip, but with the other
timer chip and where the battery is separate, one person was able to
leave the battery out for about a week, allowing the time keeping
registers of the RTC chip to finally go dead after the capacitors
lost their residual charge. Then he was able to put the battery back
in and the time chip was able to initialize and the machine booted 
properly. But because you can't disconnect the battery from the
Dallas RTC (unless you do the German modification that Shawn found),
that's not a option. I'm still considering doing the German
modification thing (externalizing the battery), but I was also
wondering about the following.

     Has anybody considered reverse engineering the BIOS a little? It
doesn't sound too hard to be able to add a small routine that would
initialize the RTC upon boot if it was found to be stopped,
(especially since they seemed to have fixed that in the 1530 BIOS).
Now it's been a long time since I messed with Assembly Language, and
I remember precious little of it, so I have a lot of studying to do
(again), but I was able to get a Disassembler and break the BIN file
back down to an .ASM file. Now I have to study it and parse out where
this whole routine concerning the clock gets in there. If I can
pinpoint it, then there is one of two things I can do. I can either
try to write a routine that will initialize the clock when it has
stopped, or I can find out if there is indeed a password to which the
BIOS will even compare an answer, in order to accept it and then boot
up. I still have my old programs and books on MASM 5.1, so since this
is a very small modification, I'm hoping it won't be too much trouble.

     Anyway, does anyone have any thoughts or comments on achieving
any of this, or helping out? Thanks for the input.

Phil

Now that I have replaced the dead battery (older revision without the
dallas chip, wewt) I am back and running. I'm now looking into a
coprocessor. Anything out of the ordinary to be noted (besides the
speed of the coprocessor) or should dropping an 80287 in and
reconfiguring the system be all that's needed?

I don't know if you need to do any system
reconfiguration.  You're going in to new territory for
me.
I would think (big assumption) that all you'd have to
do is drop in the -287 and continue.
Let us all know how it works,

One thing I have noticed,

Using various sized of flash on some new products (top secret ya-know)
Many times the flash will only operate in native mode.  Native '0' mode for a hard drive is that state where the drive reports exactly what the physical geometry of the mechanical - - - um - - - 'drive' 

Example.  A CP3044 actually only has two physical heads, the rest is virtually converted on the controller board and shipped to us in pre-ATA  um.....  ATA fashon. 

Perhaps the GRID is prefering mode  1 or mode 2  to access the more genaric vertuial geometry of the conner hardware.

Subject: Manuals Availible via ftp

All,
I think I have the ftp portion of my server up and
running.  If you havn't downloaded the manuals because
you didn't want to install the ssh software, you can
now download the manuals in Internet Explorer
(assuming I have everything set properly).
In the address bar, enter ftp://shawnerz.homelinux.org
At the user and password prompt, enter griduser, and
griduser.
If everything is set correctly, you could see a list
of the manuals that Filipe (sp?) uploaded.
If your never connects and you get an endless
hourglass, go to Tools | Internet Options | Advanced.
Scroll down to the Browsing section and uncheck (or
check) "Use Passive FTP (for firewall or DSL modem
capaiblity)"
With it checked, IE is supposed to use passive mode
and lock itself to ports 20 and 21.  However, with my
checks using Win2000, it seems to work opposite of way
I think it's supposed to work.
Please let me know if it works for you.
Thanks,
-Shawn

the login and password need to be embedded in the URL and damned if I
can remember the format for it.

just using the posted URL makes it an anonymous login which the server
does not support.

what you might want to try is to make a gmail account and see if you can
post all the files to the account then just give everyone the info on it
and hope no one deletes the files.

Len and Phil:
No, the login does not need to be embedded in the url.
 I don't seem to have a problem from my PC at work. 
I'm running Win XP and IE7.
My server does not support anonymous login.
My Win2000 computer running IE6 at home doesn't have
any problems either.  Since that computer is on the
same network, I can't say it was a valid test.

I do know somebody was able to download last night
because I saw activity at about 12:30 AM (Eastern).

Perhaps the service is being blocked at your end.  Is
your firewall blocking the connection?  Are ports 20
and 21 open on your router?  Are you able to ftp from
other sites?

Thanks,

That was me--I got everything. I experienced a fairly slow connection, 
BTW, so left it going overnight.  Took a few hours to download everything.

On a Win2K computer, I start Internet Explorer 6.0 and drag the FPT link 
from the e-mail to the browser. The browser connects to the site, and

 I'm certainly nowhere up to your level of expertise,
but have you tried the old trick for eliminating a
lost
password ? You grounded the reset pin and that wiped
out the password. Can't remember what the pins you
shorted were but it should be in the RTC doc in the

BIOS which contained the password. Simplistic but who

Thanks Lawrence,

Well, I wouldn't say I'm an expert in ASM. I've dabbled in it and know
some basics. However, I have tried shorting out the pins (which BTW are
pins 12 and 21, 12 being the ground pin, and this did not work. I found
out from the Dallas 12887A spec sheet that this will wipe the data off
the Dallas chip of all the non-time keeping registers, but not the time
keeping registers themselves, which are the ones that have to be
initialized. So that won't work either.

My theory is this. If the computer is offering a way to get into the
BIOS through the password, then if it can be done, all I have to do is
reset the clock and it will be initialized. However, there is no
program to get into the BIOS on a 1520 (or 1530 for that matter),
therefore there is no answer to the password question. The thing to do
is to go directly to routine that will set the time and date. Once I
map out the ASM routines and figure out where it goes into this, I can
just alter one jump instruction and I can bypass the whole thing and go 
directly to boot.

But this is going to take some time to figure out. If I can, then I can
make the routine to other users to burn into their EPROMS.

I'll let you know what I come up with (hopefully).

Lawrence,
You must have started your download after I made some
changes to the server (~10PM Eastern).
I don't know what the proper name for the attack, but
the server was getting a bogus login request every
second from the same two IP addresses.  The IP
addresses are probably spoofed.
I think the attack is designed to cause some sort of
buffer overflow.
I installed a Linux application called "fail2bin".  If
you try to login with a wrong password for more than 3
times from the same IP address, the server locks out
traffic from that IP address for 10 minutes.

So, if anyone from the group tries to login and is a
bad typist, you've got three times to get the username
and password right.

As far as other people having problems, one idea comes
to mind.  By defualt, Windows first tries an anonymous
login.  My server does not allow anonymous login. 
Internet Explorer should prompt you for a name and
password.  In Windows (File) Explorer, select File,
Login As... and put in griduser for the name and
password.

I hope that helps.

Subject: Re: Time of Day Password again.

To all,
    In an update, I think the best thing for me to do is to look for
the choke point in the program where the program in the 1520 BIOS
calls the TTY write routine to print out on the screen "Incorrect
Password - Press any key". It is at that point that any key that's
pressed reboots the machine. All I have to do is redirect that
instruction to where it is supposed to go afterwards to continune the
booting. Once that is done, I can do Time and Date, and the time ship
will be initialized. But that will be a little problematic also. The
alternative is to confirm what the password is (or actually provide
it with one) so that question can be successfully answered. I've
begun separating out the subroutines in the ASM file to try and
figure them out. So far I've only found is the TTY WRITE (write
characters to video). There are not that many routines actually. The
actual BIOS opcode amount is really very very small. Mostly it is to
initialize the hardware interrupt vectors then redirect to the floppy
or HDD to load MSDOS. The technical manual has data to refer to the
interrupts used in the time control chip(s), and this will help.

    But this is VERY slow going trying to interpret all this. It's
hellaciously hard. but I'm hoping that I only have to change one or
two lines of code. If so, I may be able to change it directly in the
BIN file without trying to recompile the BIOS altogether.

From: "jeriddian"
Subject: Re: serial port

If the computer is the problem, it probably comes from inside the
machine. The modem is hooked into COM1, while the serial port goes
through COM2 in these old units. I don't think it comes from a lack of
power coming out of one of the pins you're measuring in the 9-pin plug.
There are dual 82C50 UART chips in the machine, one for each COM
connection, and some associated circuitry. Thew worst case scenario
would be that it may be one of these chips has gone bad, but I can't be
sure. I have the tech ref manual and have gone through it, but I can't
find a specific reference to the error message you're citing for us.

Also, could the problem be in the radio instead of the computer? It
sounds like the error message is coming from the program itself, and is
not internal to the computer, therefore I wonder if the radio is the
problem.

I know you only have one set of everything, but the easiest answer
could be just a bad connection, so if it is possible to obtain or build
another set of connectors to test this out, this would be the first
thing I would do. This would require looking at the aftermarket
connecting cable and finding the right parts to build a replacement (or
testing the connections individually if the cable is nothing more than
wires connecting through, provided you know the proper connections.

The second thing I would do is get the diagnostic programs for the
computer and run it through to test and see if the serial port is
working.

The third thing I would try is if you have some sort of old hardware
that connects through the serial port (like a simple mouse program and
and old style mouse, or something like this. You could try connecting
an old style modem and installing the software to see if it would work
on a dial up connection as another example.)and if you could prove this
would work through the serial port, that would seem to rule out the
computer as the source of the problem.

Anyway, good luck. I hope this helps.

Hello there, Jim.
I saw Jeriddian's response but I wanted to add a
couple of things.
If you haven't already, you might want to download
conf1520.exe from the Files section.  The syntax is
fairly straightforward.
Try 'conf1520 serial=on' and see if that makes a
difference.  You can also type 'conf1520 /?' and it
will list the commands that are available.
My guess is it won't make a difference.

>From your post:

I assume you're using an aftermarket RIB and cable.
Did it *ever* work?  Or, did it work at one time and
then just stop working?

Again, I'm assuming that you're running RSS.  Again,
did it ever work?  Is RSS configured to use the
correct serial port?
As I'm sure you know, RSS is a pain in butt to use.

I've got a XTS3000 with a real RIB but aftermarket

Grid.
Good luck on the MCX.

From: "jeriddian"
Subject: Final Success - My 1530 is BACK! Some important things to know, too.

Well, it took some doing.

Basically, I had to use another 1530 that I bought over the net. It
was a basic model with minimal features, except it has the gas plasma
screen instead of the monochrome. It had only 1 MB memory, and the
Dallas chip was dead. Also, the 40 MB HDD in this unit was about to
go out. It would power down suddenly and freeze the machine every now
and then. I wanted to transform this one with the features I had
originally had in my old 1530 as the motherboard in my old 1530 is
pretty much dead.

The first thing I did was replace the Dallas chip with a new 12887.
You have to be very careful about unsoldering the pins. I have a
special soldering iron which has a bulb suction on it to allow you to
suck the solder out while it's still hot. It works very well. That
made the job quite a bit easier. Once I replaced the Dallas chip,
that removed the invalid configuration code 02, and the machine
booted up very nicely. But the HDD would freeze sometimes when I
booted up (I would shut down and reboot several times just to test it
out and make sure it was relatively consistent in its peformance.) So
essentially it was a working machine, albeit with a HDD about to go,
but it only had 1 MB Ram on it in four 256K sticks.

I replaced the four 256K sticks with the eight 1MB sticks from my old
1530.

Now this is important for 1530 users. There is a jumper (called
either J3 or J5), which is right next to the RAM stick area of the
board. The jumper pins must be JUMPED (connected) of you are using
only four sticks of memory. They must be UNJUMPED (disconnected) if
you use all eight slots for memory. You will find the diagram for
this at the end of the 1500 Series Assembly/Disassembly Manual I
uploaded. The diagram for loading memory into the 1520 is there also.

I pulled the jumper pin and installed the eight sticks of 1MB memory,
and this did the trick. I rebooted and the machine came back with the
full 8MB of memory.

Now I had to figure out if I could put my LCD display on this
machine.....

The manuals also provide the information for this. This is important
whether you have a 1520 or 1530. This will apply to both systems. The
power supply voltages needed for the monochrome, gas plasma, and LCD
displays ARE ALL DIFFERENT. In other words, any time you change the
type of display, YOU MUST CHANGE THE DC/DC CONVERTER WITH IT in order
to properly supply the new display with the right voltage and
current. In addition, each type of display will likely require its
own video card to go with it. The monochrome ROM/VIDEO card is the
standard. The gas plasma ROM/VIDEO card might be the same one, but
one of the ROM slots is occupied. I don't know if this was a chip
specifically needed for the gas plasma, but I think it is, because of
the coding on the chip. But the two cards do look different to me.
The important thing is the LCD video card is completely different.
There are no ROM slots for use by the operater on the LCD Video card
BTW. There is only one ROM chip slot that is used specifically for
the LCD circuitry.

After reading the manuals on this, I took my old LCD display with its
own video card and the old DC/DC converter my old computer had, and
transferred them into the new machine. Voila! It worked perfectly.
Now I had LCD display and 8 MB on a working machine. So there is no
need to adjust BIOD code to do this, which was one fear that I had.

The only thing left was the HDD. I took the BIOS ROM chips and
altered the HDD tables as per Shawn's protocol and put in the CFS420A
that I had been saving into the machine (I went ahead and had fdisked
and formatted it beforehand on my old pentium I use for burning the
chips.), and then burned the new chips and put them into place.

And the machine came up beautifully. I now have a fully functioning
1530 with LCD screen, 8 MB RAM, and 460 MB HDD space.

Ahhhh......Life is good. :)

Sorry to hear about that,

As to the compact flash drive question, I'll have to defer to Shawn,
of course, to answer that question. he's the one working on that. In
any case, do you have the capability to burn your own EPROMS? It's
easier to obtain one of the newer Conner drives out in the world. I
have a couple of CP30174E's for future use for example. It just
requires burning the new chips for it.

BTW that's the only way you're going to change the BIOS at all. Your
original chips that you have in your machine cannot be flashed once
they have been burned. Those are permanent. If you want to change
your BIOS, it will require new chips, of which EPROMS are your best
choice, since they can be easily erased and used again.

One way to make it easier to replace a multipin chip like that if you
don't plan to use it again is to use some small cutters and cut each pin
off the chip the take out the dead chip then you can unsolder one pin at
a time.

Good job by the way.

Thanks! Len,

     And your suggestion is certainly a good one for IC's that aren't
going to be reused.

     I considered that, but the way the Dallas chip is constructed,
it's really is impossible to get underneath the chip to the pins in
order to clip them. Besides, I'm trying to save them for the
conversion process to use an external battery on the chip, which it
looks like may be necessary on the 1520's. If you put a new 12887 on
a 1520, the BIOS code is too primitive and it will recognize the new
chip as uninitialized and give the "Time of Day stopped" message.
Then it will ask for the BIOS password (There is none, I believe. I
think the GRiD engineers deleted that out of the original Phoenix
BIOS code). When you try to enter a password, the computer responds
only with "Incorrect Password" and then forces you to reboot, which
then just loops uselessly through the whole thing again. I am
investigating trying to change the BIOS code for that problem, but I
won't solve that anytime soon.

The BIOS code of the 1530 gets past that, and will give the
same "Time of Day stopped" message when you have a new uninitallized
RTC chip in it, but it will go ahead and boot up and allow you to
change the time and date afterwards.

Hey Phil.
Congrats on the 1530!  Glad to know its working well.

Your information about the proper power supply with
the proper display is exctly correct.  I plan to
include that information when (if) I write up the
procedure in Word.

As far as the 1550, I would try removing the hard
drive and seeing if that makes a difference.  It is
possible that the hard drive is pulling down one or
two of the voltages.
Good luck,

Hello Celso.
If you want the CP3024 drive, I can buy it and ship it
to you just as I did with the display.  But, do you
really want to do that?
The CP3024's is about 17 years old.  I am guessing,
but I think you might get 3 to 5 years maximum of use
from it.
If you want to keep a hard disk drive in the Grid, I
would recommed getting a newer model than the Conner.

I am still working on getting a compact flash to boot.
 I was out of town this week.  I might have some time
during the weekend to work on it.

Before I left, I was able to get my P-III 633 MHz to
boot to MSDOS 6.22 from an 8 MB compact flash.  I will
keep you all posted.

Celso,
    I'm sure either Shawn or I could burn you some new EPROMS for you
if you can't do it. If this is a standard 1520, then do me a favor
and look on your BIOS chips and tell me what the checksum counts on
them are. My 1520 has the checksums of 2F00 for the odd and 7A00 for
the even. If your checksums are the same, chances are we have the
same BIOS chips in our units. If so, I could burn you some new chips
with the CP30714E HDD included in the table, and I don't mind selling
you one of them. Of course, they're old HDD's, too, but not quite as
old as the CP3024's, so they may last a little longer. Plus, you'll
get 170 MB out of it.

If your checksums are different, I or Shawn would have to get a copy
of your BIOS file to make the necessary adjustments to the file and
burn some new chips for you. You could use Michael B.'s utility that
copies it into a file and you could just email it to me or Shawn.
Well, even if our BIOS's match, you could still do that. :D

Anyway, let either me or Shawn know.

Hey Phil,
Celso already emailed me his BIOS files.  They are
different.  They are so different, it almost seems as
if they were made by a different manufacturer.
The hard drive table is the same.  I'll email you
merged file off list.
The Phoenix BIOS information at the beginning of the
file is changed, but for only one chip.
At around address $6350, there is a text string that
says "GRiD Systems Corpirrus LogicPR"
It's almost as if somebody mixed a Cirrus Logic and
Grid BIOS file.
I burned it to EPROM and tried to get my 1520 to boot.
 My 1520 did not boot.
I'll email it to you.

Hey, Shawn,
    I looked at the files you sent me. Actually they aren't that
different, I think, at least from the code perspective. Somebody has
somehow altered this before and gotten the computer to accept the new
checksums that resulted. A checksum of 4C73 is defintely weird, since
all checksums that Grid made on these chips appear to always end with
00. My side question then is how do you get the computer to accept a
new checksum?

In any case, I don't think they changed any code, just some of the
identifying data.

Anyway, back on track, I have adjusted the BIOS file to accept the 
CP30174E HDD and burned two new chips for it. The two new chips and
the HDD are ready to go.

On another note, if you tried to boot your 1520 with chips burned
with his BIOS, I'll bet you got an error beep code which came back as
1 beep, 1 beep, 4 beeps. If you did, that's the beep error code for
bad BIOS which needs to be replaced, which happened because the
checksum was incorrect.

Phil,
In your other email you asked how to get get the
computer to accept a new checksum.  My short answer
is, "I don't know."
The long answer is before Celso sent me the files, the
checksums were soemthing like 00E0 or FB00, or
something similar to that.  Those values can be
anywhere.
Celso's BIOS has one that is 4C73.  That's a unique
string of numbers and *should* be easy to find.
I spent a few minutes looking and I did not find it. 
I did not try any big Endian/little Endian
combinations.  I didn't spend much time on it.

One other piece of trivia.  I have 2 different
versions of motherboards.  The older version is the
one with the Tadiran battery backing up the clock
(Versions AE and AR).  The newer version has the
Dallas RTC (version C).  The newer BIOS (7A00 & 2F00)
will work in the older AND newer motherboards, but
older BIOS (DE00 & 0B00) will not work in the newer
motherboards.

More trivia: In the 1520, the DC20W4P-XXX power supply
(DC-DC converter, actually) will only power the LCD
display.
The DC38W4P-XXX will only power the flourescent amber
display.
I am guessing that the "20W" indicates 20 watts and
the "38W" indicates 38 watts.

Shawn,
     You're right about the wattage. I remember Grid actually telling me about that when I upgraded my display fifteen years ago. Although as I remember it, I thought it was the other way around, where the higher wattage was required by the LCD, but I'm probably wrong on that.

Anyway, I have a CP30174E and Two freshly burned EPROMS for Celso with this HDD in the tables made from his old BIOS files. I figure about $20 ought to do it, considering. let me know if Celso would like to have them.

All,
Sorry for all of the confusion!  It's all my all my
fault.  The person who emailed the files to me was a
member that goes by the name "Zentaro."  
For some reason, I thought that Celso emailed me the
files.
Again, sorry for the confusion.

Well, so much for those chips (grin), oh well..... I'll just erase
them and prep them for the next burn. :D

Celso, there is a file that Michael Brutman has on his website that
will download your BIOS code into a file. If you could, get hold of
that utility and download your BIOS into a file and upload it to the
file section here on the forum. I can then adjust it accordingly for
the CP30174E drive and then burn you some new chips. Then I can send
the HDD and the new chips to you. I can also make sure it gets
packed very, very well so it will survive the trip.

Phil

Subject: Well, now to my 1520.............

Well, I've finally gotten my 1520 up and running, sort of. I went ahead
and did the external battery thing on the old Dallas chip (1287) and
removed the 12887 I had in there with which I had replaced the original
RTC chip. I think that maybe the 12887 itself may be the problem
instead of just the BIOS now. Although it's supposed to be the
replacement for the 1287, it may be different enough that the 1520 just
doesn't like it. Anyway, I replaced it back with the old Dallas 1287
and a new external battery and it fired right up.

Unfortunately, I have another problem. The computer saw the 162 MB
CP30174E HDD okay. I just can't do anything with it. At first I could't
load any OS except Grid DOS 3.3, as it just said "Missing Operating
System" if I tried any other OS, and then would hang up. So I could
only load the GRiD DOS 3.3 okay. FDISK gave me the full 162 MB on the
HDD. But the FORMAT.COM will not work. It will only attempt to format
up to 32 MB and then it stops and hangs, forcing me to reboot, and the
HDD is still not formatted correctly, and I can't use any other
FORMAT.COM from higher DOS versions because they will refuse to run
under a different DOS version.

I've tried the orginal MSDOS 6.22 boot disk, which will get through on
a cold boot, but it won't setup because the HDD is not ready, and when
I boot out of it into the A: prompt, the keyboard goes all screwy and
won't type correctly. For example the number pad turns on, and I can't
get it to turn off. Letters will suddenly repeat without being queued
to do so. I'm forced to reboot and end up back where I started.

So I did it the drastic way. I took the HDD out, formatted it on my old
P1 machine and loaded MSDOS 6.22 on it as a bootable drive and put it
back into the 1520. But now the XMS driver won't load because it canb't
find EMS, and himem.sys didn't work either, loading DOS into low
memory, which just locked up everything.

I'm just not familiar enough with the 286 machine like I am with the
1530. Do I need to load an earlier version of DOS? it looks like MSDOS
6 just won't cut it.

I know you got through this somehow, Shawn. What do you suggest?

Thanks,

Phil

Wow, Phil.  
You're in uncharted waters for me.

I installed MSDOS 6.22 from floppy onto my 1520.  My
hard drive is the CFS420 (CFA320).

I could understand DOS 3.3 not supporting the larger
hard drive.  However, I don't know why you're getting
the Drive Not Ready error.

I'll put some though on it and I'll let you know if I
come up with any ideas.

When do you get the Not Ready error?  If you boot from
floppy and then go to C:, do you get the error then? 
Or, do you get it only when you attempt a format?
Thanks,
-Shawn

Shawn,

I'm not getting a drive not ready error. The problem is that 6.22
will load into the HDD. But when I try to boot up, the computer does
not recognize any extended memory manager. What this does is shut
down all memory above the 640K limit. If the extended memory manager
is not there, Himem cannot work because there is no high memory for
it to work on. It's not recognized. With no extended memory, nothing
will work because there's not enough memory to do anything. The
program used in 386 mode is the EMM386.sys file, but I can't use that
in a 286 machine, so I don't know how it is working in your machine.
I think I will have to try a different hard drive and see if it does
the same thing.

Phil

Subject: Re: Well, now to my 1520.............

Well, I think things are worse than I thought. I have reloaded all
the original equipment back into the 1520, and I still get the same
problem. I put in the original BIOS CHips. I put in my old CP3044
from before my upgrade, and I put in the original memory.

What happenes is that Himem tries to load ver. 3.10, and seems to do
so but then comes the message:

ERROR: No extended memory found

After that, it says Himem could not be loaded because the upper
memory could not be found.

I have no idea where this is coming from. I am using all the original
equipment inlcuding a CP3044 that works perfectly on my old 1530. And
the funny thing is the HDD seems to be working on the 1520 just fine.
I just don't have any memory to work with. I have no idea what's
going on here.....I fear the problem is another bad motherboard,
unless somebody out there has some idea...

Phil

Phil,
What about putting 

device=himem.sys
DOS=HIGH, UMB

in the config.sys file?

The DOS=HIGH, UMB loads DOS in the high memory area. 
The UMB portion signifies Upper Memory Blocks.  I
don't know what UMB's are, but I remember that they're
good.

I might be wrong, though.

UMB stands for Upper Memory Block. The UMB consists of addresses 0AOOOOh to 0FFFFFh. The instruction DOS=HIGH is already there in the config.sys file. But that's not where the problem is. DOS cannot even be put into the UMB until the upper memory is even recognized as existing. The computer find it. I put in a good HDD that would load fine in another computer, but wouldn't load properly into this one because of this problem. The problem is not in the config.sys file instructions. It's before that

  Phil,
  What about putting

  device=himem.sys
  DOS=HIGH, UMB

  in the config.sys file?

  The DOS=HIGH, UMB loads DOS in the high memory area.
  The UMB portion signifies Upper Memory Blocks. I
  don't know what UMB's are, but I remember that they're
  good.

Yes it, does. But that doesn't mean it knows what to do with it just from that. The memory is only being verified as physically being there and checking out as working. It doesn't mean the operating system sees it.

 Unfortunately I'm going to be away from home until
June so I can't check my 1520 boot-disk or archives. I
had 8MB recognised. IIRC there was an option for
expanded or extended memory in the set-up program. You
had to select the extended option and then have the
EMM installed by your autoexec.bat. Can't remember
whether or not the name was EMM386 or other.

From: "jeriddian"
Subject: Re: Well, now to my 1520.............

Thanks, Lawrence,
     I hope you're right. The problem I get is that when I try to
boot the installed MSDOS 6.22, I get the following message:

"XMS driver version 3.10 - cannot recognize any extended memory.
HIMEM.SYS not loaded."

>From my research, this could be bad or mismatched memory chips. I've
switched those out and still get the same problem. So if it is a
hardware problem, it's on the motherboard itself, in which case I'm
toast. But if it's the option you are talking about, that may be the
trick that does it. However, when I install MSDOS 6.22 (and I have
the original microsoft disks for that too), It doesn't give me any
such option.

The memory boot check of the RAM is rough and ready check of the
memory only. HIMEM actually writes 0FFh and zeroes to the memory in
order to check it out, and will spot hardware problems that the
initial memory check does not. But when I change out the memory
sticks, it doesn't fix the problem which tells me it's not the RAM.
However, when I load Grid DOS 3.3 from disk, it loads fine, but now
it's starting to get erratic, and I'm worried that the motherboard
itself is the problem after all.

I'm not sure EMM386.exe is a problem, but I don't think so. It
doesn't try to load until after HIMEM.SYS does. Himem must come
before EMM386 as a listed driver in the config.sys file. In fact
himem.sys must come first before any driver at all (except setver.sys
apparently) I hope you can find this setup option, because I've
pretty much exhausted my other options at this point.

 I believe it was one of the files in the grid15xx.zip from Tandy.
I can't recall whether I used DOS 5 or 6.xx. It did allow me to use
Win 3.(1 ?) however. Non-protected version IIRC.

Subject: Re: Well, now to my 1520.............

Well, DOH!.......When in doubt, READ THE DIRECTIONS! (ugh, I'm brain
dead.)

Granted, it's hidden amongst everything else, but all I had to do was
read the Technical Manual. But it's there in the operation of the
80C286 processor on page 2-9 which says that the memory above 640K is
seen on a 1520 as either all extended or all expanded. You have to
use the MODE command to switch between them, which is what I did and
Himem worked perfectly. The command is MODE MEM=EXT. That was all I
had to do. Jeez!

Unfortunately, I'm still having a problem with the computer in that
after a certain amount of time, it seems to want to just freeze and
does nothing and I am forced to reboot, although it's definitely
better than it was. Part of HIMEM's switches is that you can set the
maximum EXT mem and possibly release the rest for EMS (i.e.
DEVICE=HIMEM /MAX=384K), but I'm not yet sure that's allowable in
HIMEM ver 3.10, or even allowable in the GRiD's 286 hardware
architecture. But since it is offered, I would think it likely
(unless it was meant for the EMS MODE only). I have to look that one
up. If so, then I would have to load the EMM driver. I'm also still
not sure if I can use the EMM386.SYS. The Grid 15XX tools that
Charles redirected me to does have an EMM.SYS that may be more
appropriate.

Onward!

Well, more info on EMM386.SYS

As I suspected, my research shows that EMM386 is not supposed to be
used on processors below the 386. This tells me that the 1520 was
designed to run its upper memory completely as extended or completely
as expanded memory, but a mix of both is only possible with the 386
processor and higher (at least on the GRiD). I cannot find a switch 
for HIMEM in DOS that will allow me to assign a certain amount of
memory to extended memory. So it looks like I'm stuck with what I've
got, which is okay actually. Now I got to figute out what's hanging
the darn thing......

Subject: Re: Well, now to my 1520.............

To Lawrence,
      Management of memory in an 80286 appears to be a lot more
trickier when it came to managing the memory above 640K. The 80386
comes with sophisticated hardware alredy inside the chip to do the
memory managing whereas the 80286 is dependent on external hardware
and software to do that. I am still getting freeze ups of my 1520
after a period of time, and I'm sure it's because the memory is not
being properly managed.

You said that you are running Windows 3.11 on your machine. I wonder
if you are running your memeory under extended or expanded memory?
(or does it matter once you install Windows?) I was wondering if I
could get a look at your config.sys and autoexec.bat files? That
might give me a clue as how to configure this beast properly. I've
never worked on 286 machines as I jumped directly from a Z80 to a
386, so this is a little new to me.

I've looked at using QRAM or QEXT, but I am not sure if that will do
the trick. I would sure appreciate the help. Thanks.

Phil

Alrighty, the clock battery in a friend's 1520 died, so I replaced it
by tearing it all apart, and soldering a new one in - it boots, says
to set the time (press f1 to continue), then a message comes up in
what looks like French, showing a funny looking date, and requesting
me to enter a password.  No matter what I enter, it just reboots.

Subject: Re: 1520 problem from new user

Hi, Sp4rtikuz, I'm Phil

      You have a bit of a problem in that the computer is asking for
a password to get into the BIOS CMOS setting control program for the
computer. The problem comes in that there is no BIOS CMOS setting
control program in the boot up chip in this computer, so the computer
has nothing to which to compare any answer.

      The motherboard you have is the older version with the 146818
time chip. It may be that CMOS circuits in it didn't power up
correctly and their contents may no longer be recognized as valid by
the BIOS program. The usual cure for this is to disconnect the
battery and allow the CMOS circuits to power down. However, that may
take some time. I read in another forum where this exact problem
happened and the person in that post had to disconnect the battery
and leave it off for a full week (I guess to completely discharge any
electrical charge left), before he hooked the battery back up again,
and then he said the computer booted up properly. That may be all it
will require.

      However I think the problem may be more likely that you have a
bad hard drive. The old Conner hard drives in the 1500 series
GridCases are notorious for going out, and they are difficult to find
out in the world today. These old Gridcases will only accept six
different old style Conner Hard Drives that are hard programmed into
their BIOS code, so you would have to find one of those particular
HD's to do the job. It is possible to put in a different HD as long
as it had the same physical connection configuration for the pins (it
is the older style that was phased out in the early 1990's I think),
but to do that, you would have to burn new EPROM BIOS chips with the
hard drive tables altered to accept the new hard drive. Both Shawn
and I have done this successfully BTW. Shawn has done it with his
1520 fitting a CPS420A 430 MB HD. I've done it on 1520 and two 1530's
with the CPS420A, a CP30174E 170 MB HD (in the 1520), and a 30104H
120 MB HD. So it is doable.

     That's my take on the situation. Shawn may have a better answer
for you.

Phil

High Marion, I'm Phil

     As I understand it the 2270 is the pen based computer which can
use a pen to touch the screen to input commands. The screen is double
hinged so the screen faces up when case is closed, but you can flip
it open to reveal a keyboard. It is a 486 computer and has a quick 
change battery which can be changed when the computer is in a power
savings mode without having to restart. It probably does have a hard
drive in it, but the computer just doesn't see it right now becasue
the battery(s)are dead.

     I don't know much about this model unfortunately, and I don't
know if there is a user on the forum who does. Most of us are
familiar with the 1500 series units. However, I think the first thing
is to make sure the battery pack is good. I have a feeling the
battery pack may have to be replaced, simply because of the age of
the unit. If that battery pack is replaced, made good, or proves
good, there will likely be an internal CMOS battery that may also
have to be replaced, which is very likely to have gone bad by now, so
you may have to go inside the computer to do that. I do know that in
the Grid computers, it seems that when the CMOS battery is dead, it
affects the CMOS circuits so that the computer will not recognize the
hard drive.

Unfortunately, the hard drives in these old Grids also have a
tendency to go bad. So right now, my best suggestion is making sure
both batteries are good and then see if the computer will boot up. If
it still doesn't recognize the hard drive, then you will have to find
a replacement for it. You will have to look at it and see what it is.
It will likely be a Conner Hard drive with the old style pin
configurations. If so, they will be hard to find. You probably won't
be able to use newer styles. The BIOS will likely have hard coded
into it the particular Conner hard drives that the unit will accept
and recognize, but I would have to get a copy of the BIOS somehow to
see what those hard drives are. It is possible to put another hard
drive into it, but you may have to have new BIOS chips burned with
the parameters for the new hard drive on it so the computer will
recognize it. That would take some special equipment to so that.

Hope that helps.

Phil

It is somewhere inside the computer, probably hardwired onto the
motherboard. You would have to disassemble the computer to look for it.

From: "Kevin"
Subject: New user, Old GRiD fan, 1101 question, 1535 question

Howdy All,

I'm a long time GRiD fan but never thought to look for any GRiD
related groups until recently.  I have a handful of machines
including a gas-plasma gridcase-3 with internal floppy, a gridcase2
with lcd and still working 10mb rll hard drive+4 roms, and another
gc2 minus screen and drive. I also have two Compass 1101's and a
recently acquired 1535exp that I'm dying to get linux onto.

Now for a few questions:
On the 1535 - Unfortunately I don't have a dos disk for it. Is there
an archive of these disks as images / self-extractors anywhere? And
how about ROM's, any images floating around? I could always burn a
dos rom if an image is out there..

Is there a keyboard shortcut to turn on the backlight? I see it come
on for a second during bootup but I need to run the grid mode command
under the right dos version to turn it on.  (Perhaps setver could
trick it into running, haven't messed around with it yet)

1535 hard drive - I'd ultimately like to weasel in a compact flash
drive as a HD (wouldnt mind if I had to boot the linux kernel off a
floppy).  Unfortunately I only have an upper floppy drive. What would
it take to manually wire in an IDE connector?

and then onto the compass 1101's..
I did something extremely stupid the other day. When trying to get
apps to run I would constantly get out of space errors.  I went and
ran the initialize program thinking the o/s would be smart enough to
erase only the user area, but found out it wiped out the ENTIRE
bubble memory. The machine is toast now, doesn't even show the
awesome GRiD logo at powerup anymore.  Is there anyone out there who
could reload the bubble memory modules? I would imagine there was
some kind of procedure back in the day, booting off a GPIB floppy and
reloading them? If somebody was interested in doing this, I'd gladly
donate my second "parts" 1101 for their time. My parts 1101 had a
sticker on it saying "bad supply" when I got it, and only has 1 or 2
of the 3 bubble memories inside.  Thankfully, I got lots of pictures
of the 1101 apps running a few years ago because I have a feeling I
will never see anything other than boot errors on the machine.

Hello, Kevein!

Welcome to the group.  You asked a lot of questions. 
Hopefully, I can answer one or two.
I'm going to do some snipping of your original email.

Yes.  Go here:
http://tech.groups.yahoo.com/group/RuGRiD-Laptop/files/

Look for DOS33.exe.  It is a DOS executable that
should install MSDOS 3.3.  It says that the file is
for a 1520 but it should work on your 1535.

>And how about ROM's, any images floating around? I

I don't have one nor do I know of any for the 1535. 
My GC2 (or is it 3?) has one that I haven't
transferring from the chips.

Are you still talking about the 1535?  I don't think
setver will do it.  I believe MODE is the command from
DOS.  I don't have the 1535 so I don't know for sure. 
Look to see if you have a program called conf15XX.exe.
 That is what I use to turn my backlight on off.
specifically, I type (with the disk in the drive)
'conf1520.exe backlite=on' and it works.
You might try 'mode backlite=on' and see if it does
anything.

heh, heh, heh...if were only so easy...
It's a little more than "weaseling."
The 15XX series GRiD's have the hard drive types
loaded in a table that's burning into BIOS EPROMS.  If
the hard drive isn't in the table, the computer won't
boot from the hard drive.
Phil (another member of the group) and I (with help
from Mike) have gotten our 1520's to boot from 120 MB
Conner drives by patching the BIOS chips.  I want to
get mine to be able to boot from CF as well, but
that's another project.
The instructions on modifying the BIOS files are in
the Files area as well.  I think I titled it "1520
Hard Drive Reprogramming Instructions.txt"
I would love to run Linux as well.  I have a version
of Mimux that is summpsed to run on a 286.  I'll get a
round to it one day...

You mentioned "wiring in an IDE connector."  If your
1535 doesn't even have an IDE port, then you've got a
"long row to hoe."  Good luck.

Sorry, man.  I don't have the ability.

You mentioned GPIB.  I have 2 GPIB interface pods for
the 15XX Grids.  I haven't powered them up yet. 
Another project for when I have more time.

I hope this help.

Subject: Re: New user, Old GRiD fan, 1101 question, 1535 question

Hey Guys,

I hit up the archives and RTFM'ed all the PDF's and grabbed the other
relevant goodies.  The backlight control works with the mode command
so I have now seen the light :)  What I meant before was using setver
to trick the mode.exe to run under a different version of ms-dos, but
now since I have 3.3 going, that is no longer as relevant.  Oh, and
it was mode2.exe I had to use, the one on the 3.3 disk gave some
error saying the argument "back" was not recognized or something.

As far as the roms go, my GC2 has 4 roms in it, interid and possibly
an ms-dos bootable rom, though the one time I had the HD out, it
didnt look like it booted off rom.  I should take them out some time
and back them up as hex files.  One thing I do notice is once I put
the roms in that machine, I no longer can run disk utilities like
norton disk doctor, defrag, etc.  So that's something to keep in mind
if you ever need to do any disk maintenence.

Now in the hard drive world - In my initial look inside the 1535, I
didn't see any IDE connectors, laptop or desktop size, and
the "backplane" thing for the floppy looked like it only works with
one drive.  I'm not sure if IDE connects via a different backplane on
the same connections as the floppy, or maybe thru another connector I
noticed that has nothing plugged into it.  Perhaps I should take some
pix.  While on the subject of drives, I did find a Conner CP2044PK in
my junkbin, is that by chance one of the "blessed" drives that the
bios likes? Were the orig drives that came in there 3.5" or 2.5"?

I also found an intel 25mhz 387 in my junkbin.  When I popped it in,
the 1535 turns on and gets stuck at the point where the backlight
comes on for a second. No post beeps or anything. I'll have to verify
the copro as functional on another machine, but is it possible i'm
missing something like a jumper setting to get a copro to work?  I
also found some NEC V30's while searching the junkbin, which I will
try in the GC2 and report back if they work or not.  The V30's give
you a speed boost in certain computational situations and supposedly
have a z80 emulation mode that has CP/M potential.


Probably the most important project I have on the list of things to
go is boosting the 2mb to 8mb. I need at least 4 to get a linux
kernel to work.  I'm gonna see if I can somehow score some millmax
pins as samples, though 30*8=240, which is probably pushing the
sample limit. The other options are to salvage the ones off the
existing chips or maybe take an old simm socket and bust out all the
metal fingers and solder them on one by one. Not a job I look forward
to.  If only they had spaced the SIPPS farther apart, then you could
just pop a simm and simm socket in there.. I think in the pdf's i saw
the 4mb configuration is using every other socket on a 386 so perhaps
the socket idea could work if you only needed 4mb.

Eventually I'd like to look into overclocking the 1535, as power
consumption isn't a major concern, but first I've gotta get a semi-
decent amount of ram in there.

Kevin,
I'm glad to know that the backlight control using
'mode' worked.
I've never found a use for setver.  As I understand
it, it's used to "fool" other programs that your
actually using an older version of MS-DOS.  Everytime
I've seen setver tried, the program usually returns
"Incorrect DOS version."  I've never found any use for
it and I take it out of config.sys whenever I see it.

I have the 1535 BIOS file, but it's on another hard

Hey, Shawn, Kevin,

You're right, Shawn. the manuals did not fit into the files section,
which of course is why we loaded them separately on your own ftp
server. However, the 1535 owner's manual is indeed in the files
section and it is complete. It's just divided into seven sections.
But it is all there for you, Kevin.

You're also right in the the CP2044 is not supported. it's not in the
hard drive table in the ROM.

Another note to consider, Kevin. I don't think you will be able to
fit an IDE connector into the computer for the simple reason that IDE
was not insituted into the technology yet (or was actually just about
to be instituted.) These hard drives are NOT IDE driven. They are MFM
RLL(modulated frequency modulation), which is the old technology that
was superceded by IDE. If I am not mistaken, you have to use old MFM
hard drives like the old Conners, which is also may be one reason I
think the configuration of the positioning of the HD pins was
changed, in order to distinguish between the two. You may be able to 
plug an IDE HD and get it to work in an old MFM system like the Grid,
but I'm not sure. But the computer's system link to the hard drive is
not IDE.

BTW, I also am looking for the 1 MB SIPP's, if you run into any
spares. The problem is that I would like to have the 1 MB x 3 as they
tend to be low profile. The 1 MB x 9 tend to be a little to high to
fit into the space provided for the memory.

Phil

Subject: Old files and programs

Shawn;
 Jeriddian has been very patient in waiting for a
response to his request for my old Grid files. I've
put together a folder I've named Gridcase of the 15xx
ones. Some of them might be duplicates in the Files
section but I didn't include obvious ones or those
I've placed in the "Files" before. They obviously need
winnowing. There are subfolders. It appears that Yahoo
groups only accept files. Could I set up a Gridcase
folder and then make subfolders to upload them to ? I
don't know what permissions members have regarding
this. The duplicates could gradually be deleted.

Subject: Re: New user, Old GRiD fan, 1101 question, 1535 question

Hi Phil,

Now things are starting to make a bit more sense. Given the vintage
of the machine, I should have known there wouldn't be IDE in there..
my GC2 has an ancient 10mb RLL drive, which is the only RLL drive I
ever dealt with in my life.. my XT's and first 386, not to mention my
atari mega ST4 all used gigantor sleazgate MFM drives (love the sound
of those things, but they're monsters!)  So with that in mind, I
think I'm going to totally shy away from hard drives for now and get
a single floppy based linux distro going on there.. I remember one
called "toms root/boot" that was a pretty well featured linux that
ran off a single floppy disk, though the floppy was formatted in a
bizarre 1.7mb format, using tighter tracks or something.  My grid
read the toms disk but choked at one point when it didnt see 4mb ram..

Good point with the 3 vs 9 chip simms/sipps. I'm sure I have some of
each laying around in my collection of ram.  I'll have to setup a
computer and test out the stuff in my junkbin.  I did get a makeshift
386 going and that 387 copro i have must be junk because the 386
board also did not make any post code beeps or anything.  Perhaps the
magic blue smoke that makes the chip work escaped over the years
while it sat in my junkbin :)

As far as pins go, the connection for the 10mb RLL in my GC2 looks 
similar to a floppy drive 36-pin connection but naturally has very
different signals, not to mention the 5v and 12v lines go thru the
cable as well.

For memory I may try salvaging the pins off the existing 256k sipps,
or try my idea of salvaging the metal of simm sockets.  Mill-max only
seemed to be game for sending me 50 pins as free samples and a
minimum order of 500 would be around 52$.  I guess that's plan-c if
my first two ideas don't prove useful.

How large are those CP3044/et al. drives? the drive in my GC2 is
about the size of a double-bay 3.5" drove.

Ahh! don't you know you have to hide cool stuff like your computer
collections from the wife? My collection is a bit over 100 computers
at the moment, though I try to limit the number that I have laying
out in the open so she doesn't complain :)

And speaking of compact flash, now knowing IDE is out of the
question, I wonder about those old adapters that would take something
like a smartmedia memory card and use the floppy drive to read it.  A
carefully crafted driver might be able to make use of such a thing.
I laughed at those things when I first saw them, but i'm not laughing
anymore...

Yep, got it and made the disk using a W98 box.  The first 3 disks I
tried making didn't read back in linux, but the fourth was a charm.  I
wanted to make a raw img backup of the disk so I could create future
ones without having to resort to W98. With the raw image file you can
make more disks using the cat command under linux, or rawwrite.exe in

PS. I found someone on ebay who is trying to sell about seven or

I tried taking the pins from a DIP socket, removing
them from the plastic, then soldering the pins to
SIMMs.  I did not go well.
The metal of socket pins was more flat than round. 
This made it hard to insert into the motherboard. 
Secondly, the pins from the socket were thinner.  This
made it easy to bend the pin trying to insert it into
the motherboard.
Thirdly, this is little room for error in soldering
the pin to the SIMM.  If you are a few mils off to the
left or the right, the pin won't line up with the
hole.
Even with the above problems, I managed to assemble
one.  Then I ran into the fourth problem: the SIMM
memory I used was physically too large to fit.  The
height of the SIMM prevented the cover from going onto
my 1520.  And, module was too long on the right side. 
It extended into the LED area and would not fit.

That was my experience.  I hope your goes more
smoothly.  I have not heard of Mill-max.  I'll have to
look them up and see what they have to offer.

Thanks,
-Shawn

Phil started this, and it raised a red flag in my
head, but I let it go at the time.  The interface to
the hard drive on the 1535 *is* IDE.  The drives that
the 1535 "talk" to are IDE drives.
It sounds like whoever originally ordered your 1535
from Grid ordered it without a hard drive.  So, Grid
did not install the interface board that connects the
motherboard to the hard drive.  That would explain why
you don't see an IDE connector inside your computer.

That sounds complex.  As you may know, I'm using
Compact Flash on the IDE port because the interface to
compact flash is IDE.  No special drivers are needed. 
Theoretically, I should be able to "plug and play." 
But, nothing ever works according to theory.

Lawrence,
It took me while to understand what you were asking. 
I think I understand now.
Why do you do this:  ftp the folder and subfolder to
me.  I'll go through it, delete duplicates, merge it
into one folder, then I'll move it into the Files
area.
The ftp site is ftp://shawnerz.homelinux.org
Login with 'griduser' as the name and password
'griduser.'
There is a folder called lawrence.  Feel free to
upload it all there.

Kevin:
Just about all of the 1500 series Grid manuals are
located there.  The 1535 manual is in the Files
section of the Yahoo group, but (as Phil said
yesterday) there wasn't enough room for the 1520 and
1530 repair manuals.  So, they are loaded on my home
Linux box.

Phil: 
If you want Lawrence's "raw" files, you can ftp them
from my Linux bax any time after Lawrence uploads
them.  If you want to wait, I'll put them in the Files
section of the Yahoo group when I have time to parse
them.

Thanks, Lawrence.

I'm kind of confused about that.  Most BIOSes does not use the Intel
reserved instructions that NEC overloaded to implement the 8080 mode.
 This sounds more like a bad V30, wrong clock speed, incorrect
placement in the socket, etc.

If you dump the BIOS to a file we should be able to look for the known
bad opcodes and prove this, but it is highly unlikely.

Subject: Creating SIPP's from SIMM's

Shawn,

I actually had thought about taking the pins from a 256K SIPP and
soldering them onto a 1 MB SIMM. I took the thirty pins off of one
such 256K SIPP. It will destroy the SIPP if you do that and if you
are not very careful. But that would give you the right type of pins
you would need. I have bought a couple of 40 pin DIP sockets that I
glued together end to end. I had thought to position the pins in the
DIP sockets and fit the SIMM onto the pins and solder them in place.
The DIP socket would keep them properly positioned. However, I
haven't gotten that far as to actually trying this last part. I still
have the pins sitting on my antistatic mat.

But this is a lot of involved work and very tedious. It would be
better if there were an automated way to convert SIMM's to SIPP's. I
know that the SIMM sockets won't work because the distance between
the pins on the GRid board is 0.2 inches, and the width of the
sockets is 0.3 inches. So we really have no choice but to use real
SIPP's.

On one of my machines, I was able to secure a matched set of eight
1MB SIPPS, but they were 9 chip sticks and they are too tall by about
three thirty-secondths of an inch. I would have to cut out a section
of the plastic face plate cover which fits around the keyboard, and
then find a way to affix it back so it sits above the level of the
face plate itself so that it will stick up above the normal level of
the face plate cover. I could do it as there is room for it without
preventing the screen from latching down in the closed position. But
I really don't want to cut up the cover.

On one of my 1520 machines, I have four 1 MB SIPPS which are three
chip sticks and have the right height, but they had wings on the
sides which made them too wide. I made sure that that none of the
integrated circuitry lines were in the wings and then I used a dremel
tool and a cutoff wheel to carefully cut off the wings. It worked 
just fine and now the sticks will fit in my 1520.

Still, it is just easier to try and find the SIPP's out there, rare
as they are. if you are going to solder pins on SIPP's they have to
be the rounded ones, and not the flat type you usually see on DIP
sockets. Otherwise they aren't stiff enough to position and press
into place on the board.

This si the extent of my experimentation with this.

Phil

haha Kevin actually


I got the millmax samples already. they are extremely rugged, but I
think the pin diameter is going to be too large. I was concerned with
the socket fitting the width of the board and overlooked the fact
that the pin diameter is .040"

It will take some skill to get stuff to line up, no doubt. You could
always use an old motherboard with the simm socket removed as a
template for holding the pins straight while soldering them.  I agree
socket pins are probably too wimpy, but I have seen some
bifurcated "test points" that could possibly be soldered right onto
the pad on one side of the board (assuming the pads have plated thru
holes so which side you use doesn't matter).  They would certainly be
a ton cheaper in quantity than the millmax stuff I just got.

So perhaps there is hope for a drive or CF in the future :)
It looks like my 1535 was a ordered as a stripped down model ; it has
no modem, no copro, no roms, and only 1 floppy, so lack of an IDE
backplane or whatever it's officially called doesn't surprise me.

That floppy drive to smartmedia adapter thing sounded real scary to
me since it actually used the drive-head and faked-out being a disk
somehow. If it worked without drivers that would be amazing, but it's
more likely that it used some crazy custom software under winblows

cat is infinitely handy in the unix world..
in the case of dumping a raw file to a disk, I just do a

or to read in the disk,

cat /dev/fd0 >disk.img

Purists probably would frown on doing that and say you should do a:

dd if=disk.img of=/dev/fd0 bs=1024   #or something similar

And don't forget you can use cat as an entry-only "text editor"

$ cat >file.txt
this is a test file

Wow, now you got me wondering... I went and checked wiki and found
this:

http://en.wikipedia.org/wiki/Advanced_Technology_Attachment

which mentions IDE stems from around 1986.  That's a surprise to me,
as my first IDE drive experience was probably around 1994, when we
replaced our twin 40meg MFM drives with a seemingly fast quantum 250
meg IDE drive.  I was disappointed that I couldn't run low level MFM
utilities like spinrite anymore.  That quantum was a horrible drive
BTW - it would always stop everything and do this "thermal
recalibration", which would kill any hope you had of doing anything
with realtime video or audio to/from the hard drive.  That noise was
like the death knell to me, and I remember hearing it in several
computer scenes of movies in the 90s.

Shawn,

I been in conatact with LAwrence and he's puzzled as to why he was 
temporarily banned. I informed it was about the way he was uploading
the files. Anyway, he just wants to communicate with you so if you
could lift his ban, you can both communicate about how to do the file
uploading. Thanks.

Phil (and Lawrence).
I responded with two emails to you Lawrence on
Thursday.  I used the above email address.
I let you know what was going on with the "STOP THE
PAIN" email.  Then I sent a second email to the above
email address.  In both emails, I let you know that is
wasn't anything personal.  I just needed to stop the
new email notificiations.
Shortly after the second email, I sent an Invitiation
to re-join the group.  Again, all of that happened on
Thursday.
I will say that it's odd that Yahoo doesn't show your
invitiation as a Pending event.  It doesn't show you
as a member, either.  Perhaps it is waiting for you to
respond before it adds you to the Pending list.

But, you're welcome back at any time, Lawrenece.
Thanks,
-Shawn

Subject: 1535 / built in IDE?

I took a look inside my 1535, there are two connectors, P9A/P9B that
appear to be for the floppy drive(s).  Behind that is another
connector, P8, a similar AMP type connector and it just happens to be a
40 pinner.  There is nothing plugged into it. Is it possible that could
be the IDE connection and it just used a small adapter cable? I could
probably get in there with a logic probe and see if the pinout
resembles IDE.  Norton SI listed some jibber-jabber saying there was a
drive controller, but I'm not sure if it always says that.

Hi Paul,

There's a util program, rawrite.exe that comes with some linux
distributions. I've used it under XP for writing disk images to
1.44's.  I think it supports other disk formats as well, but of
course you need a raw image file to use it.

I keep a W98 p3/500 machine with an ancient full-height 5.25" drive
in it for reading/writing old disks like cp/m and other weird
formats. It's funny to hear the old drive-head noise and then
winblows starts booting up :)

Kevin hi thanks I'll look for that app, maybe the easier route, I think my drive only repsonds to 720k formatted floppies (1/2 density)

 I seem to remember 8 inch floppy disk drives back in the 70s and I used lots of apple 2s in OEM applications back in the 80s when you had to wiat for the OS to boot of a real 5inch (i think) floppy , I laugh these days when I think of what we tried to do in a few k of RAM and low density floppies. !  I have lots of older wartime radio equipment and audio gear here amongst the newer stuff, so I like "things" you can see hear feel and use... :-) Remember the history!  The Grid I have has some military radio systems control software on it I am anxious to get off, nice to see the grids are supported mine was not used for 5 years and apart from the clock and what I stupidly did to lock myself out it worked real fine!!!

Kevin,
Does it have 40 pins or 40 sockets?  In other words,
is it male of female?
If it's female, you might be able to plug your hard
drive directly in to the adapter board.

All,
This is odd because my 1520 responds to both 720K and
1.44M floppies.
The 1520 is built around a '286 so you'd think it
would only "see" 720K.  But, it does recognize both
floppy disks.

While we're walking down memory lane, I remember 8
inch (20.5 cm for folks outside the US) floppy disks
used to boot real IBM 3270 (not emulated) terminals.
Looking back, it seems odd to boot a dumb terminal,
but that's what we did.

It's definitely a male connector. Relatively small, perhaps a tad over
an inch wide.

btw - I fired up norton SI on an old XT with the controller card yanked
out and it did not indicate one as present, so there may be some truth
behind norton claiming my 1535 has a drive controller built in. I've
gotta do some probing and see what's up. I'll probably end up on a
neverending quest to find the female side of that amp connector

It sounds like you just need a standard IDE cable.

That AMP connector is much smaller than a standard IDE connector for
desktop or laptop drives.  I'll have to take some exact measurements,
but it looks similar to an AMPMODU System-50 series connector, Digi-Key
p/n A3212-ND, AMP p/n 104068-4.

Sorry um...  that's no standard IDE.  

Perhaps a photo of a working 1530 with arrows & circles and little paragraphs explaining what the parts are....

I think he needs the backplane board for the drives, which cables directly into the motherboard and provides the female 40 pin (2x20 0.1 inch pitch) ide connector.

Subject: Re: 1535 / built in IDE?

I think I'm dealing with a lost cause.. I broke out the logic probe and
checked out the 40 pin connection and it is definitely not organized
like an IDE connector.  I'm not sure which board is considered the
backplane, there is the one board that is on the bottom of the
computer, with the expansion port that comes out the bottom, and then
there's the board that plugs into the floppy drive itself (basically
just cables and a 74273 chip on there).  The part numbers on either
board are not listed in the 1535 manual in the file section, and the
manual gives the impression that you were supposed to have dual
floppies, floppy+hd, or hd alone.  Perhaps I have a newer ultra-cheap
single-floppy board made later on. If I was ever gonna rig up my own
ide connection, I'd really need to know what the pinouts of the two 60-
pin connectors are coming off that board with the expansion connector.
60 pins is a lot for a floppy drive connection, so perhaps the IDE is 
on there as well.

With that being said, what the heck could that 40 pin connection be
for?

I'll take some pictures of the innards later tonight.  I wish there was
a repair manual or schematic floating around out there..

Hoo-boy. I had originally intended to upload them
zipped but had problems with nested files using
WinZip. When I saw the uploader could create folders,
I decided to bite the bullet and upload them singly.
There's a box on the upload form that lets you upload
file-posting notices to the group when checked. I
specifically left it unchecked but it must not have
been enabled and the default was to send a notice for
each upload. My apologies to the forum. my intentions

Hey Phil,
Thanks for the email.
The question I have is, why hasn't Lawrence responded?
There wasn't any personal, hard feelings that went
into my decision to block him.  It was the
notificiations - and you echoed that in your email to
him.  
I've sent Lawrence 2 direct emails, cc-ed him on the
last one to you, and sent an invitation to join the
group.
I haven't heard anything back.  He's welcome to come
back at any time.

The battery pack in my 1520 no longer holds a charge and I am

Also, I am wondering if there is a specific 286 co-processor that's

For five bucks, I'm willing to buy this one on ebay (which I did) and
test that theory out myself. As to the 286 coprocessor, I am assuming
it is a 287 math coprocessor you are talking about. Be sure it is a 10
MHz chip or it may not work fast enough. There's a guy on ebay right
now selling them. Just condust a search for the 287 math coprocessor at
10 MHz.

There are two more of these (Grid #32161) in my garage if anyone wants

You do realize that if the internal ni-cads are the
originals, those batteries will not hold a charge. 
Somewhere between 3 to 5 years is all you can expect
to get out of ni-cads.
The cost of replacing the cell packs will run a few
dollars.
Good luck with your project.

Oh, absolutely Shawn,

I know the ni-cads are gone. But I am hoping to replace them with
Lithium ion units that are smaller and fit inside the original

I'd be very careful of replacing any batteries in a nicad or NMH system 
with litium.  besides different voltages, the circuitry may make you a 
nice incendiary device rather than a battery pack, since the charging 
requirements are very different between the batteries.

I won't go into anything about the possible problems because I don't 
have any idea how Grid did their charging circuits, but you should plan 
on replacing at least that part of the circuitry or looking at it 
carefully before you assume you have a working system.

Lithium batteries are prone to working fine or seeming to and then 
flamo!  Ask Sony and others how predictiable the technology is and 
you'll get an idea how much the real pro's know about them (not enough).

You are quite right, Jim

I am aware of the possible explosion possibilities of Lithium
batteries if they are overloaded past their design parmeters. It is
an issue I am still exploring trying to find an external battery pack
that will support my power hungry 120 watt VAIO laptop. My plan is to
find a Lithium battery pack system that will power the Grid, which
should be easy enough to find since they are 60 watt units, yet small
enough to fit inside the shell. I would then take the grid battery
pack and completely gut it. The only thing I want is the shell. I
don't want the circuitry at all. Then I would simply affix the new
battery pack system within the shell. I guess it would be easier to
just make a new shell, but if I'm paying five bucks for a shell, I
think that might be worth it. I ant to be able to affix it to the
Grid just like the original battery pack did.

Subject: Re: Here's an interesting find. An external battery pack.

Li ion batteries are not intrinsically safe.  Law and prudence
require them to have cut-out circuits built in that will open the
battery contacts if it gets hot or draws/supplies excessive current.
Chargers for them are tricky to build...typically using an IC
designed around the battery... and with all those precautions they
still have been known to catch on fire...a nasty hot sort of fire
that's not easy to put out.  I don't know if it's hot enough to
ignite the magnesium case but that would be REALLY interesting since
neither magnesium nor lithium fires respond well to normal fire
extinguishers.

I heard about an after market add-on battery pack for a Prius that
involved putting a giant Li ion battery in place of the spare tire.
I'm not sure I'd want that, myself.

On the other hand it looks like a pretty big box and would probably
hold sealed lead-acid or gel cells.  4AH "D" size lead acid cells
were pretty expensive the last time I bought some but barring
physical damage to the case they seem to be pretty predictable.

Subject: Re: [RuGRiD-Laptop] Re: Here's an interesting find. An external battery pack.

Anyone want to do a LiIon mod I can write up some hobyest build-ables
that will do the job. The LiIon will far outperform the NiCd but has
significantly different charging requirements, and there are some 
problems (safety-wize) wich have to be considered. 

The GRiD internal is set up to use 9 NiCd (a multiple of three is good) 
1600 mAH (9.0V low and 12.24 full) each LiIon cell will oporate in 
the same voltage range as any three NiCd cells 3.0V -> 4.2V they will 
have a lower ESR (Estimated Series Resistance) be far smaller and 
liter, better yeild and so-on.  
                 However, 
                                     since they do not leak current the cells need
to be balanced during charging, and they need to be shut off 
completely when full.  Also beware operating and storage temperatures
the more full a cell is the more likely it is to have a thermal cascade. 
(resulting in a fire).  This is a situation we have to be even more careful
about because of the magnesium case.  the GRiD could become a tiny
non-radioactive China Syndrome demonstrator....

Hay folks.  Anybody interested in running Linux on a 15XX GRiD?

1986 the 1530 could be configured with Unix and the 1520 with Minix all using a multi boot (I think it was grub) by 1990 the 386 was at full popularity, and Linux was becoming the OS to watch.  

I think we can find an old 1.X Linux and an old version of black box GUI and make it happen.

I'm hoping to run Linux on my Grid 1535. The only thing stopping me is
the fact that I only have 2mb of ram.  I'm trying to build my own SIP's
and should have 8 megs in there within a week or so, so stay tuned for
my results.  The next limiting factor will be that I have no hard drive
or hard drive interface in my 1535, so running from a floppy will be
the only way I can go from the start.

I had a single floppy version of Minix that came with one of my college
textbooks.  I'll take a look and see if I can dig it up.  The chances
of it working are probably less than average though. Not one of my old
5.25 low density atari disks has ever failed me but 3.5 HD's barely
survive a trip across the room let alone a decade :p  If I can dig it
up I'll definitely post it.

All,
I don't know about that.
OK, I found mimux and an old thread (from 2002)
between you and Lawrence.
Lawrence suggested "etlinux."  The drawback to etlinux
is in needs a 386.  So, that means the 1520's are out.
I did a search and found it here:
http://ftp.linux.it/pub/People/Rubini/etlinux/

I never played with minux.  I found the files and
loaded them on my ftp server.

I also found another OS called Contiki.  I downloaded
it a while back.  Again, I haven't tried it.  I
*think* it will run on a 286.  The organization that
sponsored Contiki had a goal to bring a cheap OS to
old computers in disadvantaged countries.

I'd be interested to know if they work.

Enjoy,

no.  he designed and wrote his own system w/o unix or minix system 
exposure.  Minix and Linux have fundamentally different algorithms for 
cpu utilization, which is at the heart of a very early argument between 
Andy Tanenbaum and Linux, which lead to the myth about Linus having 
exposure to "secrets".

I believe it is well documented elsewhere, and would look it up if 
anyone is interested.  Please email me offline if you are.

Interesting to run Linux or Minix on a 286.  both run quite well, from 
what I recall from 286 days on the AT platforms.

Bare minumum for X86 linux should be a 386sx with 4mb ram AFAIK.  You

Yeah, Kevin is on the mark with Linux.  I tried Trinux three years ago on my Grid and got an instant error about not having a 386 processor.  I wouldn't even try to run X on it if I could get it running, there's just not enough firepower in my 1520.

Minix (VERY old Minix) might run, but it looks like a lot of hassle to compile for a hobby computer when I have a lot of other ones to tend to.  I would love to have the time to find out, and best of luck to anyone who tries to find out.

I love this community and am glad all you folks are trying your best to keep these things alive and running.

There must be a port on the Grid that provides access to the bus, otherwise it could not work.

Hi Guys,

First post.

Got this beauty today, and not sure what model it is.

It doesn't have Gridcase3 on it anywhere.

Any thoughts?

Thank you.

Matt,
I think it's the first Gridcase.  I'm not sure,
though.
8088 processor.  Not sure what speed.
Sorry.  1520's are my specialty.

Judging by the screen, this looks like the GRiD Compus.
I think 
8086+8087 4.77MHz 512K with about 700K of "bubble memory" for a disk drive
Bubble memory is an interestng place between a Wang mag-core and a compact flash

It doesn't say compass on the unit. Plus

I thought the compass versions didn't have an

internal floppy drive.


I'm being to think it is a Gridcase4 based on the
screen type.


Not sure if the floppy drive is screwed up with the
boot failure.  Shouldn't it boot to the A: while
waiting for a 720k disk?

Yeah  the Compasses didn`t have the function keys on top (and had a
little more space above the keys i think)
there`s a good  cross-section of grids at..

Although ok ok i`m cheating though , just checking google-images
of "gridcase" and "gridcase compass" etc.


I was just gonna assume gridcase 3

The invalid configuration is most likely a dead CMOS battery. The
unit is old enough that battery has to be dead, and this is themost
common problem causing the hard drive failures as the CMOS which
initializes the hard drive and floppy drive in this case, I think.
You would have to open the unit up and physically replace the CMOS
battery inside the unit then see if that solves the problem.

Hello Mike and welcome to the group.
I agree with what jeriddian said, but I am wondering
why you're getting the "Diskette drive 0 seek failure"
error message.
Do you happen to have a bootable floppy in the drive
when you get this error?
If so, it could mean that the 1550 "sees" the drive,
but the drive can't read the disk.  If that's the
case, either the drive or the disk is bad.
Good luck,

Well I finally had time to look at my GRiDcase 1520 again and now that
I have added an additional 2Mb ram and made space or an easier to

the system will boot from it on it's own) I am looking to see those
two ROM sockets I have filled with something. Now I really don't know
how exactly they work but I assume you can't non-GRiD chips in there
nor can you write to those chips using the GRiD.

Could someone please elaborate on how the GRiD rom sockets work?

Is this in reference to the ROM sockets that are on the video interface card (under the little door in the keyboard cover)? it is possible that one of those chips is what you are actually booting from as drive C:\
These chips can be encoded with a bootable version of MS-DOS 3.3

Subject: Re: GRiD chips

The way the application ROM chips work is that the computer will
actually look at them as an extension of the A: Drive. So instead of
your A: drive having a capacity of 1.44 MB, when an application ROM is
in place, it will actually see a capacity of 1.568 MB, the last 128Kb
being unchangeable.

Depending on the type of video card you have, you may have room for two
of these ROM chips. If you have the standard red or amber plasma mono
color video, there is room for two application ROM chips. NOw you can
have both of the slots filled with aplication ROM's, but the computer
will only recognize one of them at a time. That's because it will only
load one of them at a time into memory. If you have the backlit LCD
display video, there will only be room for one such application ROM. If
you have the upgraded VGA LCD plasma such as I have on my 1530, there
is no room for an application ROM. That had to be sacrificed to make
room for the expanded VGA circuitry, I think.

Now these ROM chips are always 128K in size or less. 128K is the max
that can be handled by the computer. Unlike the BIOS ROM chips which
are 28 pin 2C128 types, these are 32 pin configuration chips. I forget 
the model number assigned to these chips right off hand, but the EPROM
versions of these chips are obtainable much as the EPROM ROM BIOS chips
can be obtained. They can be programmed so that they can be used. There
is a program out there specifically for programming the application ROM
chips, but unfortunately I have no idea where it is. You would have to
use an EPROM burner such as has been mentioned on this forum for
burning the EPROM ROM BIOS chips such as I and Shawn have used in order
to configure the different hard drives into the computers.

You can program these chips with pretty much anything that the computer
can run up to the 128K capacity. It can be useful because you can load
MSDOS into it and it will load and boot up the computer from a higher
section of memory and free up the other parts of memory for your other
programs. So if there is a favorite word processing program, or other
program you like to use a lot, it can be programmed onto the
application ROMs. I've looked into this some and found the EPROM chips
for sale on ebay, but haven't bought any. I still haven't found the
actual program that would configure the chips. CJ or Shawn might know
more about that.

How common are the ROM chips that GRiD came out with and how hard are

Some of the blue LCD video boards will have two available sockets.
You can actually use either 28 pin or 32 pin ROM's BTW. They can be
either 32k, 64k, or 128k EPROMS or 128k masked ROM's. You can't use
anything bigger than 128k however. The actual chips that GRID came
out are not available, unless they happen to have come with a
particular model of Grid that you have. I have a 1520 that has one
such ap-ROM with MSDOS 3.3 on it, not very useful since I use MSDOS
6.00. I do believe you must use a particular configuration model of
ROM for this purpose, but I don't have the number yet. I have to get
home and look at the chip I have. In any case, if you want to program
an ap-ROM, you still have to have a burner and the software to burn
the chip, as well as the program that actually will configure the
code for you, as best as I can tell. I still have not found that
program, however. I can burn the chips. But I haven't found the
program that will properly arrange the code for it.

Subject: Re: [RuGRiD-Laptop] Re: Here's an interesting find. An external battery pack.

Phil,
Which battery chemistry do you want to go with?  There
is Ni-Cd, Ni-MH (Nickel Metah Hydryde) and Li-Ion.
Ni-Cd (or Ni-Cad) is by far the easiest, simplest, and
least expensive option.  With new Ni-Cd's, you'll get
750 to 1000 charge cycles over 2 to 4 years.
The disadvantage is a lower volts-per-cell and lower
apere-hour rating.  This should not be a problem since
the Grid battery pack originally Ni-Cd's.

With Ni-MH, you're get half the charge cycles and
double the price.  The advantage is Ni-MH cells have
higher volts-per-cell and better AH (Ampere-Hour)
ratings.  That means the cells can put out more
current over the same period of time as compared to
Ni-Cads.  In other words, they'll last longer per
charge cycle.  You'll need a Ni-MH charger as well.

I don't know how much money you're willing to put into
this project, but Li-Ion is the most expensive.  Those
are about double of the Ni-MH.  Li-Ion has an even
higher AH rating.  Again, you'll need a Li-Ion
charger.

I was poking around on the web.  Perhaps this place
may be able to help:
http://www.onlybatteries.com/index.asp

I've used this company to rebuilt several of my
cordless drill battery packs:

Good luck and let us know what you decide to do.

Subject: Re: GRiD chips

Just as a followup, The chips that can be used are any of the 27C
series of EPROMS. Just remember that even if you use a 27C256 or
27C512, you will only be able to use 128K of the memory because that
is the maximum amount of storage in RAM the computer will allocate
to it. The usual chip used for the application ROMs seem to be the
27C010 which is a 32 pin 128k CMOS EPROM. You want to use the "C"
series chips as these EPROM use less energy than the NMOS chips.

Now it would be nice if someone could write a program that would
allow the switching of the memory sections of the application ROM in
and out as needed, just as the process is done in extended RAM, then
you could use the entire contents of a 512k 27C512 chip for storing
programs. Can't use the 1 megs though as they usually are 40 pin
chips.

Well, originally, I wanted to do Li-Ion. The cost is something I am
not too concerned about. But the need for a separate charger deters
me from it. I think I will try the Nicad option first, since the
ones we have now are better than the ones twenty years ago. It would
also be easier to replace since I only have to unsolder the old
batteries and put in the new ones. I may look at the Li-Ion later
with the other battery pack I have,

Glad to have you on the forum, Paolo. I hope you enjoy the
information here. As to the "Sentry Gun" program you are refering to
from the movie "Aliens", I am not sure if that was a real program
that was designed, or if it was just a program name created for the
movie. If it is a real program, to be honest I had never heard of
it, although I have seen the movie. Perhaps some of the other
members here may have. While we are a general forum for all Grid
computers, the membership here mostly deals with the 1520 and 1530
models which came after the Gridcase III. The Gridcase III is an
8086 computer while the 1520 is an 80286 computer and the 1530 is an
80386 computer. Anyway, I hope that someone else on the forum has
more knowledge than I do on this.

I've seen the movie Aliens once or twice.  I don't
remember the scene(s) with the Grid.
Could somebody capture the scene in MPEG or MOV format
and send them to me?
My plan is to eventually write code to duplicate the
scene.
It can't be *that* difficult, right?  The processor in
the Gridcase is an 8086.
Everyone, please do not think I will get this done
tomorrow, next week or next month.  It will be a long
time until I complete it.

The grid (gridcompass 1139) is used as the remote sentry
gun terminal.

It is in the extended edition of Aliens, not in the theatre version.

Some people have written various programs, but none as identical as

the film version. Some people think it was written in the Grid OS.

chances are it was written by an engineer at GRiD or a colage student at DeVry. 
It was popular in that day & age for film makers to visit engineering departments and solicit help with the technology they where using.   I recall that the graphics used in the original Battle Star Galactica was written at the Chicago Devry campus.

That's great, Charles,

However, do you know the process by which the chips are programmed? I
thought there was some sort of program required to code the chips
just right. I had thought to program MSDOS 6.22 on one (If it would
fit. But I have a feeling it won't.), and some other stuff, but is it
as simple as simply loading the files onto the chip just as if you
were copying to a disk?

I don't have the process, however it probably wouldn't take much to hack the one I have that is programed.   Perhaps try to mount the image file, than maybe we only need Linux and 'mkfs' command to create an image file.

Hey all,
I just installed a new DTC on my 1530 motherboard.  I was getting the
classic symptoms of a dead clock chip.  Put it all back together and
for some reason, the system is not seeing the HD.  The drive is a
standard 20MB Conner, and appears to be spinning normally.

Must I reload a BIOS for it to recognize a C drive installed now?  And
if so any help there?  Also, I don't know if the drive is bad, might
there be a way to check if the drive is functional through the A drive
(I can boot up Win 98 on a floppy no problem)?

Thanks for the help in advance.  Sure do love this ole GRiD.  Has been
running though in years.

Hi, jorr_psu

Welcome to the forum!

I am assuming that when you installed the new DTC that it was either
an exact duplicate 1287 (not avaiable commercially) or the 12887
(which is what is used to replace it these days). If so, then
the "invaled configuration error 02" message should have disappeared
when you booted up. It that message did go away, then you did the
right thing and the computer is now enabled to recognized the hard
drive. Unfortunately, the Conners were notorious for going bad, and
even though your HDD seems to be spinning normally, it most likely is
bad, which is why the computer cannot see it even now when it should.

As to the BIOS, it is located on the two BIOS chips inside the
computer and is fixed. You can't change it without replacing those
chips. If you do, you have to be sure that what you put in its place
is properly programmed, for which someone experienced in assembly
language would have to do. There is no BIOS setup program of any kind
that you can get into at bootup for this computer.

In your case, you would have to replace the HDD. They are very
difficult to find. There are only six hard drive types (though in
reality only three Conner HDD, the 20MB, 40MB, and 100MB that they
recommended) that this computer will accept because it is programmed
that way in the BIOS. You can put another HDD of the same era that
fits the pin configurations (early MFM protocol, the predecessor of
the IDE), but you would have to reprogram the BIOS to accept it.
There are instructions in the files section on how to do this, and it
has been done both by myself and by Shawn.

Good Luck,

Phil

Subject: RAM Memory problem

To you guys with 1520's, you might be able to help me here, since I'm
not as familiar with it as I am the 1530. I recently obtained a very
nice 1520 in pristine condition with the original 20MB hard drive still
working and 1 MB RAM. It's runing MSDOS 5.0. However. I decided to
switch out the 256Kb RAMsticks for four 1 MB's I managed to obtain. I
ran into something I've never seen before. The computer Mobo will not
reconize the new RAM as 1MB, and will only see them as 256Kb sticks.
Now these new sticks are nine chip sticks so they do have the parity
bit included, which shouldn't make a difference, but I was wondering if
any of you ever experienced this problem. And I know the chips are 1 MB
sticks, and that they do work. It's not a software problem, because the
system on bootup, even before the BIOS is read completely, will not see
more than 256 KB on each stick. So I was womdering, am I missing a
jumper somewhere? Does parity make a difference on these RAM sticks?
I've searched the manuals and nothing there seems to tell me anything.
Have any of you guys run into this problem? Thanks.

Hey Phil,
I'm not 100% sure but I think it may have to do with
which "bank" the sticks are loaded in to.

I'm not near my Grids now so I have to do this from
memory.
There are 8 rows, right?
If I had to guess, row's 1-4 have 256k and 5-8 have
the 1 Meg.  Or, you may have rows 1-4 with 1 meg and
rows 5-8 with 256k.
Whatever your configuration is, try putting 256 in
rows 1 and 2, then 1 meg in rows 3 and 4.  Then, put
256 in rows 5 and 6, and 1 meg in rows 7 and 8.
See what it reports.
Good luck and let us know the outcome.
Thanks,
-Shawn

Subject: Re: RAM Memory problem

Actually, Shawn,

You can't mix 256Kb with 1 MB. They have to be all of none or all the
other. Otherwise you will get a memory error and the unit will freeze.
The thing is that you are allowed to use only the following memory
configurations:

1 MB:     4 256Kb sticks
2 MB:     8 256Kb sticks
4 MB:     4 1 MB sticks
8 MB:     8 1 MB sticks (technically, this is not supposed to be
allowed on the 1520's according to the manual, but I know it's been
done and it works)

These are the only configurations allowed. Any other attempt will
result in an 'invalidation code 04' and the machine will freeze.

When you use only four sticks, you must use Banks 0,1,4, and 5
starting from the front of the machine. If you try any other
combination of bank loading, then you will get another memory error
for either the low or high memory byte being invalid, and the machine
will freeze again. I think I've seen some 1530's use alternate bank
loading (0,2,4,6), but that may just be for the 1530's

I've tried installing just four 1 MB sticks, but the machine will
only give me 1 MB memory total, treating them like 256 Kb sticks

I've tried installing eight 1 MB sticks, in which case the computer
sees them as a total of 2 MB memory, again as if they were all 256 KB
sticks. The extended memory mode appears to work fine in that
situation, which is why I don't think the memory mode has anything to
do with it. On the 1530, there is a jumper on some models you have to
use when switching between using four or eight sticks, but there
doesn't appear to be one on the 1520.

So at this point, I am at a loss as to why the computer cannot
recognize the memory modules as 1 MB modules, seeing them only as
256Kb. These are nine chip sticks, which means they have parity
checking (Even number chip sticks lack parity checking. Odd number
chip sticks have parity checking), but this has never been an issue
before in the early a computer as they always use non-parity memory,
so the adding of parity wouldn't change anything since it isn't
utilized. But I don't know for sure. I am going to see if I can find
some eight chip 1 MB sticks and see if that does the trick. It would
be an interesting idiosyncracy if it turns out to be true.

It just may be the manufacturing and the design of the chips as well,
unfortunately, but I've gotten this now with three different sets of
chips, so I doubt it.

Anyway, I'm still trying to figure it out. *sigh*

Thank you Phil!

I did in fact replace it with the NEW 12887 DTC chip.  No more
configuration 02 error as you spoke of.

I did manage to run "gridscan.exe" from my old GRiDDos 3.3 disks.  It
hung up for some time on the C drive and when it popped up, it

What a shame.  I looked for a Conner drive months ago suspecting it,
and found one in the UK for like $500USD.  For a 20MB HDD, its insane
but because they are old and rare, it makes a lot of sense.

I've read the procedures for fixing the system with a new HDD, and
have the equipment available to me (with a couple techs to help).
Might not be worth the effort though.

If you know of anyplace that sells the drive, refurbed even at a
reasonable price, let me know.  Otherwise this other than HDD
pristine 1530 may have seen its last EXE...

Again thanks for the info!

Thank You, Jorr-psu

The question on the hard drives is indeed about how much you want to
pay for one. I have been lucky enough to find several in bargain
basement bins in discount computer parts stores that cater to selling
the old stuff at cheap prices. Of course, you take the risk that they
are dead anyway, and I did get burned several times. But at $5 or so
a pop, it's worth it. You would be surprised what you could find
sometimes. However, for the old Conner Drives, they truly are
becoming rare as chicken's teeth.

We here at RUGrid have been successful at adapting a few different 
ones of the Conner drives. Shawn has adapted a CFS420A to a 1520 and
I adapted the same hard drive in my 1530. I have also adapted two or
three CP30174E's, a CP30104E, and a couple of others I can't think of
right off hand (all Conners)

The list of Conner drives that might be able to be adapted are as
follows:

CP30104E
CP30174E
CP30084E
CP30080E

CP30084
CP30100
CP30084

CFS420A

The following are the original HDD's that Grid used:

CP3020
CP3040
CP3044
CP30100

and possibly these too:

CP340
CP344

To date, no one in our group has tried adapting a different brand HDD
to the Grid computer that I know (I have seen old HDD's with the same
MFM pin setup by different manufacturers out there. But whether they
could be adapted is an unknown. We've stayed safe here by sticking to
the Conner brand.)

Here are a couple of sources for these hard drives that might be
helpful. I think the prices may still be hefty, but it would probably
be better than what you are getting there in the UK.

http://www.codemicro.com/support/disc/specs/family_conner.html

http://www.powersourceonline.com/iris-item-search.oem-Conner-s-en.jsa

I hope you'll be able to get what you need from there. But I really
don't know what they will charge you. I also don't know that the 
prices you see on the first URL are true anymore. You would have to
call and find out. The second URL lists all of the Conner HDD's that
were made, I believe. But not all of them can be used in a Grid. You
would be best served by staying pretty much within the same family of
HDD as the list above and under 500MB. The CFA family may also be
usable in a Grid, I believe. Your only other option is to get a
specialty company to refurbish your original Conner 20 MB HDD, and
that's expensive, too. But anyway, good luck.

I know you want to get this 1530 up and running, and I do wish you
luck. But if for any reason you don't feel it's worth it, or you
can't get it going, I'm willing to take it off your hands. The 1530
is the Grid with which I especially like to deal, and I am set up to
refurbish them somewhat.

 The placement of the chips is very important as
Charles alerted me to a long time ago. I seem to
remember that 4 chips went in the 0,2,4,6 slots, but
my memory must be wrong. For some reason I'd thought I
had gotten the memory up to 4megs, but it must have
been 2 using 4 other 256k chips. In any case Win 3.1
worked fine on it. Perhaps not in protected mode.
I remember being amazed and delighted when I found 
the 1520 could use EXTended as well as EXPanded
memory.
Possibly that's a feature of the OS (MSDOS 5 or 6.x)
not hardware.

With 8 1M it shouldn't be a problem unless it's
related to the chip parity structure or speed, or the
jumper referred to in the below usenet message.
There's even references in my Grid archives of
increasing 1530 memory to 16meg using kits from
now-defunct dealers ? (2meg chips ?) I have another
message referring to it.

 There are also references to defunct dealers offering
an 8 1meg chip upgrade in the old Laptop group on
usenet. Don't know if Google still maintains it but
FUNET might.

 Here is an old usenet message from my archives of the
files I was trying to upload here which went so wrong.

It refers to the 1530 but could also apply to the
1520.

 While I can't speak for the 1550 specifically (I have
the 1530), my understanding was that the 1550 was
really a 1530 with an expansion slot. If this is
correct, I would certainly try putting all of the
memory in one system. 

If I understand correctly, each of your systems
currently contains four 1 MB SIP's, and each system
could accommodate eight 1 MB SIP's.
Assuming that the SIP's are all relatively close in
speed (most likely they are all 80ns), putting all 8
of them in one system should work just fine. 

With only 4 SIP's in a 1530, a small jumper is used to
connect 2 pins that are located  between the keyboard
and the memory. If you install all 8 SIP's in one
system, you will want to remove the jumper
(it pulls off easily).

I believe that your memory access speed will also
improve with all SIP slots populated, due to the
memory being organized as 2 banks (4 SIP's each), with
interleaved access. While I am no memory expert,
it is my understanding that an additional wait state
is incurred when only 1 bank of memory is populated.

Disclaimer: Just my opinions, based on extensive
tinkering with a 1530. In short, good luck.

Subject: Re: RAM Memory problem

Thanks, Lawrence,

Good to see you back.

I have seen the 0,2,4,6 placement in some machines, but in this 1520
that I have, it gives me the memory low byte invalid error, so the
only configuiration that will work in this machine for four sticks
is 0,1,4,5. I think the 0,2,4,6 configuration was unique to the 1530
actually.

The difference between extended and expanded is that extended simply
allows a direct adressing protocol for memory above the 1 MB KB
limit. The 384 KB after the first 640 KB is left alone as MSDOS
mandates that for use with expanded. This of course gives you only a
maximum of 15 MB of addressable memory above the base 1 MB. Expanded
memory uses that 384 KB section above the base 640 KB to be able to
address all RAM memory above 1 MB and then gives you a maximum
addressable memory of 4 Gb.

Expanded memory is addressed from within the lower 1MB space,
usually above 640K. It is sometimes up to 64K of real addresses but
this is just a small portion of the whole expanded memory, which can
be very large. The expanded memory requires hardware and/or software
that maps the expanded memory to a piece of address space, in what
is called a "page frame". Extended memory can be used as expanded
memory by using software and the 80286 or 80386 chips to "remap" it
to the lower 1MB. It should be noted that the 80386 chip has
hardware built in that supports expanded memory while the 80286 chip
does not. Software that will convert extended memory on an 80286
machine to expanded memory may result in a significant performance
penalty, if the machine does not have special hardware support for
expanded memory. Software that will convert extended memory to
expanded memory on an 80286 machine is not written to use the
special hardware built into the 80386 chip, so the same type of
performance penalty may apply.

The problem here is still in in the bootup. During the POST the
computer does the initial testing of the RAM and still only sees the
1 MB sticks as 256 KB sticks. This is done before any of the
config.sys commands commands come into play designating the memory
mode as EXT or EMS, which is why I don;t think it is part of the
problem. I don't want to switch the memory mode just yet. For
similar reasons, I would doubt the version of MSDOS being a factor.

However, lacking any other knowledge, I may try switching the
compputer from EXT to EXP and see if that works, or upgrading to
MSDOS 6.22. I may need an EMS manager to make that work.

But somehow I still think this is a hardware problem on the Mobo.

Ok Phil,

I will check on the sites you mentioned.  And will let you know how we
fair out.

Alas if I cannot repair her, I think I might as well let her go,
especially to someone that might know how to get her running better
than I.

I have a GRIDCase 1530, VGA if I remember.  The onboard display is B/W
not the amber/orange one.  I always used a VGA monitor with it.  I
have several GRiD battery packs I grabbed up a few months ago.  I also
have the GRiD network adapter that inserts nicely into the battery
slot.  I have an Ethernet switcher to match it (not sure what it does
though).  I have an external GRiD 5.25" drive (man, that brings back
memories) and cable, and a GRiD numeric keypad that connects to the
system via the connector in back (old PS2 type).  The GRiD used to be
a desktop for me and the numeric pad was essential.  The power supply
is fantastic (not to mention shiny chrome) for these things.  I used
mine a lot long ago onboard miltary aircraft, running fine using
aircraft 400Hz power.  Right at the upper limit, but the power supply
was fine (if not a bit warm!).  I was the envy of the crew.

System works great booting from the floppy.  Haven't dragged the old
monitor out of the closet yet to check the VGA out.  You know I might
just do that this afternoon (hehe).

I also have all the original documentation, as well as the original
black GRiD DOS case with manuals, a GRiD ROM building guidebook,
working 3.5" and 5.25" MD-DOS discs, various quick help cards, all
nicely tabbed.  Thanks to all you folks, I have several discs of
utilities and other files acquired mostly from this site, but a few
other places.

The system is basically pristine, as I cared well for it through the
years.  In fact the HDD never failed me while I used it.  It seems to
have failed as it sat in the equipment closet, all wrapped up nicely.
 Go figure.  I suppose that is why I want to fix it now...you just
can't buy GRiD quality anymore.

Anyway thank you for the great info.  And if I fail I'll let you know
when she's available.

Dear lam_jim,

Glad to have you on board with RUGrid. The POST beep codes can be found
in the Hardware Service Course Student Guide starting on page 52, which
you can download from the files section here on this forum. The beep
code you have given shows that that there is a "64K RAM chip or data 
line failure - Bit 8". This suggest that one of your memory sticks has
gone bad or the connection of one of the pins is bad, possibly from
getting wet and cold. You should try taking out your memory sticks,
cleaning them if needed, and reseating them again into the motherboard.
If that doesn't work, find a tester for your memory sticks and see if
one of them has gone bad, in which case you will have to get another
one (or a new set, depending). Hopefully, it is not due to a break in a
line on the MoBo itself, but I believe that to be very unlikely.

Good luck,

Jeriddian

Hi, lam_jim

Trying to repair a broken pin on a SIPP is damn near impossible without
tearing it up. First, you would have to get a replacement pin from
another SIPP, which would tear it up. You are better off buying a new
stick or set of sticks. It really doesn't matter what brand or make the
sticks are. Any stick of SIPP from that era is going to be about 80ns
to 120ns in terms of speed, and the GRID can work with any of those
speeds. The 256K SIPP's are a little easier to find. I would suggest
going to ebay or looking at some of the computer parts houses that are
around that offer these old computer parts. You'll probably be able to
get away with paying a few bucks per stick (or up to $5 - 10). Although
you should be able to get any stick and use it, it is preferable to get
a matched set of sticks if you can possibly do it. Mismatched sticks
can sometimes result in memory problems, though usually they seem to do
okay if not.

You can use four sticks, or eight sticks of 256K SIPP for 1 MB or 2MB
of memory. If you use only four be sure and place them in exactly the
same slots required for four sticks (Banks 0,1,4, and 5, counting from
the front of the computer.). You also can use the 1 MB SIPP sticks for
a total of 4 MB RAM again in banks 0,1,4, and 5. Although GRID never
recommended using eight sticks of 1 MB SIPP' s in a 1520, I know it has
been done and will work.


Good luck!

Jim:

You have to look  at the pads on the sip.  In the past I hove used pins from an DIP socket to replace broken pins.  This is best done with 0.016 diameter solder and a fine tip under a microscope.  I also used a socket to hold the pins in alignment while I worked on them.   (note that I regularly solder under a microscope and am quite good at it.)

If you are not prepared to do the "micro-surgery" I recommend finding a vintage memory dealer, or a group member who has some spares.

 While I can't speak for the 1550 specifically (I have the 1530),
my understanding was that the 1550 was really a 1530 with an
expansion slot. If this is correct, I would certainly try
putting  all of the memory in one system.

If I understand correctly, each of your systems currently contains
four 1 MB SIP's, and each system could accommodate eight 1 MB SIP's.
Assuming that the SIP's are all relatively close in speed (most
likely they are all 80ns), putting all 8 of them in one system
should work just fine.

With only 4 SIP's in a 1530, a small jumper is used to connect
2 pins that are located  between the keyboard and the memory. If you
install all 8 SIP's in one system, you will want to remove the jumper
(it pulls off easily).

I believe that your memory access speed will also improve with all
SIP slots populated, due to the memory being organized as 2 banks
(4 SIP's each), with interleaved access. While I am no memory expert,
it is my understanding that an additional wait state is incurred when
only 1 bank of memory is populated.

Disclaimer: Just my opinions, based on extensive tinkering with a
1530.
            In short, good luck.
Steve

----------------------------------------------------------------------
 In an earlier post Jeriddian mentioned that only one size of SIPPs
could be used together. I wonder if that could be a memory bank
limitation, of which there are 2 according to this post, just as in
most later computers one can use different sizes in each bank. Also
the poster's comments about the jumper on the 1530. Many things are
identical I beleve on the 1520 and 1530. I'll find out when I open my
beast. Possibly a sharp rap with the rubber handle of my screwdriver
might even revive (temporarily) the Conner HD as it has done so
before.

If the use of different sizes is a definite no-no, I'll install them
in my spare 1520 unless there are working 256m sipps in it. Can't
remember, tho I know at one point I had all the slots in my primary
1520 populated after acquiring 4 256m Sipps off eBay. I know I do
have 4 256m sticks each with at least 1 "leg" missing. I will
certainly be cautious when inserting any of the 1meg SIPPs.

Lawrence

 Still can't understand why a BIOS "addendum" couldn't be written by
an experienced BIOS programmer to be used like the "overlays" which
overcome size limitations by most HD manufacturer, or for that matter
the BIOS insert pointers used by the GRID SCSI adapter. A "first-
call" add-on simply using the EPROM slots at the top of the keyboard.

 Hi Phil. I finally contacted the guy in Montreal
about the 1Meg SIPPs. As you will see in my Yahoo post
he still had them and graciously mailed them free and
even absorbed the cost of Shipping, only around $3 but
that doesn't account even for the effort of packaging,
etc. Nice to see people like this still exist, and a
touchstone for my own future behavior. Especially with
some of the junior nerds who I sometimes dismiss out
of hand for their freeby expectations and bad manners.

 I didn't mention in the post that you had supplied me
with the lead lest it lead to petty jealousies or
bickering, but my thanks for you pointing me to him.

 I realise you aren't a big collector, but should you
have any need for older free parts, programs, or

 Aarrrghh. I received the mem. sticks today, but they aren't SIPPs
they're SIMMs. I screwed up in not verifying that they were indeed
SIPPs, but perhaps he didn't know the difference. The gods must be

Subject: Re: Accessing Gridcase 2 ROM's

I can answer this question, I think, but it is so old I wonder if
anyone here would care or if it has already been answered in another
thread.

The GRiDCase 2 should boot from that DOS 2.11 ROM if it is working
correctly by default.  To make it boot from the floppy when there is a
boot rom installed you have to hit the "F" key just after the POST beep.

The ROM's should look as files that are concantenated to the file list
of the diskette in the floppy drive.

That is the way it is supposed to work.  If yours only boots from the
floppy disk (without hitting the F key) then your DOS 2.11 ROM's are
bad or the system is not reading the ROM sockets correctly.

Hi Dave,

There are two major revision in regards to this question. The earlier
versions of the 153x had the 184810 time chip which did require the 
outside lithium battery to maintain the CMOS circuitry. The later
revision got rid of the the battery and the 184810 time chip and
substituted teh Dallas real time chip which incorporated the CMOS
circuits and the battery all in one package. The battery was slated to
last about 7 - 10 years. The Dallas RTC was originally a 1287 chip, but
they don't make that anymore. You have to use its direct replacement
which is the 12887. You will see 153x mobo's that will have the place
for the battery, but there's no battery. Those are the ones that have
the Dallas RTC in them.

You're welcome, Dave

Actually, I think you have the better deal. The only thing you have
to do with the separate lithium  battery version that you have is
replace the battery every ten years or so, which is easy to do. The
problem with the Dallas RTC versions is that you have to replace that
whole IC chip on the motherboard, and if you don't have experience
soldering and desoldering circuit boards and replacing IC chips like
that, you can really mess up your computer in a hurry. The other
option is to modify the old Dallas 1287 RTC in a way where you can
attach a new battery onto the chip (This is described in our files
section), but that still involves desoldering and removing the old
Dallas RTC chip in order to just work on it. I have successfully done
that on three of my computers. So count yourself lucky that all you
have to do is replace the lithium battery.

Dave,

I'm talking about the computer itself, not the expansion tray. I
obtained a 1535 and the upper back cover was missing. The backplane
for the disk drives was installed, but there was nothing in the drive
bays, just the support plate for them. The bottom bay where a hard
drive would usually go is taken up by the PC board that connects the
mobo to the bus connector that connects to the expansion tray through
the bottom of the computer. But the top bay is fitted for the floppy
drive, exactly where the floppy drive usually goes in other 153x
series computers. The back plane also is fitted for a floppy drive
there in that upper drive space, so it seemed logical that a floppy
drive would go there. But I admit I've never seen a 1535 with a
floppy drive there, although it makes sense as the connections for it
are there.

Hi guys ..

Web hosting is cheap.  Download everything you can, and put up a web 
site.  For $60 to $100 per year you can have all of the space and 
bandwidth that a Grid support group will ever require.  For that money 
you can also probably put up a dedicated web forum and ditch these nasty 
Yahoo ads.  :-)  And for another $12 per year, you can have the domain 
name or your choice and never change homes again ..

Uh..... ......guys

I am part owner of a web hosting company (plus graphic design,
animation production and design, television production, web site
design, and Web site advertising). I'm sure that if you want to set
up a web site, we could do that. I already own a license to vBulletin
software that I don't mind it being used for this. (I am using the
same software for amother site which I admin.) I am sure that we
could come to an arrangement with anybody that would want to admin
such a site (I really don't have the time for it, myself.), which
would be even less expensive, plus you'll have an in with one of the
owners of the web server and hosting company. Of course, Shawn has a
server, if he would like to try it, but we're a little better
situated with ours as we host multiple accounts, and I have the web
site software to start it. It's up to you guys if you would like to
do it.

I don't mind "hosting" anything.  Just let me know -
but you have to accept the limitations.

The "server" isn't really a true server.  It's a 663
MHz Celeron PC running Ubuntu Linux.  It's in my house
that's serviced by Verizon DSL with 865 kb/s down, 160
kb/s up.  Verizon blocks port 80 so http service is
out.
Because port 80 is blocked, it probaby wouldn't be a
good idea for me to host it.

Subject: Backlight on 1535

I've searched the messages here and can't find the answer to this.
I've got a 1535 with the LCD screen.  It has a generic DOS loaded on
it so I'm probably missing some GRiD-specific utilities that I need.
When I power it up the backlight comes on for a second and then goes
out.  Everything seems to work fine, but I can't figure out what I
need to do in order to make the backlight come on.

Can someone shed some "light" on this for me?

Thanks!

Dave,

You can search the files for the GRID specific GRiDDOS 3.3 boot up
files or boot disk. Also, if I remember correctly, there is a command
that goes BACKLIGHT=ON that should turn the backlight on. The tech
manuals may likely elucidate further as well.

I believe I had to use a version of mode that was called mode2.exe on
one of the disks (which i took and renamed back to mode.exe.  If I
recall correctly, the command might have been a mode backlite=on, if
not backlite, then backlight.  The change should be relatively
"permanent", you can shut the machine down and boot up linux and still
have light.

Backlite commands:

First you will need the executables from he vault.
http://tech.groups.yahoo.com/group/RuGRiD-Laptop/files/Grid1520files/
In that zip is a file called CONF1520.EXE (If I remember correctly)
The command will be a command line call to that program

CONF1520 Backlite=0n

I may be wrong, but I don't think conf1520.exe will
work on a 1535.

Hey Phil,

Looks like you got a decent deal on that 1535 on e-bay.
Congratulations!  Is that a plasma screen?  Looks larger than the
plasma screen on a 1530 but I've never seen that version of the 1535.

Thanks, Dave,

    Yeah, I think I did good. It appears to be fully functional, and I
have an expansion tray I obtained earlier to mate with it, so I'll see
what sorts of old hardware ISA cards I can find to try with it. It
looks like an amber plasma screen all right, but it's the same size as
the 1530. I guess they usually had LCD's for the 1535's, but I see no
reason they couldn't use a plasma as well, since the motherboard and
internal workings for a 1535 are actually the same as a 1530. The only
difference is that there is no HDD because that bay is where the PC
board is located that connects the bus of the motherboard to the
external connector that is on the bottom of the computer and fits onto
the expansion tray. Anyway, I can conceivable connect all sorts of old
ISA hardware cards, including HDD's and whatever. The expansion tray
gives me two slots to use.

It'll be fun to use. :D

I may be missing something, but it looks like it booted from the "C"
drive in the photo.  I think you have a HDD in it and it works!  In my
1535 the hard drive is in the "normal" place, just a bit higher in the
chassis.  No room for a floppy drive and a HDD because of the
expansion board, I think, but a HDD alone, yes there's room.  Maybe
I'm not understanding you about that.

I have a 1530 with the plasma screen and the aspect ratio is different
than the photo of your new one.  It is shorter, like the older
8086-based GRiDcases on mine.  Yours looks to be the same aspect as
the LCD version that I have.

Looks like fun!

Hmmm,

You may be right then, Dave,

The bottom bay is taken but the top is bay is available. I just
assumed that there would be a floppy drive put there as the back
plane for the other 1535 I have has the connection for a floppy, not
a HDD, but if you had the right backplane for it, you certainly could
put in a HDD instead of a floppy. You just wouldn't have an internal
floppy drive then. But as to booting up, it doesn't need a HDD if you
have a plug-in 32 pin accesory IC in one of the accessory slots
that's programmed with the boot up files.

I am familiar with the EPROM sockets in GRiDcase computers.  I've not
used them in the 1535, but in the 8086-based ones, the EPROMs look as
extensions to floppy drive.  That is, files and logged in drive letter
is A, not C.  That's why I think the one you bought has booted from a
hard drive.  But I'm not sure that the 1535 is the same as the
original GRiDcases in that respect...just a guess on my part.

If I'm right, then you have in that machine one of the rare Conner
drives that works!!!

Good luck with it!

  I just ran across this and I'm not sure whether someone else may have
posted a similar fix for the Dallas RTC, in order to use regular
batteries on the Grid15xx. If not here's Peter Wendt of the MCA Mafia's
solution. A bit involved, but likely no more than desoldering and
replacing the 1287A if you can even find one.

Thanks, Lawrence,

Atually this has been addressed in the past and there was a link to a
German web site which detailed this same fix, although definitely in
more detail. I have performed this fix myself three times. I find it
easier to actually desolder the RTC 1287 off from the motherboard in
order to do this work as it is to easy to damage the motherboard
itself otherwsie. But it does work very well. If you have a 1520 with
the RTC 1287, you are pretty much obligated to do this. You cannot
replace the 1287 with the newer 12887A because then the time circuits
will never reset and you will never be able to boot the computer up,
so you have to perform this fix in order to restore it. On a 1530,
however, the circuitry is a little more advanced and you can replace
the 1287 with a newer 12887A and it will boot up properly afterwards.

Hi, Nick.

Glad you could join us. In response to your question, yes. Leaving
the old battery in the circuit will drain the power out of the new
battery like a short circuit and probably bring the voltage down
where it couldn't work properly. The modification requires that you
severe one of the pin high up on the package on at least one terminal
of the old battery as a result in order to prevent that from
happening. It's a little tricky, but if you are careful, it's not
that hard. I've done it s few times already with my units.

Thanks, I bought this grid 1520 a couple of months ago and have been

because I spent most of the other night drilling the holes manually

Thanks, I've gotten the holes drilled and the ground of the battery
disconnected, after that I just have to solder the battery pack leads
on. Would you guys have any suggestions as to finding hinges for the
display? Even after being about as careful as I could and after having
read many of the posts on disassembling the grid 1520 I still managed
to break the right hinge. Thanks.

You'll have to scavenge them off a broken unit that's sold for parts,
I'm afraid. The earlier hinges were made of metal, but later ones
were made of plastic.

Amazingly enough, after drilling the holes (I never got around to
soldering the leads on to the chip, decided to get a new ds1287a as a
backup first) I hooked everything back up together and booted it up.
The harddrive came back to life, it was dead before hand. I'm going to
guess that it has something to do with disconnecting the ground lead
for the battery in the ds1287a.

Nick,
For whatever reason, it appears that if the Dallas RTC
or CMOS battery (in older units) is dead, the BIOS
doesn't "see" the hard drive.
It appears that some sort of "default configuration"
is loaded and this configuration doesn't include the
har drive.
Why?  I don't know.

From: Shawnerz
Subject: New 1520 User

This was from a new user named Vicki:

"I aquired grid gridcase and gridcase 1520. I know NOTHING about
they power up with red lights, but screen isnt coming on. i
dont have original adapters,I NEED HELP!!! Vicki "

Hi Vicki and welcome to the group.  

The Gridcase is an 8088 or 8086 processor from the mid to late 80's.

The 1520 is an 80286 (or just 286) processor from the early 90's.

Red lights, eh?  You mentioned not having the original adapters.  I don't know exactly what you mean by that.  If you mean "power adapter" this could be causing the red lights.  The power supply must be capable of 16 volts at about 2.5 amps (turn on surge.  It should settle down to about 1 to 1.5 amps steady state).  If you're using a 12 volt power supply, you will get the red lights.

If you have a 16 volt power supply and are still getting red lights, then it is possible internal componets are bad.  The hard drive (if installed) could have seized and is drawing too much current.  It is also possible the display (or its power supply) has gone bad.

Well, those are a couple of things to look at to get you started.
Enjoy,
-Shawn

ok, I DONT have the 16v, I used my Nintendo NES
adapter.  WOw did it get hot fast....

I have a 1520 with battery.  When I put the nes
adapter on it, the floppy drive on side flashes red,
then 3 of the 4 lights on front flash, no screen comes
on.

I also have a grid gridcase, no visable model number
like the 1520 has.  That DOESNT have the battery. 
When I hooked the nes to that, the ONE red light on
the front came on and that is it.

WHere can I find a CHEAP 16v to test these 2
properly??

I want to sell them...

Yeah, the NES adapter couldn't supply enough current.  That's why it got hot.
As far as locating a 16v power supply, I think the easiest way to have someone loan you one.  I think I have the one for the Gridcase, that I can loan you, but I don't think it will power the 1520.  I have several 1520's, but I power them with an external, variable power supply.

Subject: Re: New 1520 User

Dear Vicki,

There are some power supplies on ebay at the following URL:

http://cgi.ebay.com/Grid-AC-Adapter-Notebook-computer-Output-17-25V-2-
0A_W0QQitemZ190035646652QQihZ009QQcategoryZ101265QQrdZ1QQssPageNameZWD
1VQQcmdZViewItemQQ_trksidZp1638Q2em118Q2el1247

However, they are listed at 2.0 amps, not 2.5 amps, and they are
apparently meant for another type of grid computer other than the
1520. But they may work.

If you look at this URL:

http://cgi.ebay.com/ws/eBayISAPI.dll?
ViewItem&rd=1&item=260228599736&ssPageName=STRK:MEWA:PIC&ih=016

It is a 1520 recently bought on ebay, but if you click on the
pictures below you can see the rear of teh computer and see the power
supply inserted into the back of the computer. That's what the power
supply normally looks like for this computer. However, this power
supply is rated at 17.25 volts at 3.25 amps, althoguh I think the 2.5
amp supply should work also.

use outputs 19 volts at 2.40 amps, starts the unit and charges the
dead battery to last 15 minutes.

From: me
Subject: Re: [RuGRiD-Laptop] Re: New 1520 User

Hello all, a quick update.  I found a guy on ebay who
had GRID power adapters.  It arrived today and powered
up the 1520 perfectly!!!  Screen came on and is
looking great.  I dont know what to do with it from
here....but I have listed it on ebay under my user
name camnma5pt0.  

The other case, model unknown, would not power up or
even a red light with this new adapter...weird.  It
did power up slightly before with my nintendo ac
adapter with a red light that came on...but nothing
with the new adapter...weird.  

So that unknown model is just sitting here....anyone
care to make an offer????

Thanks for all the help out there guys!  If you have
any ideas on what I can try typing into the 1520 to
see what programs I can access, let me know!

Vicki

Hallo!
I found an ethernet pod for my Grid 1520 and now I would like to try
to connect the Grid in a network LAN.
I have already installed on my Grid the MSdos 6.22, I got the driver
for the ethernet pod from the ARI web site and connected to the
ethernet port I have an AUI transceiver with a Rj45 socket.
I found some information on google about the possibility to connect a
PC running msdos in a network but I'm still confused.
I would like to install on the Grid a telnet application and email client.
Any help will be appreciated, thank you

Andrea,
I have 2 Ethernet pods as well.  One day when I have time, I would like to get mine working as well.
I have Windows 3.11 disks.  I think there is limited networking support in Win 3.11 but I do not know if the Grid pods are supported.
Good luck and let us know if you are successful.
Thanks,

Ben,
Welcome to the group.
Short answer: yes.  
Depending on when it was made, it may have a Dallas Real Time Clock (RTC) chip instead of the CMOS battery.
You won't know until you remove the semi-flexible cover in order to get to the motherboard.  This is the cover that surrounds the keyboard and slopes under the display.
Good luck,
-Shawn

From: Shawnerz
Subject: Re: [RuGRiD-Laptop] Re: Grid 1520

Ben,
You've got to ask the tough questions, don't you? ;-)
I am doing this from memory without being actually in front of my 1520.  So, I might forget a setp or two.
You'll need a Phillps (a.k.a. "cross tip") screw driver, needle nose pliers, dykes (a.k.a. "side cutting pliers"), and a soldering iron. 
At the rear of the unit, there are two rubber feet.  Remove the feet and you will see a screw.  Remove the screws.
You will then be able to remove the top cover that covers the rear half.
Move the display out of the way.
Gently, yet forcefully, remove the plastic cover that surrounds the keyboard and slides under the display.  There are no screws that hold this down but the plastic catch holds it in place very tightly.
You should see the pink battery on the right side very close to the RAM SIPPs.
If you've gotten this far, you have to decide if you want to do it the "quick and dirty" way, or the proper way.
The "quick and dirty way":
Cut the leads coming from the battery as close as you can to the battery.  In other words, you want the battery leads to extend from the mother board as long as possible.
Throw away the battery.
OBSEVING PROPER POLARITY, put the new battery in place and intertwine the leads once or twice.
Solder the leads so the battery is held securely.
Replace the display and covers, and you're done.
The proper way:
You have to remove the motherboard from the chassis.  In order to do that, you have to:
    Remove the screws that hold the keyboard.
    Disconnect and remove the display.
    Unfasten the mylar strips that go over the hard and floppy drive assembly.
    Remove the screws that hold in the internal DC-DC converter (power supply) next to the hard drive assembly.
    Remove the power supply.
    Remove the screws that hold in the hard/floopy drive assembly.
    Remove the hard drive assembly.   
    If my memory is correct, at this point, only the motherboard remains in the chassis.
    Remove any screw that is holding the motherboard to the chassis.  TIP: Keep the spacers with the screws!
    You should now be able to remove the motherboard (if your 1520 is anthing like my 3, you will find all kinds of dust, dirt, and             debris between the motherboard, the plastic insulator sheet and the bottom of the chassis).
    Locate the battery and unsolder it from the motherboard.
    Install the new battery, solder it in and trim the leads.
    Put it all back together by repeating the above steps in reverse order.
That's it!  Let us know how it goes.
-Shawn

Once I make it into a pdf, I will make it availible via ftp from my server.
In the mean time, the drivers are available in the Files section ("15XX Lan Drivers.zip").

Hi

I found a 1520 in a pile of old computers and would like to get it
going if possible.

Well here goes,
pluged it in got beep code 1-3-3 so i played around with the sipps
till i got past that(broke one and ended up with one in socket 1 and
5).

now i get beep code 1-2-1 but its kinda slowed down compared to the
other beep code. this is followed by a single beep then the floppy
lite flashes then the hard drive lite comes on and stays on.

Things i have done so far:

(the screen does light but shuts off after the error code)

removed screen
removed video board
removed keyboard
removed floppy and hard drive connectors

results:

beep code 1-2-1, 1 beep ,floppy lite flash , harddrive lite flash
then sometimes 2 beeps.

So the conclusion is the mb has a problem and my question is were to
start.

If anyone could point me in the right direction that would be great

Hopfully not back to the garbage

Thanks

Hi, Klyball,

If I read your statement right, then you have only two sticks of
memory in banks 1 and 5. If that is the case, then I understand your
beep codes, which are telling you don't have all the memory in place.
The computer will not work at all unless you have the exact memory
configuration which must be as follows:

A: Four sticks of 256K memory in banks 1,2,5,and 6 --- or
B: Eight sticks of 256K memory in all eight banks ---- or
C: Four sticks of 1 MB memory in banks 1,2,5, and 6 --- or
D: eight sticks os 1 MB memory in all eight banks.

No other configuration will work except these. So you need to find
some more 256K 30 PIN SIPP's (you can occasionally find them on sale
aon ebay), and put either four or eight of them into the memory banks
as I have outlined above. The computer simply will not boot up
otherwise.

Hope that answers your question.

Phil

All,
I was planning to respond by looking up the error code in the service manual.  But someone hacked in to my Linux box using ssh, "su"-ed to root (which I'm not sure how they did that since root is an inactive user), and deleted everything on the drive.  The drive housed only /home to all of my users.  Unfortunately, griduser was one of the users.  The service manuals stored under griduser are now gone.  I was lucky that I copied them off of the drive as a backup.  So, I still have them.  It is just problematic.
I just thought I'd share my pain.

Hi
thanks for the reply

I have worked out the ram and have 4 sticks in 1,2,5,6,

system still is responding with 1-2-1 , I'm suspecting a video card 
problem but don't know if having dead video card or card removed
would give the 1-2-1 code, can some one confirm a 1-2-1 code with
card removed. When power is applied the screen comes on with
horizontal and vertical line that fade away.

the sytem responeds to ctrl-alt-del after it trys the floppy

Question is what happens when booted without video card out?

Does it give error code with battery removed?



Thanks for your time

p.s. I have dumped the bios chips and the pld p5c090 there are two
other pld's p5c032 that i could unsolder and read if needed,

The 1-2-1 error is programmable interval timer error

Also what is the grid chip to the left of the battery the battery?

Subject: Re: Trying to bring a 1520 to life

Hi, Klyball,

The 1-2-1 beep error is indeed the programmable interval timer
failure code and this may refer to the Faraday 3010 chip (I think it
is labeled as such) on the board which combines three units, which
are the two 8237 DMA controllers, the two 8259 Programmable Interrupt
Controllers connected in cascade mode, and the 8254 Programmable
Interval Timer and Timer Channel control, and the refresh address
counter. If the beep is sounding this, I wouldn't know exactly where
the problem is. It could be the chip itself is bad, or there is a bad
conection somewhere along the way in its wiring. Without a strong
knowledge of the actual physical electronics and a good work bench
with the proper tools (Scope, generator, meters, etc.), I couldn't
begin to tell you where to start. My knowledge of the motherboard's
physical structuren is not that strong, I'm afraid. Getting hold of
one of the actual engineers who worked on it might be your only
option. I don't know how far you want to go with it. Maybe one of the
other memebrs here might have better knowledge. Good luck.

Ben,
I'm not 100% sure because I haven't run in to your exact proble" at the promtm.  But, try this:
Make a boot disk.  DOS 3.3 is in the Files section of the group (dos33.exe).
Insert the floppy in to the drive, then boot the 1520.
You might get the the time/date message.  I think you hit F2 to get past it.
Once you get an A:> prompt, type "time" (without the quotes, of course) and you should be able to set the time.  Then, type "date" and set the date.
Then, reboot and see what happens next.
You've make good progress so far!

You'll need a Phillps (a.k.a. "cross tip") screw driver, needle nose pliers, dykes (a.k.a. "side cutting pliers"), and a soldering iron. 
At the rear of the unit, there are two rubber feet.  Remove the feet and you will see a screw.  Remove the screws.

Move the display out of the way.
Gently, yet forcefully, remove the plastic cover that surrounds the keyboard and slides under the display.  There are no screws that hold this down but the plastic catch holds it in place very tightly.
You should see the pink battery on the right side very close to the RAM SIPPs.
If you've gotten this far, you have to decide if you want to do it the "quick and dirty" way, or the proper way.
The "quick and dirty way":
Cut the leads coming from the battery as close as you can to the battery.  In other words, you want the battery leads to extend from the mother board as long as possible.
Throw away the battery.
OBSEVING PROPER POLARITY, put the new battery in place and intertwine the leads once or twice.
Solder the leads so the battery is held securely.
Replace the display and covers, and you're done.
The proper way:
You have to remove the motherboard from the chassis.  In order to do that, you have to:
    Remove the screws that hold the keyboard.
    Disconnect and remove the display.
    Unfasten the mylar strips that go over the hard and floppy drive assembly.
    Remove the screws that hold in the internal DC-DC converter (power supply) next to the hard drive assembly.
    Remove the power supply.
    Remove the screws that hold in the hard/floopy drive assembly.
    Remove the hard drive assembly.   
    If my memory is correct, at this point, only the motherboard remains in the chassis.
    Remove any screw that is holding the motherboard to the chassis.  TIP: Keep the spacers with the screws!

Hi

I created a dos boot disk, put it in the computer, and it still gives me the
Time-of-Day
Message and F2 will not bypass it, and then the
Hard drive light comes on and the computer freezes up.

I also tried holing down F but it didn't make any difference!

Hi Benjamin,

Welcome to the fold.

>From what I read, you've replaced the battery so the time circuits
are operational. When you boot up the computer, is the Time of Day
correct (in other words, is the time that you set it)? If so, then
the computer is working fine. DOS 3.3 will always go into asking if
you want to change the time of day automatically when it boots up.
Just hit enter twice and it will immediately take you to the A:>
prompt. I think that's the default for DOS 3.3. There may be a way to
autoconfigure your way past it, but I don't know what it is.

Hi

When I get the time of day message, it does not ask to set the time
and return does not bypass it. After that the hard drive light turns on, and
I can press any key on the keyboard fifteen times and after that the
computer will start
to beep every time I press a key. Pressing Ctrl+Alt+Del does restart the
computer,
But then the computer will not boot up!

Okay, Benjamin,

Then you have another problem. Again I'm assuming the battery is good
since you've replaced it. Does the POST work? In other words does the
initial memory count check out? Are there any other error messages
before you get to TOD?

My initial impression is that the computer is trying to access the
HDD now that the CMOS circuits are active again, but cannot do so.
The most likely reason is that the HDD is probably bad. But that is
not the only possibility. With the HDD light permanently on, the
computer is locked down in a repetitive loop it cannot get out of,
and the only thing you can do is reboot. But a warm reboot also does
not work, forcing you to turn the computer completely off and do a
cold reboot, which only returns you back to the initial problem. This
suggests a more serious problem which is a faulty motherboard or
faulty ROM chips. I have no way to diagnose either problem at this
point, although a replacement set of ROM chips can be obtained to
rule that possibility out.

The reason the computer beeps after fifteen keystrokes is that
fifteen keystrokes is all the computer will hold in the queue for
execution. After that it will beep you to tell you the keystroke you
just entered won't be processed.

If you can replace the HDD (very hard, or near impossible, to find a
replacement), and/or the ROM chips, then it might be possible to
narrow the problem down or eliminate it.

Best I can offer, Good luck.

Hi

This is what the computer displays

Phoenix 80286 ROM BIOS Version 3.06   10/25/89
Copyright © 1985,1986 Phoenix Technologies Ltd
All Rights Reserved

640K Base Memory, 01408K Extended
Time-of-day clock stopped ­ please set current time

It will count the memory twice, then give me the Time-of-day message,
 then it¹s about 3-4 seconds before the hard drive light comes on.

Before I replaced the battery I did get it to boot from a floppy disk,
And it would also boot from the internal MS-DOS 3.21 chip.

The hard drive seems to have a steady sound,
But it will click once in a while.

O.k. When I was sitting here it just gave me the message

Hard drive failure 
 strike f1 to continue

Bad or missing command interpreter

And then it will freeze up

Ben

Subject: Re: Grid 1520

Okay,

Basic memory check is intact. So you have an internal MSDOS 3.21 ROM
chip installed? Why do you need the floppy then? The computer looks
at any installed ROM chip as an extension of the A: drive. As far as
it is concerned, when you have a ROM ship installed, the A: drive is
1.568 MB, not 1.44 MB (with 128K unwritable). You may be having a
conflict between the two versions of DOS.

But I will assume you have removed the MSDOS 3.21 chip. What happened
is that before you replaced the battery, the computer had no data to
indicate that you had a hard drive at all, therefore it wasn't able
to check for it and did not bother doing that. I believe that is why 
you could boot up. However, once you replaced the battery, it now had
the data in the CMOS to check for the hard drive, and because the
hard drive has failed, the computer cannot boot up. It's in an
endless cycle waiting for the HDD to respond, but it's probably bad
and therefore the computer responds that it has failed and asks for
you to press F1 to continue. That tells it to ignore the commands it
needs to verify the HDD is operational. However when you press F1,
the computer still thinks there is a HDD even though it hasn't
verified it, adn it will still go to it first for the OS. Because it
can't access the HDD, it can't find COMMAND.COM which is the
operational file that's gives the user an interface to the computer
through MSDOS. That gives you the error message "Bad or missing
command interpreter".

If, when you boot up, IMMEDIATELY after hearing the computer beep
once, you must press the "F" key (not an "f" command, the actual
letter "F"), which tells the computer to read the floppy disk first.
It should then boot off of the floppy disk. if you can do that, your
problem is a bad HDD which must be replaced.

Hope that helps.

Phil

Hi

I got the computer to boot off of the dos chip and was able to set the date.

Now when the computer boots it will not ask for the time of day,
but it will freeze, and then the hard drive light will turn on and about
five minutes
later it will tell me that there is a hard drive failure and to strike F1 to
continue.

It will then boot up off of the dos chip, and I was able to run gridscan
from the dos 3.22 floppy.
It said that I have a 40mb hard drive GRID type 0 (It did not tell me that
before I
replaced the battery). Could the hard drive be O.K, but have been erased by
the
people that had it before me?

Also, I still cannot get the computer to boot from a floppy, hitting F does
not make a difference

The failure is due to the very very low level of Dallas cmos battery.

I had the same problems..... i hacked the dallas integrate with an
external battery and now it's OK.

Nell'anno 1969 è bastata la potenza di calcolo di due Commodore 64 per
mandare con successo una navicella sulla Luna.

Nell'anno 2007 è necessario un Pentium 4 Dual Core a 3 Ghz e 2Gb di
Ram per far funzionare Windows Vista.

(Qualcosa deve essere andato storto).

Replaced, how do I replaced thr dallas one?

Nell'anno 1969 è bastata la potenza di calcolo di due Commodore 64 per
mandare con successo una navicella sulla Luna.

Nell'anno 2007 è necessario un Pentium 4 Dual Core a 3 Ghz e 2Gb di
Ram per far funzionare Windows Vista.

Hi

Thank you, but that¹s not my problem. My grid case has a cmos battery,
not a Dallas RTC.

Anybody else have any ideas about getting my hard drive to work?

Ben,
The hard drive is probably bad.  It is a mechanical device that is close to 20 years old. 
There could be many things wrong.  Here are a few possibilities:
The lubricant in the bearings could have leaked out.  Or,
The bearings ceased.  Or,
The motor cannot maintain the proper RPM.
One thing is to try boot to DOS and see if fdisk "sees" the hard drive. If it does, set up the partition, and then format it.
Let us know if that works.
-Shawn

Hi

I got the computer to boot off of the dos chip and was able to set the date.

Now when the computer boots it will not ask for the time of day,
but it will freeze, and then the hard drive light will turn on and about five minutes
later it will tell me that there is a hard drive failure and to strike F1 to continue.

It will then boot up off of the dos chip, and I was able to run gridscan from the dos 3.22 floppy.
It said that I have a 40mb hard drive GRID type 0 (It did not tell me that before I
replaced the battery). Could the hard drive be O.K, but have been erased by the
people that had it before me?

Also, I still cannot get the computer to boot from a floppy, hitting F does not make a difference

Okay,

Basic memory check is intact. So you have an internal MSDOS 3.21 ROM
chip installed? Why do you need the floppy then? The computer looks
at any installed ROM chip as an extension of the A: drive. As far as
it is concerned, when you have a ROM ship installed, the A: drive is
1.568 MB, not 1.44 MB (with 128K unwritable). You may be having a
conflict between the two versions of DOS.

But I will assume you have removed the MSDOS 3.21 chip. What happened
is that before you replaced the battery, the computer had no data to
indicate that you had a hard drive at all, therefore it wasn't able
to check for it and did not bother doing that. I believe that is why
you could boot up. However, once you replaced the battery, it now had
the data in the CMOS to check for the hard drive, and because the
hard drive has failed, the computer cannot boot up. It's in an
endless cycle waiting for the HDD to respond, but it's probably bad
and therefore the computer responds that it has failed and asks for
you to press F1 to continue. That tells it to ignore the commands it
needs to verify the HDD is operational. However when you press F1, 
the computer still thinks there is a HDD even though it hasn't
verified it, adn it will still go to it first for the OS. Because it
can't access the HDD, it can't find COMMAND.COM which is the
operational file that's gives the user an interface to the computer
through MSDOS. That gives you the error message "Bad or missing
command interpreter".

If, when you boot up, IMMEDIATELY after hearing the computer beep
once, you must press the "F" key (not an "f" command, the actual
letter "F"), which tells the computer to read the floppy disk first.
It should then boot off of the floppy disk. if you can do that, your
problem is a bad HDD which must be replaced.

Hope that helps.

Phil

Hi

I ran fdisk from the dos 3.22 floppy disk (I still can¹t boot from a floppy
disk)
And it gave me this message

Error reading fixed disk.

Does this mean that my hard drive is dead, or that it can¹t read from my
floppy?

Also, how do I take out the dos chip, I was thinking that there might be a
conflict
between that and the floppy.

HHmm.. "Error reading fixed disk" seems to imply that the computer detects the hard drive, but can't read or write from the drive.
It appears that the hard drive is defective.  I don't think there is much you can do for it.
The DOS chip should be on the left side, between the keyboard and video display.  There might be a hinged door.  Just pull the chip straight out.

Ben,
I don't know how new your Dell is.  If it is built in the last couple of years or so, it may not use IDE to talk to the hard drive.  It may be the newer AHCI interface.  It might be a BIOS setting on your laptop.  If it is AHCI, DOS 3.3 won't be able to talk to the hard drive.  Also, if your hard drive is SATA, then it won't be seen by DOS 3.3.
The hard drive is under the floppy drive.  To remove it, (I'm doing this from memory, so I might forget a step) you have to remove the 4 screws that hold it down.  Remove the 3 mylar "strips" that run over the drive assembly.  The connectors are near the RAM.
Then, remove the mylar strips that plug in to the motherboard and the drive assembly.  Finally, you might have to remove the two screws that hold down the DC-DC converter (the small brick looking thing next to the drive assembly).  After the screws and mylar have been removed, you should be able lift the drive assembly out of the computer.  If you turn the assembly upside-down, you wil see the hard drive.  I think there are 4 screws that hold it in the drive assembly.
The 3 mylar strips that go over the drive assembly only extend the serial and parallel connectors to the rear.  They are not necessary to reconnect if you just want to test.
Good luck,
-Shawn

Hi Ben,

Your Dell is far too advanced a computer for DOS 3.3. The HDD of the
DELL has technology that would not be recognized by such a primitive
OS as DOS 3.3. That's why it wouldn't recognize it on Fdisk. You can
go to various web sites and download the latest independent DOS
before they stopped upgrading because the OS world had developed into
Windows by then, and that latest full DOS is version 6.22. Just
Google it and you should be able to find a site that will let you
download it.

But to be honest I don't think it will make any difference at all.
Chances are very strong that you have a bad HDD. The GRiDcase 1520
was limited to only six possible drive configurations that it will
recognize, only three of which were actually made and usable (the
other three were test configurations I believe). These are the only
drives the computer will see short of altering the ROM BIOS chips
themselves (something I and Shawn have done, BTW) because this
information is hardcoded into the ROM BIOS chips. These drives are
all Conner hard drives from the early 1980's which are the 20 MB, 40
MB, and 100 MB drives. These drives were not that well made and the
majority of them will not last twenty plus years. Conner was
eventually bought out by SeaGate in the 1980's, so you can't really
go back to the company.

Everything you have reported points to the hard drive being bad and
unusable. It has been the most frequent problem we run into apart
from the dead CMOS battery. Trying to find another one of these old
drives is extremely tough. You would have to go to old vintage
computer parts stores and junk shops and scrounge around for these
drives (I know. I've done it.) I have occasionally been successful in
finding a usable Conner drive of that era that could substitute for
the bad one. If you find a compatible HDD with a compatible pin
configuration (which is different from today's HDD. That's because
the protocol that the computer uses to communicate with the HDD is
the old MFM protocol [modified frequency modulation] which is a
precursor for the present day IDE protocol.), it may be possible to
program new ROM chips to let the computer accept it. As I've said,
both Shawn and I have been successful at doing that. But short of
that, it will be nearly impossible for you to replace that HDD.

This is a page which shows the different Conner Hard Drives:

http://www.computerhope.com/hdconner.htm

Pretty much, the series you can use are the CP series. I would
recommend using only a HDD under 512 MB due to limitations of the
operating system and the computer. It is only an 8 bit machine after
all. The original drives for this computer which require no
modification for the ROM chips are the CP3024, CP3044, and the
CP30104. However, many of the other CP models will work in the 1520
with modification of the hard coding in the ROM BIOS chips. I have
been succesful in using the CP30174E for example. Some of the CFS
series hard drives can also be used. Both Shawn and I have adapted
the CFS420A for example. The other CF models are too advanced and
cannot be used, I believe. Be aware though, some of the CP models may
not be adaptable due to pin configuration, but I cannot tell you
which ones exactly. Also some of them are full height, which you also
cannot use.

Unfortunately, those are your only choices. All you can do is try to
find a replacement for the hard drive. As I noted, it is almost
impossible to find an exact replacement. You may be left with trying
to adapt another Conner HDD from the available list, if you can find
one that works, and even those are very difficult to find. If you do
find one, you will then have to burn new ROM BIOS chips on EPROMS
using an EPROM burning device, many of which you can find on Ebay or
for sale otherwise. Shawn has listed the instructions for altering
the hard code on the ROM BIOS to allow the computer to recognize the
new drive, and these instructions are in the files section.

I'm sorry it's so difficult. But we have all been through these
problems here on the forum and hashed them out, trying to find
solutions. This is the best we have come up with so far.

Best of luck to you.

Phil

I'm not sure if DOS 3.3 will see a FAT32 drive or, for that matter,
anything bigger than 500MB.  If you want to try a sanity check you
might find a Win98 machine someplace and make a boot disk with that
(format & system files)  Add fdisk from the windows command folder and
that should see the Dell HDD OK.  If you can find a way to boot the
Grid from that disk it should give you an honest opinion on the drive.
    Getting it too boot from the floppy may involve looking for that
config 15xx utility though.  IIRC there is a routine in there that has
to be run to get it to boot from the EPROM... since you've just
blanked the CMOS and it boots from the chip maybe that's the default
mode for your bios (just guessing) and, if it is, you might have to
run the utility to change where it looks...

I'm just guessing here, mind you...don't take this as gospel.  And, of
course, I agree that the old Conner drive is probably bad...most of
them are at this point.     A couple years back I found one in a
surplus store that appeared to have no bad sectors!  It didn't stay
that way for long though.

I've found myself thinking about these old hard drives...they were
made way before drives reported their configuration to the bios
weren't they?   If you simply put in a drive with more sectors, more
heads..etc what are the chances that the Grid would read it as the
smaller drive that it was expecting to find?   Maybe I'm not thinking
clearly about this...

Phil(?),
Good thought, but no. 
In the BIOS, there is a 61 or 62 entry table that contains Cylinder, Heads and Sector (a.k.a. CHS, a.k.a. "drive geometry") numbers for different drive types.  These table entries also contain the pre-comp, LZ and other things I can't remember.  If the drive doesn't match these values, the computer won't recognize the hard drive.
There are several questions that I have that I haven't had the time to answer.

Hi, Shawn,

Actually no, it was androgenoide who wrote that last post. I agree
though about the money you could spend. I found a used PB-10 EPROM
programmer on Ebay for about $25, then bought some used ROM 28c128
EPROM chips for about $1 apiece. That was what I was able to do. I
spent another $25 on an ancient P1 computer and attached the burning
unit into a PCI slot and loaded MSDOS 6.22 on it. The only thing I
have on this unit is the program to run the programmer to burn the
EPROMS. It's a little annoying to use because you have to run it
strictly from DOS without much of any kind of GUI, but it works fine,
and it was cheap overall.

      As to the hard drive table, I believe it probably doesn't
matter where you place the information, I think the BIOS will read
the entire table and try to match it to what it's reading on the HDD.
If it finds a match then it will pass the code to recognize the hard
drive and connect the I/O  parameters into the computer. If it
doesn't find a match, it will simply pass the code of no
recognitiion, and simply not see the HDD.

Hallo Shawn,
I don't know if there's any possibility to use other hard drive

I would like to change the hard disk with a bigger one but I  haven't 
the Eprom  programmer  to burn the  two eproms.

At this moment I'm working on my Grid 1530 and on the possibility to 
connect it to my router Adsl for Telnet connection. I found on the Web 
the Crynwr Packet Driver with the TCP/IP protocol for the GRiD ethernet 
pod (the ethernet cartridge is connected to an AUI transceiver with rj45 
output and with a rj cable to my router) and Minuet as Telnet terminal 
software. The system is working perfectly.

The current  setting for the tcp ip driver are 0x60 2 0x360  0xc400

  Racal-Interlan (Formerly Micom-Interlan) NI5210
                        usage: ni5210 [options] packet_int_no 
[hardware_irq [io_addr [base_addr]]]        
               The NI5210 driver requires three additional parameters --
          the hardware interrupt number, the I/O address, and the memory
          base address.  The defaults are 2 and 0x360 and 0xd000

I have upgraded  the GRiD  with a Cyrix CX486drx2 and Cyrix Fasmath

The problem with me is that once I pack things up, it's a year or two before I take it back out again.
Just to keep everybody up to date, I have been working on my Grid in my spare time since the 4th of July holiday weekend.  My goal is to get it to boot from compact flash.  I've burned about 8 sets of BIOS EPROMS trying different options.  None of my attempts have worked.  It is a good thing they are erasable!

Paolo:  I have not forgotten about the Gun Sentry program.  I will work on the program after I figure out how to get my 1520 to boot from compact flash.

Andrea and all,

If you are interested in DOS networking I have a wonderful little IRC 
client for DOS that should run very well on a machine like the Grid.  
You only need the packet driver - the TCP/IP part is built into the 
program.  See http://www.brutman.com/Dos_Networking/IRCjr.html for the 
details.

It runs well on a PCjr, so a Grid should be overkill.

Shawn,

Refresh my memory again.  Are the parameters for the three drives types 
that represent the Connor stored in BIOS?

I'd have to see a BIOS and spend some time disassembling it to know what 
it is doing.  Here is a theory ..

IDE drives have an 'identify drive' command that will return back a slew 
of parameters and strings.  There are some vendor specific extensions.  
It is possible that the Gridcase knows that it should have a Connor 
drive, and it is expecting a specific response in the data returned by 
the identify drive command.  What gets returned determines which set of 
parameters in the drive table gets used.

If this is the case, this isn't just a matter of patching the BIOS to 
find the drive tables and change them.  You're going to have to alter 
the code that examines the output from the identify drive command and 
dumb it down.  It's just some ASM that should be easy for a more 
experienced x86 programmer to alter.

Hi, Mike,

You are correct. The parameter table for the the hard drives are
indeed listed in the BIOS. There are two different tables that have
to be addressed. One table lists the actual paramaters of the
physicial hard drive. The other table lists the name and model of the
hard drive. Bit of these have to be adjusted. Shawn has the
instructions for doing that in the files section.

As to your theory, we have to remember that these are not IDE drives,
they are MFM (modified frequency modulation), the precursor to IDE
which had not yet arrived at that time, although that may not make
any difference. It may be that the identify command is the same
nonetheless and what you state is still true, that just modyfying the
parameter and name tables is not enough for the computer to recognize
Non-Conner drives. I have actually gotten as far as getting a program
that decomplied the BIOS hex dump down to a form that is readable as
assembly instructions, but I simply don't have enough experience with
assembly language to properly do the job. I messed with it a little
years ago, but that was all, and I don't really remember it anymore.

I am sure that they are IDE drives.  The Connor CP3044 and the other 
drives that you guys are cursing at are definitely IDE drives, not MFM 
drives.  MFM drives don't have the intelligence to respond to an 
'identify drive' command.

Assume that the BIOS is sending that IDE command, and is getting a model 
number string back from the drive.  That's probably how it decides which 
table entry in the ROM to use.  The data from the drive might be encoded 
in binary, which would make things difficult.

The sequence to look for is the Identify Drive command (0xEC) being send 
out the command port to the drive.  That will be followed by a single 
sector read with the first 98 bytes or so being significant.


Shawn - it should be possible to write something that does the identify 
command against a drive to see what the magic response string is.  
Sending the 0xEC command is easy ..  I'm just drawing a blank on how the 
data gets read back in.  You've got to read all 512 bytes from the drive 
through a single register.  (The BIOS tech ref for an AT should have a 
sample to look at, as it is a superset of the MFM command set.)

 This goes back to something I suggested long ago, which is a program which is like the varous program overlays put out by major HD manufacturers to fool the BIOS into accepting larger drives than generally accepted. I have several HDs whose specs are entered after the BIOS and before the OS starts. The SCSI pod also directs the BIOS to access certain memory locations containing it's specs and connectons. Why couldn't an overlay program accessed before the OS do the same thing ? That would make unnecessary the need to reprogram the BIOS chps and could even be burnt along with an operatng system into the 2 eprom chip vacant slots which are available and load before any Disk input if one wanted and/or had the equipment to do so.

Phil,
I meant to address this as well.  The drives are IDE drives.

Hello,

As the title says my GridCase 1520 refuses to power on. I have
determined that the problem lies with the plasma display, I believe
there may have been a post/thread on how to fix the problem at one
point. However, after going through each and every post from the
beginning, I have come up with nothing so far. Any help is appreciated.

Hello Nick.
OK, I need a little more information.  You said it "refuses to power on."  What happens when you first turn the power switch to "on"?  Do you get any indication that the Grid is trying to power up?
Inside the 1520, there is another power supply.  It is a DC to DC converter and it is located towards the rear of the hard drive assembly.  The DC-DC converter feeds power over to the display.  It is possible the failure is actually in the converter and not with the display.
Another thing to check is the DC power supply feeding power the the Grid.  It has to be supplying 16 volts and, if you have a hard drive, about 2 amps to get the hard drive spinning.  Once it's up to speed, the current usually will settle down to about 1.25 to 1.5 amps.  If you have no hard drive, the current will usually settle down to about 750 mA.
Good luck,
-Shawn

Hello,

When the plasma display is connected to the graphics card and
everything the system will make a faint click sound when the system is
turned on. Without the display hooked up the system will start up as
normal albeit with a few error codes due to the modem board and such
being removed. I am using the standard Grid 15xx internal/external
power supply. I was thinking it had something to do with the power
supply for the plasma screen, but I was sure exactly what it was or
where it was located.

Nick,
The display power supply is modular.  In other words, if it is bad, you can replace it.  BUT, you cannot swap it with a power supply from a LCD model.  Well, you can, but it won't work.  The plasma display needs more current.  I'm doing this from memory, but if I remember it correctly, the LCD display has a 20 watt power supply.  The plasma display has a 48 watt power supply.
As you mentioned earlier, it is still possible that the display itself is bad and the power supply is good.
Good luck,
-Shawn

Has anyone had any luck doing a bios mod to add  a different hard drive

Hi, klyball,

The 1520 method should work on the 1550SX. After all the 1550sx is a
386 machine just like the 1530, and the BIOS's should not be hardly any
different, really. However, I know from the testing I've done that some
o the old Conner models simply won't work with the GRiD's, whereas
others will. I don't know why, or which ones except by trial and error,
but that seems to be the case. I have adapted a cp30104 before
successfully to a 1520. Never tried a CP30064.

I understand from reading the above posts that only conner drives will

The bios mod will only work with conner drives ,is this the case? .

could the bios be fooled to see other types of hard drives?

here is a bit of disassembly around the first hard drive table.

i need to find the area where the hard drive is initalized.

if there is a way to fool the bios to think the new drive is a conner

Yes, the GRiDs were designed to only use the Conners, however I don't
know that they won't take other drives with compatible physical
connections. It's just that none of us here have ever tried it. In
theory, you should be able to get the BIOS to accept another drive as
long as you entered the appropriate information into the drive name
table and drive parameter table as per Shawn's instructions. Since
the procedure was really worked out by him, he might be able to
answer your question getter than I can.

Klyball,
Sorry for my delay in responding.  I had a busy weekend, then I had to play catch-up at work on Monday.
You are farther along than I am.
My answers to your questions are, "I don't know."
 
I was able to get another Conner drive to work with my 1520.  I am in the process of trying to get my 1520 to boot from a Compact Flash (CF).  I'm kind of on a detour right now, however.
 
I too am trying to disassemble to BIOS.  But I am lacking basic microprocessor knowledge.  I bought a book on 80286 and -386 assembler.  I've started it, but it's hard to stay motivated to read through it.
 
I am curious about your set up.  Are your BIOS EPROMS soldered to the motherboard or were they socketed?
What equipment did you use to read the EPROMS?
What program did you use to read the EPROMS?
How did you deal with the checksum?  In other words, when you re-assembled the BIOS and got the different checksum, did you modify the text at the beginning of the file to get the checksum to work out to the original, or did you find the checksum value in the file and modify it?
 
I guess that's it for now.
Thanks for the info.
-Shawn

Hi Tim,
Welcome to the group.
I'm a Linux novice, so you'll have to have patience with me.
I'll have to look to see if I have the original boot disk.  I have been booting my 1520 from a MS-DOS 5.0 disk.  I also have a MS-DOS 3.3 disk.  I can image one or both of those.
Then, you can ftp them from my ftp site: shawnerz.homelinux.org.  Login as griduser.  The password is the same as the username.
If you like, there is a tarball of contiki OS.  There is another folder containing mimix.  Both versions are supposed to run on a 286.
I haven't had the time to play with those OS's.  My plan is to get the 1520 to boot from compact flash, write a Grid Sentry program that I promised somebody a year ago, and then play with Linix on the Grid.
Maybe, one day, when I hit the lottery and have all this free time, I'll have the time to play with my Grids... One can dream, right?

Sadly, I must do all my net from a palm pilot, and cannot FTP from it.

However, thanks for the offer.  Three questions, though:  What is contiki, does mimix = MINIX, and if so, can you eMail the MINIX disks?  That would save me a lot of work (cross-compiling ELKS and Nano-X, building a boot disk, many other cross-compilings as well...)

HI

Thanks for the reply,

Chip reading and burning i use a mod-emup(all-03) universal
programmer in a old 486dx4 100 sbc, it has its own software that does
all the old chips tests ram and logic and some newer ones to.

I manipulate the files with winhex

disassemble with freeida43 and a old version of hiew

I'm no assembler expert buy any means, i learn buy trial and hours
using my trusty microsoft macro assembler 5.1 reference book (if you
can find one it's real handy and saves reading all the assembler
books.if all your doing is trying to trace code.

The 1550sx has 2  socketed 27c512 eproms
i at first managed the checksum with the first copy right message but
it didnt work ,but found a copyright message near the end of the code
that works.

the 1550sx bios is layed out a little different but i think it is
using the same identification to set the hard drives.

I have tried 3 diffent drives using many different modified setting
in the bios table no luck. I must find what is being read to
determine that the proper hd is in.

i ran a prog called wdtblchk and it shows every hard drive i hook up
to the grid

it says
drive 1 found directly
drive not found with int 13h

there must be a simple check (serial number,name code )that checks
the drive first before checking the cyl heads sec ,so its kicking out

i'm going to keep analyzing the bios and going to try and look at the
cmos memory if i can, it should be loaded into memory somewere.

i think it should be a easy fix to jump the drive check if i can pin
it down ,letting us use any drive buy any manf.

or i could be just not setting up the name or table correcty
i ussually always do things the hard way.

i will move to a 1520 if i hit a brick wall with the 1550sx,  the
bios file is less cluttered and alot smaller but i have the 1550
ripped apart now.

i will keep you posted on my progress.

i'm going to try to mod a drive table above #16 just for the heck of
it i've been modding the first 3 only .Worth a shot

The recent and prior posts and links have some great info!  I rescued
a 1530 from the recycle pit, and I have gotten a Win98 boot disk to
get a DOS command line.  The Connor Drive is good, but the 1530
doesn't recognize it.  I hooked it to my current desktop (XP) and i
think I messed up the FAT partition (forced a format and OS load on
me.)

Just want to be sure on a couple things.

1. There is no F2 or CTRL-S or other key to get into BIOS. The bios
is fixed and either runs or not.

2. The Dallas BIOS chip has a self contained battery.  And it is
dead.  There are photos (I looked over the Italian link) on soldering
in a battery, but I have found no text explaining the procedure. Is
it hiding around the group?

3. Will I have to reprogram the BIOS chip?  I haven't played with
Assembly since 1982, but I can figure it out.

I have a power supply in the bay. It won't power the grid while in
the bay (I'm using a universal adapter right now), but it puts out
15+ VDC so I think I need the three pin cable to plug it in to the
case.  Anyone seen where that weird 3 pin cable is available?

Thanks

Hi, Dave,

I'll try to help you out here..

Yeah, you used a WINDOWs 98 disk to try and reformat the drive. Not a
good move I'm afraid. WINDOWS DOS (7.22) is far too advanced and the
hardware of the GRiD cannot work with it. The way it sets the drive
parameters to be recognized are unintelligible to the GRiD hardware
and BIOS. You will have to start from scratch and I would recommend
going to DOS 3.3 (and the original GRiDDOS 3.3 would be better, but
regular DOS should work) to reformat the drive, if you can still get
it to be recognized. You may have to low level format the drive to
get it to work.

1) You are correct in that there is no F2 or CTRL-S or other key to
get into the BIOS. That's because there is no BIOS program at all to
access. These computers are so early in development, that BIOS
manipulation by the user was not yet felt needed. Thus the BIOS was
programmed into the chips as is, and that's it. That's what you have
to work with. If you want to change it (very much at your own risk
and you should be pretty good at asssmebly language programming on
the 386 processor instruction set platform), you would have to
physically do that with the appropriate macroassembler programs and
reburn a new set of BIOS chips for the computer.

2)There is a method developed by an individual in Germany for
attaching a new battery to the DALLAS RTC chip. The explanation(s)
with photos on how to do this is in our files section here on the web
site. I performed this mod myself a few times.

3) So far, the only reprogramming we've done here is to change the
hard drive name table and hard drive parameter table to accept a
different Conner hard drive. I've done it with several of my 1530's
and 1520's, as has Shawn. Nobody on the site, that I know of, has
tried altering any other part of the code. It's been a very long time
since I've done any assembly work on that platform as well, and I
don't remember it anymore. But it would be cool if someone was able
to reprogram the BIOS to adapt better to what's available today. But
the limitations of the computer, such as a 128 Kb limit on the chips
is definitely a challenge.

4) The standard power supply for these computers are a 16.25 volt/3.7
amp 60 watt power supply. These are not too rare and you can find
them on ebay and other related sites. The 3-pin cable is indeed
unique. I myself have not been able to find it anywhere either.

I hope that answers some of your questions. Good Luck.

Phil

Hello Dave, Welcome to the group.
It's good that we've gotten a few new members that are breathing life back in to the group.

To answer your questions:

You are correct.

>2. The Dallas BIOS chip has a self contained battery.  And it is

I'm not aware of an Itialian link, although Andrea (another member of the group, in Italy) did a mod where the RTC battery lines were extended and a replacable cell was added.  There is a German link here: http://www.mcamafia.de/mcapage0/dsrework.htm

>3. Will I have to reprogram the BIOS chip?  I haven't played with
>Assembly since 1982, but I can figure it out.

That depends, what are you trying to do?  If you're trying to boot from anything other than a Conner drive, then yes, the BIOS will have to be modified.

>I have a power supply in the bay. It won't power the grid while in

I think it's a Hirose connector.  I've never looked it up.  I'll add it to my things to do list.
I think the 1550 uses the same connector.  Before I gave up on the 1550, I used to two small nails inserted to the connector.  Then, I attached one side of aligator clip leads to the nails and the side to my DC power supply.  Wasn't exaclty the safest set up, but it worked.

I hope that helps.

1. There is no F2 or CTRL-S or other key to get into BIOS. The bios
is fixed and either runs or not.

2. The Dallas BIOS chip has a self contained battery.  And it is
dead.  There are photos (I looked over the Italian link) on soldering
in a battery, but I have found no text explaining the procedure. Is
it hiding around the group?

3. Will I have to reprogram the BIOS chip?  I haven't played with
Assembly since 1982, but I can figure it out.

I have a power supply in the bay. It won't power the grid while in
the bay (I'm using a universal adapter right now), but it puts out
15+ VDC so I think I need the three pin cable to plug it in to the
case.  Anyone seen where that weird 3 pin cable is available?

Thanks
Dave

At_Hound,
By your email, I'm not sure if you have the answer to your question, or if you're still not sure.
If you're still not sure, there are two reasons to drill.
1) IIRC, pins 16 and 20 do not extend through the bottom of the RTC chip.  As a result, you have to drill in from the side to get to the pins.
2)  The connection to the internal battery has to be broken.  This prevents the good, external, battery from discharging through the weaker, bad, internal battery.

I hope this helps.

My question is:

Has anyone put in a harddrive other than a conner using bios mod ?

If yes than i am doing it wrong somehow.

If no then i think i have a idea how to make it work.

I believe the real drive table is encryted in the bios and they only
set it up for a few different conner drives depending on the model.

i manually set up the cmos with some drive perameters,but when i
restart the machine the cmos entry that sets the drive type is reset
to 00 but the drive perameters suprisingy remain in cmos. Half the
battle

Now the trick is to find the routine in bios that is checking the
encrypted drive table and jump it.and or stop the bios from writing
to the cmos that is clearing the 12h and 19h entry.

i've disassembled a lot of the code and am narrowing down the areas
to test,but with out a way to debug the bios code it's hit and miss
also i only have a couple of chips, so erasing,assembling ,programming
 is a long proccess to try out one code change.
I will update on my progress but it will take a while.

I'm going to Zen the code for while before i test.


Why am i doing this? i don't really know.But.....

Klyball,

In answer to your question, nobody here has ever tried to put in 
another HDD except a Conner. I actually have a couple of usable
samsungs and seagates I thought about trying, but I had enough
Conners that I didn't ever try it myself. So the answer is no, it
hasn't been tried. But if you can solve that riddle, that would be
great, and it would be a great addition to the forum.

Subject: Re: [RuGRiD-Laptop] 15xx hard drive

Klyball,
I really appreciate the work.

The question I have is, why encrypt the drive table?  The date code on the BIOS is circa 1988.  Why bother going through the trouble of encryption?
It's more likely that there was an XOR value or an AND value the data was combined with.  But again, I come back to the question: why?
Error checking?  A primitive means of locking Grids to Conner drives?

I'm not clear on what you're doing.  You said:
>i manually set up the cmos with some drive perameters
I assume you're burning new EPROMS with custom values.  For example, changing the sectors/track value from 63 to something like 24.

>but when i restart the machine the cmos entry that sets the drive type is reset to 00
Here's my confusion: Do you mean the text field?  Like "CP3044" or "CP322" or is there another field?

>but the drive perameters suprisingy remain in cmos
If I'm correctly understanding what you're saying, this is expected behavior.  As I understand the boot sequence, at boot, the contents of the BIOS chips are read in and executed.  Using my example, you changed the 63 to 24 in the EPROM.  Boot the computer, the 286 reads in the EPROM data.  Now you reboot the computer.  It will dump the currently held data and read in the EPROM again.  So, the '24' will still appear to be held in RAM.
I must have missed something because you are obviously very talented.  You've taken a different approach and gotten much further than I have.  If there is anything I can do to help, just let me know.

The erasing, assembling, programming, testing cycle is a pain in the butt.  I know your pain.  I basically have to take over our kitchen table when I'm doing this.  I've got the P1-633 with a monitor, power supply, UV eraser, EMP-20 programmer, spare EPROMs and the Grid in 3 sections all laid out.

I did find a guy selling 27C128 emulators for ~$200.  But, I'd need 2 and $400 for this project is a little too much.

I'm going to email you some pdf's of the service manual.  Mike B. found these sections useful when he took a look at this problem.

Again, I really appreciate your help on this.
-Shawn

Trivia
The GRiDPad 1910 is basically an extremely portable PC-XT. It has a 640x400 backlit Monochrome CGA display. It has 2MB of system memory, and often came equipped with a 20 MB 2.5" IDE disk. The pen system is capacitance-based, with a wired stylus. There is a 6-pin micro-DIN XT keyboard interface. Audio is limited to the usual PC Speaker support. There is one serial port expressed on the unit, and expansion for a modem, which came in 2400 and 9600 bps flavors. There are two ATA-FLASH slots on the unit, which are used strictly for storage. There is also an expansion bus connector on the bottom of the system, which includes at least a keyboard connector, a parallel port, and a floppy bus. There are buttons F1 through F5 and a sleep button on the unit, as well as a hard power switch. Power is supplied via Ni-Cad battery packs.
This machine was used primarily for inventory purposes and the like. Apparently it was used within Chrysler for that purpose, and by the United States Army. The military specified more rigidity and durability from the case than the civilian version provided, and so GRiD made the case out of magnesium. They were never sold to the public that way, but occasionally a unit will slide out of the hands of the military.

 I have a few pictures, some with labels, and I will post these in these on the web-site.
Thanks for the reply,         Chris.

The pdf files of the service manual that Phil was kind enough to provide are still on my ftp server.  The other OS files are there too.
With that being said, I've always just gone to groups.yahoo.com and selected from my list of groups on the left side of the screen.  I've never had a problem with going directly to groups.yahoo.com.

Hi, Andrea,

The methodology by which to alter the BIOS is spelled out by Shawn in the files section. I myself have my primary 1530 loaded with a CFS420A and it works very well. Look in the files section for the text file by Shawn named "1520 Hard Drive Reprograming Instructions.txt". This will take step by step into how to alter the BIOS code to allow the computer to recognize the CFS420A. Of course you will have to burn 2 EPROMS with the altered BIOS adn then insert them in place of the OEM BIOS chips on the machine in order to get this to work. You will need an EPROM burner to do that. Good luck.

Lawrence (and Andrea),
I have to answer your question in two parts.

>Is there anyone in the forum who has a burner and would be wlling to burn the chips

I'm willing to burn the chips.  I do not have a patched file for a 1530.  I am about 75% sure I can do it by copying the information that I used for my 1520 and then changing the checksum.
The problem is I am overseas and will not return until mid-May.  Because I used the CFS420A in my 1520, I'm confident the same values will work in the 1530.  If I am the one to do this, your project will have to wait until I return to the US.


>which depends of course on the HDD one wants to use?  Are there any limitations on the HDDs one can use?

This is more problematic.  I do not understand what the BIOS is doing when the Grid is powered up.  I've run the BIOS through a dis-assembler and I some routines have been identified.  But, I don't fully understand what the BIOS is instructing the processor to do.  I also do not understand when a register is set, what piece of hardware is it controlling?  I also don't understand how the checksum is computed.

I think I was extremely lucky to have used a Conner drive that was under 512 MB.  I think if I would have used anything else, the process would not have worked.
One other item I was lucky: the IDE pin placement on the CFS420 is the same as the CP344 family of hard drives.  If you grab any other off-the-shelf IDE drive and compare the two, you will see that the pins are in a different place.  This will complicate drive placement.

My ultimate goal is to get the Grid to boot from Compact Flash.
My guess is that this will happen after I win the lottery and I have a bunch of free time on my hands.... ;-)

Is there anyone in the forum who has a burner and would be wlling to burn the chips, which depends of course on the HDD one wants to use ? I for one would be wililng to pay for this service, and I'm sure many others here would also be willng to do so.  Are there any limitations on the HDDs one can use ?

Hi, Andrea,

The methodology by which to alter the BIOS is spelled out by Shawn in the files section. I myself have my primary 1530 loaded with a CFS420A and it works very well. Look in the files section for the text file by Shawn named "1520 Hard Drive Reprograming Instructions. txt". This will take step by step into how to alter the BIOS code to allow the computer to recognize the CFS420A. Of course you will have to burn 2 EPROMS with the altered BIOS adn then insert them in place of the OEM BIOS chips on the machine in order to get this to work. You will need an EPROM burner to do that. Good luck.

Lawrence, Shawn, and Andrea

I too am in the middle of moving. I am living in an apartment where I am working now in West Texas and everything that was in my house from the Dallas area is in storage. I actually have the altered files you can use to burn the new EPROMS, but not with me. It's all in storage and I can't access them as it's on the old P1 computer I use to run my EPROM burner. I can't get to it until I actually get a new house, which may take a while considering the way the market has been going. So I'm afraid I can only tell you that I followed Shawn's instructions exactly as he wrote them, and it worked perfectly for my 1530. So he should have no trouble being able to do that for you.

I will toss in a word about what to consider in a drive except for the 
pinout, which is mentioned elsewhere.

Early disk subsystems designs had a  limitation in the amount of data 
due to bios assumptions as to how many sectors / track, tracks / 
cylinder and cylinders there could be on a drive.

The IDE design cast these in stone early on because all the IDE design 
was originally was taking the disk controller electronics out of the 
computer backplane and integrating it into the disk assembly, and 
connecting up a cheaper parallel bus via a 40 pin ribbon cable to the 
combined drive / electronics package.

Anyway, later drives integrated a method for sizing drives that stopped 
at 33gb, 133gb, and basically unlimited.  I don't know if the high 
capacity drives will operate with the very old bios settings because of 
the earlier assumptions on drive geometry.

I changed the bios of my Compaq portable III in a fashion similar to the 
one mentioned here, as it has a dual eprom bios with the same sort of 
checksum to use 512mb drives without any more than finding and altering 
the drive tables, and recalculating the checksum.

I am going to guess it will be the luck of the draw to get compact flash 
to work, though its heritage is such that smaller devices are still 
common, and that may help where the disk drives have gotten so much 
larger that the small capacity operation was dropped from them.

Just to shed a little hope on the topic ...

There are two people over at the vintage computer forums (www.vintage-computer.com/vcforum) who have been working on an 8 bit IDE card for 8 bit machines that is capable of using modern IDE drives.  They have been pretty successful with the prototype cards.

Of particular note is one member (screen name is Hargle) who did the BIOS coding work.  There are people out there who can still modify or extend the BIOS of old machine.  Given time, getting a CF card in a Grid should not be a significant challenge.

Unfortunately, we only have one Hargle. ;-0

 One of my other favorite portable machines is a Dauphin DTR. It's HDD interface is PCMCIA capable and hacks have been done to use existing adapters to use CF wth them.
 
 Is the PCMCA protocol only BIOS and software based, or is there a Hardware component involved ?

Hello and thanks for reading and the help..

I got this gridcase 1550sx 386 laptop..

when I turn it on I see the phoenix bios information loading and it beeps then the trouble starts.

I get the following:

HARD DISK FAILURE

Press F1 to continue

then I press F1 to continue and nothing it just hangs in there and the screen goes on and off ....

I try to put a floppy on the internal floppy drive and nothing happens...

How do I get into the bios on this computer??? or how do I get to run it from a floopy that way I can at least know that works also...

Thanks in advanced

Miguel,
I tried to respond, but for some reason, yahoo deleted my email. :(
It is not uncommon to have a hard drive failure.  The laptop has probably sat for a long time.  This causes the platter assembly to stick.  Another problem is the bearings will lose their lubrication.  So, the end result is the hard drive fails.
Another possibility: are you sure there is a hard drive in the laptop?  It's possible that the hard drive was removed.

The screen going on and off is weird.  The internal power supply could be dying.  What external power supply are you using?  The Grid needs to be fed with 16V at about 1.5 amps.  Once it has booted, the voltage can drop down below 11 volts and the Grid will still function.  But to boot, you need to have 15 volts or above.
It's also odd that you can't boot from floppy.  That makes me wonder about the power supply.

Getting in to the BIOS.  Grid are not like a newer computers where you hit something like F2, or F10 or something to get to a BIOS setup screen.  Go to the Files section of the group and look for conf1550.exe.  Once the computer has booted, you can run the program to configure the BIOS.  There are very limited choices.

I hope that helps.  Let us know how things go.
Good luck,
-Shawn

Thanks for the reply well yes it has been sitting in storage and friend was going to throw it away and I got it instead...

Well, the power supply its a slide in unit on the back says:

100-240 v 50/60hz 1.5a  and it just slides into the back with a power cord connection ..

I will check the files section....

I open it up and there is a floppy and a hard drive unit install...

I will try what you suggested first let you know how it went..

Miguel,
I think you have the correct power supply.
Here is something to try:
Open the 1550 back up, and remove the hard and floppy disks.  Then, remove the hard drive and only install the floppy drive. Re-assemble everything (you can leave the top cover off).
Then, try to boot it up and see what happens.  If you have a bootable floppy disk, put that in the disk drive, apply power and then see if the 1550 boots up.
Try that and let me know how it goes.
Thanks,
-Shawn

ok, I went ahead an open the top cover and disconnected the hard drive cable... then I turn the switch on and the 3 green lights came up quickly on the front and after that nothing else happened??  then I plug the hard drive again and disconnected the floopy drive and again 3 green lights came up and nothing on the screen..

then I took the modem off then I heard a short beep and I can see the disk green light on but nothing on the screen..

I think now something else went bad or a controller inside is bad..

or could be that the video screen went dead since it was flickering on and off...

oh well... now i get why he wanted to throw away  ....

Nice try,, but I am open to try anything else

thanks for all the help...  maybe its something simple...

Shawn,  is there not an option in the bios or something on them to have 
it boot into the built in screen or external screen but not both?

If there is that could be why the internal screen displays nothing, 
Miguel you might want to hook an external monitor to it and see what 
happens.

Hi, Len.C, Ac4mo

The option to switch to an external screen is CTRL-ALT-TAB, but the computer has to be booted up to do that. It's not part of the BIOS. It's a built in DOS command.

To ac4mo.........At this point, I doubt there is much you can do. If you can put the computer back to its original state, then you can get back to the HARD DISK FAILURE position. Unfortunately, as Shawn had noted, the problem is most likley going to be that the hard disk has indeed died, and your only option is to replace it. I don't believe the 1550SX was designed to operate without a hard drive in it. I could be wrong, but the technology was so primitive in those days that any small hardware deviance could spell disaster because it almost all had to be individually coded into the boot up BIOS program.

However, replacing that old hard drive is most likely not going to be possible as it is a very old technology that no longer is used and probably no longer available. YOu mihgt be abel to go to an old computer salvage store where they have these things and luck out. But I doubt you will be able to find a replacement. The computer may be good for parts to someone else who may have an otherwise functioning 1550SX. I have one functioning 1550SX, and two dead ones. They may only be motherboard failures and their hard drives may still be good, but I also can't get to them as they are in semi-permanent storage until I can buy a new house, which may be quite a while, unfortunately, thanks to the market forces at work presently. It's also likely the CMOS battery will have to be replaced as well. So it's going to require a fair amount of work to be able to salvage this unit.

I wish I had better news for you. Good luck.

Phil

Hello, Phil

that is what I figure out too, because at the begining the screen was flickering on and off and then stays on then off again, something was causing it ...

I saw the CMOS Battery that can be replace but there is no guarantee that would make the system run again... so I am going to try and salvage as much parts I saw it has a modem card has a us robotics logo on it and other things that can still be working...

and maybe someone needs parts and just sell the whole thing for parts...

Thanks Phil, shawn and everyone else for their help I appreciate very much...

Miguel

Ok, I took practically the whole thing apart,,  the hard drive can be replace the only downside is that the power connection is a small connector instead of the regular one... but after that put everything back together again..

then when I turn it on, whao even the screen worked... but I get the BIOS message and after that all I get is a -  and blinking

then it gets stuck there... so I think something inside was loose and now it works..

But maybe there is a an adpater por the power connector because when I took the hard drive it looks like a regular IDE hardrive same things except the white connector small for the hard drive to power up....

Maybe if I find a adapater and I power with a big connector to convert to small...

But at least I got something on the screen

Miguel,
I don't understand something.  Did you remove the hard drive or did you preplace it with another hard drive?
If you replaced it with another hard drive, I'm 99% sure the Grid will not boot from it.  The hard drive has to be 1 of 6 specific Conner hard drives.  This cannot be changed.  The hard drive model numbers are hard coded in the BIOS.

Hello, Shawn

I did remove everything and plug everything back the way it was..  I saw the conner hard drive and I inspected and everything seems to be ok and I just hook it right back up... I mentioned that I compared to another hard drive and that they look the same but you explain now that it has to be specific model for the grid..

Now what I am getting is this

I turn on the switch and it starts but nothing happens you can hear the fan turn on, I turn it off then it starts but right after the 640k memory test it looks like it powers down and I have to turn the swtich off...

then another try I get 3 short beep stop and 2 beep the same

Also I notice that the CMOS battery was clip off on one side so I put a battery tester and its showing good so I re-attach the CMOS battery .

I think what I need is the start up disk for this machine, maybe my bios settings went to default and that is why its not booting, it tries but dies down..

Miguel

Subject: Re: Still alive the gridcase 1550SX

Hi Miguel,

If I understand you correctly, you were able to get the BIOS to activate and got a BIOS message but then it got stuck. This tells me three things. One, your motherboard is working. Two, your BIOS is working. Three, your hard drive has failed as the computer BIOS has now turned over control to the OS, which is located on the hard drive, but it failed because the hard drive is now bad, so the computer freezes up.

Therefore, you have a workable computer except that the hard drive is gone. You MIGHT be able to get it to boot from the floppy instead. You have to press "F" during the BIOS initiation phase to get the computer to try the floppy instead of the HD. That is the command for the 1530's to do the same, and I don't think it's changed for the 1550's.

If that doesn't work it may be because the BIOS is confused and has hung up. If it doesn't see the hard drive, it may not load up any more devices afterwards in its instructions, and if this includes the floppy, then you won't be able to boot up since it won't see the floppy either.

As to the hard drive, your only option is to replace it. Shawn is right about which HD's you can use. This was the mid 1980's to late 1980's. DOS was actually relatively new, and very primitive. IDE as a protocol for HD"s was just making its way onto the market. BIOS's were primitive and had no actual program you could bring up to control them. The company simply hard wired the BIOS onto the BIOS chips, and that was it. The user had no control over it. It was not required back then for users to do any of that.

Since there was no standardization protocol for connecting hard drives at the time, each computer BIOS had to hard wire the parameters of the hard drives into the BIOS in order for the DOS to recognize it and allow the computer to see it. In GRiD's case, they hard coded six hard drive types into the BIOS. These were a brand called Conner hard drives. This was a company that was active at the time, but later got bought out by SeaGate in the 1990's.

So, in order to replace the HD in this computer, you would have to replace it with one of those six specific HD's burned into its BIOS. We actually have that list of accpetable hard drives here on the site. The problem is, finding any of those old Conner HD's is next to impossible these days.

Shanw and I have managed an alternative solution however. The BIOS on the computer is located in two removable BIOS chips, each of them 128K ROM chips. We have both taken these chips out and put them into an EPROM burning device (attachable hardware to a computer) and used the software associated with it to extract the the BIOS code into a simple HEX file. Taking other old Conner hard drives not originally intended for these computers, we altered the code in the BIOS in the tables meant to document the HD data such that the parameters of these other hard drives were listed on the tables. (The credit is Shawn's. He actually worked out the protocol.) We burned new EPROMS with the altered BIOS code and put them into the machines. For example, we each took an old Conner CFS420A hard drive and managed to fit it into our computers (his is a 1520, I did it on my old 1530). So it is possible to use another hard drive of that era and make it usable in these old computers. It shouldn't really be any different on the 1550SX, I think. However, we don't know if we can use an old hard drive from another manufacturer. Theoretically, it is possible, but none of us have tried that yet.

The possible candidates for this are the older Conner HD's of less than 500 MB size in general, and which have the same pin configuration and positioning as the backboard in the computer. When you look at it you will see it is different from today's IDE pin placement. The complication is that you would have to procure some EPROM burning equipment to use, and then take the original BIOS chips out of the computer (not much of a problem there. They are removable.) and replicate the process we used, taking the original 1550SX BIOS code and altering it for a new hard drive, if you find one. You would burn the new EPROM chips and put them in the computer, install the new hard drive, and then you should be set. You would, of course, then have to reload a new OS onto the hard drive as if it were completely brand new. Even then you have to be careful as even the various DOS OS's might give you problems. After that, you could load the earliest windows, like version 3.1.

Anyway, that seems to me what you are looking at for now. Good luck.

Phil

Hi Miguel,

Okay, first, the CMOS battery will test good because there is no load on it. Don't believe it. That battery has been in there for over twenty years. Trust me, it is bad now. It will need replacing.

Two, the beeps code, I would have to look up, but it sounds like there is now a memory problem. One of the memeory sticks may not be seated well or have gone bad. Make sure they are well seated and that none of the pins have broken off. I believe it is a memory problem because the BIOS would shut the machine down in that case, if I am not mistaken. There is a table of beep codes in the manuals, but I've forgotten exactly where it is. It should be the same for all the 1500 series computers.

When you turn the machine on, you MUST hear one single beep and one beep only, which tells you that the POST (power on self test) has successfully completed and tells you the MoBO and mameory had passed start up inspection. Don't even worry about trying to boot from the floppy until you get that problem fixed.

Good luck,

Phil

Hello, Phil

thanks for the reply,,,

well, I gave it a good try and I even got the screen working again, but I think its time to end this proyect,, because even if I find another hard drive and possible hex the bios chip there is no guarantee and right now cash is not good if I had it then I will go for it but its not possible...

Thanks to shawn and to you phil for the assistance...

Subject: Parting out my old GRiDCase 1520

Hello,

I am parting out my GRiDcase 1520. I'd also be willing to sell the whole thing. The hard disk drive functions well, few bad sectors, recently formatted. I can send the contents that were on the hdd when I received it if wanted, it is 40mb. The floppy disk drive functions, everything functions well.
Faults:
1. The mainboard needs a new dallas rtc chip, I have already made (albeit rather large and messy) holes in the top of the chip for leads for an external battery.
2. The right hinge is broken, and missing somewhere away from the other parts.
3. The alt key on the keyboard does not currently function. Some of the other keys need extra force applied when depressed occasionally.
4. The main battery holds a charge of maybe 30 minutes at best right now, it needs to be cycled and possibly a high voltage shock to get the crystals off the cells.
The unit is rather clean. If no one wants it I'll ask the members over at vintage-computer.com. If all else fails it will just remain where it is, so no need to worry about it being trashed.

Thanks

Which model of hard drive does it contain?  I assume it is a Conner.

Hello,

It is a Conner CP-3044. The drive will be formatted, primarily so others will not see my horrible config.sys and autoexec.bat settings, never quite recovered from the Windows transition... It may be of importance to know that any parts from the 1520 would be shipped out from PA 19525.

Judging from what you said, I could actually repair this unit, except for one thing, maybe. I have several dead ones I use for spare parts, and so I have an extra hinge and extra keyboard I could put into it. However, the Dallas RTC chip will be a big problem. ON the 1530's you can replace the RTC with the 12880 that is still available, but this doesn't work on the 1520's. The BIOS is still too primitive and if you try to replace the chip it wil lock the boot up into an irreversible mode of asking for a password BIOS, for which of course, there isn't one, and you can't ever boot it up. So unless you can repair the old one already there, the MoBo is shot as far as that particular problem is concerned. However, I could possibly do it. How much are you asking for the entire unit?
