  hello
  thanks for replying... I bought it on ebay  but the person that i bought 
it from was  not totally honest.. left out some things...  ram being one of 
the things......  I think it's stick ram   goes under that little plastic 
piece  under the screen.....  the machine will turn on  but it won't 
boot  i'm thinking  that it wont boot because of the ram thing  and no OS...
  thanks man...

Too bad you  didn't know what kind of ram it takes?  Dips? 256k strips?
simms?  Maybe even a separate board that plugs into a slot?

Simms are sticks but we still have no idea what you are looking for or
how many, if it comes with 1 meg is that 1, 1 meg chip or 4 256k chips,
is there more than 1 slot on this or what?

Maybe time to dig out the old radioscap catalogs and look it up or even
to the website and see what it says.

It's been awhile, but as I remember, the Tandy 2810HD,
Grid 1720 and Panasonic CF270 were all basically the
same thing. They all used the same Panasonic board. I
still have a CF270 that I play with on occasion.If you
can wait a few days, I can take it apart and see if
there is a part number on the ram. I upgraded my unit
to a whopping 60MB Conner hard drive. By loading DOS
"high", I am able to run Windows 3.1 and Word 2.0 with
no problem- other than being rather slow. 
You may want to check the eBAY seller on the link
listed previously- unit didn't sell so may make you a
deal or relist it for you.

Yes it is over but it does not mean he sold the item, it says it was not

Gig,
If you reach the point of taking the 2810HD apart, the
"magic" screw that nobody ever finds is under the
power/charging LED. There is a small plastic rivet
that holds the small board in. Pry that out and the
final screw is underneath the board! Enjoy!

Hey,
  thanks  we have had it apart before... and found the screw!  thanks.. 
well we were able to get the top off  so i'm guessing  that we found 
it......  But i don't think that we need to do that any further  i just 
need ram and an OS  which i have  -but not the ram  but since my old LT is 
working  i'm not that worried about it anymore  but it's nice to have  a B/U..
  thanks for all of the help...

Subject: Re: [RuGRiD-Laptop] Gridcase 1535 EXP and PC slot history

 I've just received the SCSI module with documentation
I bought on e-bay. As I expected it does a BIOS overlay 
on the Grid BIOS just like a SCSI or Video board does
on most computers. I imagine the VGA module does the
same thing. The SCSI module has selectable jumpers for 
four different ROM-BIOS base addresses, IRQ 3 or IRQ 5
as well as 2 time-out delays.
The Controller is a Future Domain TMC900 Gate Array.

"The base address determines where in the PC's ROM
Scan Space the SCSI Controller BIOS will reside"
(CA00:0000 to CA00:1FFF, C800:0000 to C800:1FFF
 CE00:0000 to CE00:1FFF, DE00:0000 to DE00:1FFF)

 I'm not much of a hacker but that would seem to imply
that these areas are available for some BIOS code of
devices on the GRID and would have to be accessed
at power-up. Perhaps a controller in the module slot,
the least inelegant of solutions.

 The module has software to configure the SCSI device
from Future Domain called "Disk Maestro" which is
used at start-up.

 I still haven't obtained or installed a Dallas chip so
It'll be a while yet before I can try out the module
with my Syquest drive. I notice that the software
does have a program for partitioning and formatting
removeable drives (as well as Tape drives and 
optical disks), so that's encouraging. 

 Hopefully someone more knowlegeable might be
able to use the above info to address the problems
with the Grid's HD size and OConnor models.

I added this private exchange so that this would 
be comprehensible.

Hey Lawrence!

Everything sounds like it would work, but I'm not sure
how On Track would fool the BIOS.  I imagine the BIOS
EPROM is read into RAM on power up.  If the drive
types don't match, then it won't boot.  Since On Track
is a program that would have to be executed, how can
it load before the BIOS is program is run?
I must be wrong or else On Track would have never
worked.

I'm still plugging (slowly) away on the project.  I'll
keep you (and the list) posted on my progress.
Good luck on the SCSI interface.

HHmmm...It sounds like you're saying the motherboard
BIOS is interuppted and prevented from loading so that
a version of BIOS on the SCSI card is loaded instead.
Neat approach.

I don't know if they can use the other 15XX series drives, but I do know  
that they came equiped with different ones than the others.  The 152X-153X  hard 
drives had a problem with the read/write heads sticking to the disk and the  
1550 fixed that problem.  But I'm not sure if the old ones will work  too.

  The finishing rim around the keyboard is removable.
  it's a snap-on.  If you pull up on it between the
  display hinges it will sort of peel off.

  You will find the RAM sticks between the uper edge of
  the keyboard and the floppy/HD brackets.

  Between the floppy and the ram sticks there should be
  a lithium battery (one of those round pink ones)

  If there is no lithium battery installed you likely
  have a Dallas chip that has the battery imbeded.

Len,
Just so we are on the same page, "above" the keyboard,
there is the RAM, correct?  Still moving "up" the
motherboard, there should be purple/pink battery. 
Specifically, mine is a 1/2 AA made by Tadiran. 
Also,there is a sticker on my 1520 motherboard that
says "Revision AE."
Do you have an different revision level board?
Thanks,

  It's likely that this has a Dallas chip battery as Charles says.
  It can be found under the keyboard and unfortunately has to
be unsoldered to replace the still available, from Dallas, chip. 
Anyone know another, retail, source ?

The old Dallas part number is obsolete, it has been replaced with a y2K
compatable clock.  I do not know the new number.   

Look in the group message arcive around jan-mar 2000

If I remember correctly sombody found the new part shortly after the Y2K
crossing.

The finishing rim around the keyboard is removable. 
it's a snap-on.  If you pull up on it between the
display hinges it will sort of peel off. 

You will find the RAM sticks between the uper edge of
the keyboard and the floppy/HD brackets.

Hello,
I haven't had the time to use my GRiD computers for quite a while, my
three kids are all playing hockey, so I have reluctantly decided to
sell them (the computers not the kids).  One of them works, the other
has a bad hard drive.  I bought a replacement drive for it but the
connector wasn't identical.  The computer has sat on my desk
unassembled waiting for me to modify the connector.  Take a look at
the auction if you are interested.

Hello All,
I picked up the Grid with no documentation.  The device boots up and lets me choose an OS (either MS-DOS 2.11 with BIOS Version C or Version 134.1.4 GRiD-OS / Version 31.0.0 of Common Code).  

If I boot into MS-DOS, I get an A: prompt.  If I do a "dir" command, it brings up 3 files but that's it. 

If I boot into the GRiD-OS, I can get to some menus, but then it needs a password to continue.  Does anyone know a hack to bypass the password?  Or does anyone have access to the GRiD-OS software so I can reinstall?

I would like to get this thing working but it is very difficult to find any information.  Any ideas?

Thanks,

Jeff

This works on most mainboards, for CMOS passwords:

Kill all power and remove the battery. Using normal anti-static
procedures, pop the case and locate the CMOS 'default' jumper... three
pins, with a jumper on two. If there is more than one likely suspect,
try this on all of them, it will have no effect on other jumpers.

Just slip the jumper off its 1-2 position, and set it to the 2'3
position, then wait a second or two, and put it back the way you found
it.

This will reset ALL CMOS setting to factory default, and wipe out any
CMOS password, in the process.

 While this is true for many CMOS settings, on the Grid 1520/30 at least,
it is not so for the models with the Dallas batteries. They require you to
short 2 pins in order to reset the CMOS which is contained in the Dallas
chip memory. IIRC I placed the pin settings in the file section some time back.
I don't know whether the Compass ll uses the Dallas chip tho.

1989...

The original target market was Military communications e.g RATT
INET/Telix and other teletype applications as a replacement for the
UGC-74 digital teletypewriter.  This unit was demoed at 3-core "Ft Hood"
in the summer of 1983 (I was there) after the UGC-74 proved to be to
brittle for field use. (I was there too.  Brittle is the polite word) The
fact that it runs DOS is merly the GRiD superiority to other millspec
providers of that era, and added an attractave vercitility to the device.

This works on most mainboards, for CMOS passwords:

Kill all power and remove the battery. Using normal anti-static
procedures, pop the case and locate the CMOS 'default' jumper... three
pins, with a jumper on two. If there is more than one likely suspect,
try this on all of them, it will have no effect on other jumpers.

Just slip the jumper off its 1-2 position, and set it to the 2'3
position, then wait a second or two, and put it back the way you found
it.

This will reset ALL CMOS setting to factory default, and wipe out any
CMOS password, in the process.

All,

Unfortunately I didn't buy the laptop from an individual.  It was in an abandoned house and I picked it up when they gave everything in the house (furniture and all) away for free.  Fortunately for me, I also picked up some other rare computers.  This means I have to way to get the password.  I believe my only hope is to get a copy of the manual or a copy of the software and try and reinstall.

Does anyone have a source where I can get a floppy drive for this machine?  It has a 19 pin serial connector on the back.

Thanks,

Jeff

The floppy drives for the early GRiD Compasses are large (about the size of  
the laptop itself), use 5.25" disks, and are connected to the GPIB outlet  on 
the back.  I have one for my Compass 1101.  I don't know if the guy  I bought 
it from still has anymore for sale, but if I can find his e-mail  address, 
I'll send it to you if you want.  However, the big problem is  trying to find the 
software to install into the machine (especially GRiD-OS and  it's programs). 
 If you find any older manuals for the GRiD's, let me  know.  I myself am 
searching for different manuals too.   Hopefully you'll find a way to get onto 
the GRiD.

Oh yes...

Using the original BIOS ROM you will need one of the following
Conner CP3022,CP3024,CP3044,CP3042,CP3104

The 1530 is model number sinsitave.  We have a program for you if you
have access to EPROM programing equipment. 

Download http://groups.yahoo.com/group/RuGRiD-laptop/files/1530ROM.zip

You will find the file "1530ROM.EXE". Go to a dos prompt and execute that
file.  You get a screen full of hex code with questions at the bottom.
e.g number of cylenders and so fourth.

When this program is compleated it will generate even and odd bin files
for your 1530 in a subdirectory named for your drive model.

This is limited to 16 heads 1024 1024 cylenders and so fourth.

Also there are several of us who would like to use compact flash for that
application.  What is needed is an ATA-boot patch for the 1520 & 1530
roms

This will also allow you to use any drive

What programming languages can be run on one of the old GRiDCase

processor, 640k total RAM, 720k floppy, MS-DOS 2.11, monochrome

not that expireinced with programming and I need something that's for 
the most part easy to learn.   

I am currently trying to make a sentry gun terminal program like the

QuickBASIC 4.5, but I need to be able to change the font size and if 
possible type.  I can't seem to figure out how to do that with 
QuickBASIC.  I also need to be able to highlight the text in SCREEN

What programing language would you like to run?

Anything that runs at an MSDOS prompt and is NOT 3+86 exclusive will run
on this unit.  Plus Graphical applications that are compatable with the
video mode.  Some 1520s have VGA.

You should be able to write your program using the quickbasic provided
with MSDOS 5 and above.  Also I think I remember about 2 years back
someone else was trying to do this and had some work done on it.

Usually any time I have a problem with a floppy it`s dust ...I even check 
under the silver hatch on the old disks to see if there`s a spec on the disk 
itself ..sometimes the same fleck will slide around on and off the heads making 
the disk work on and off.

Chris, It was dust! I inserted the nozzle of my newly aquired mini vacuum; gift 
from significant other, in the floppy drive & cleaned for a minute or so. After 
this I inserted a disk and everything worked like a charm.  Thanks for the tip.

Unfortunately, no.  I now have to get a new scanner, since my current 
one is too old and I'm not sure if I'll be able to get one anytime 
soon.  I'm trying to see if I can use somebody else's scanner until 
then.  Once I get them scanned and turned into a .pdf file, I'll put 
them in the files section.  

By the way, I found out about this program called PDF 995.  It 
supposed to make creating pdf documents easier.  The webpage is here 
at http://www.pdf995.com/.  This might make putting those manuals on 
here a lot easier.  

Also, I remember seeing there was a site posted on Rob's GRiDBoard 
that had the Compass 1101 for download and a lot of useful 
information.  The site is up anymore, but I e-mailed the guy that ran 
it and he said he didn't have a copy.  Maybe somebody still has a 
copy of it.

Marty,
There are at least 3 ways:
1. The instructions are at the bottom of each email.

-or-
2. You (as well as any list member) can go to
groups.yahoo.com.  Click on the Rugrid-laptop group,
and on the right side of the page, click, "Leave

-or-
3.  If all else fails, say the word and a moderator

Subject: 1520 in need of a floppy

Hi group!

I'm a new owner of a very clean 1520 which boots, to a point, and seems to 
work fine except that hard drive error 02 comes up after the memory count. 
I'm in Toronto and  my question is, does anyone have a spare 1520 external 
floppy drive to offer me or even lend me to get the 1520 up and running.

I'm figuring that the hard drive, it's 100 megs, has been wiped and needs to 
be reformatted and loaded with a new os. It would also be interesting to see 
what was on the drive, too! Since the drive is the 100 meg version, there's 
no floppy except for the external one.  Initially I would try an undelete 
program and then load a basic DOS version.

Thanks for any help or tips anyone can offer.

Subject: Re: [RuGRiD-Laptop] 1520 in need of a floppy

Hey Brian,
I think somebody may have added that drive to the
computer in an attempt to get a larger hard drive. 
The problem is, the BIOS in the Grid only recognizes 3
models: the CP3022, CP344 and the CP3104.  They were
made by Conner Peripherials (or however you spell
it!). I believe the CP3022 and 344 are 20 MB and the
3104 is a 40 MB.
If you add any other drive that isn't in the BIOS,
then the computer won't boot (as you already see).
Back in the 80's when it was designed, BIOS wasn't
like it is now where you hit a key and that allows you
to go in and change things.  BIOS was hard coded and
couldn't be changed.
You may be able to find an old drive on Ebay or
somewhere else.  The problem is the bearings are so
old, the oil leaks out and they end up seizing or not
being able to spin up to speed.

I was going to see about getting my 1520's to boot
from compact flash.  It's a good idea but I've lost
the motiviation to do it.  Let's assume I got it to
work.  What am I going to do with a 286 machine?  I
can't even run Linux on it.

So, back to your original request for a floppy.  Yes,
I have one I can send to you.  I'll send it to you for
the price of postage.  Email me privately if you're
interested.
Also, there was another person on the list who asked
if I had a drive.  I'm sorry, but I deleted your
email.  I have a drive for you as well.  Email me
again if you're still interested.
Good luck,
-Shawn

Subject: Re: [RuGRiD-Laptop] 1520 in need of a floppy

Hi Shawn,
I was reading the posts from the very start and it seems there was a model 
with the 100 meg drive and this resulted in the floppy becoming external. 
That's what I gathered anyway. The drive spins up, but if there was nothing 
on it, this may create the 02 error. That part is just supposition on my 
part.
Yeah, I know it's a 286 but I'm trying to get it running just because it 
might. I collect computers, and this is the neatest laptop I own. I have a 
Panasonic with a similar screen but it's just not as cool as this. I have 
various DOS versions I could put on it, but mainly I want to access the hard 
drive somehow to see if it is intact and I can only do that with a floppy.
So it's an external drive you have? Is it a standard cable or do I need a 
special one?
If you let me know how much postage would be on it, and where you are, I 
will send down a money order. If you're in Canada, even better but I have 
stuff mailed up all the time from the States. Just normal parcel post works 
best since there is no duty etc. on it.
Thanks Shawn! I appreciate the offer.

Brian

Subject: Re: [RuGRiD-Laptop] 1520 in need of a floppy

Hey Brian,
Yeah, I kind of remember some posts about that too,
but I wonder...
OK, I just Googled "CP3104" and found that it was a
100 MB drive.  Seagate bought out Conner Periphials
and the link to the drive is here:
http://www.seagate.com/support/disc/ata/cp3104.html
 So, it looks like my previous post is in error. 
Well, it's not the first time. ;)
 
So what are you options?  It looks to be a standard
IDE drive.  If the drive is still good and you're
interested in the data on the drive, you could removed
the drive from the computer, and pop it in any post
386 computer.  You should be able to see the data on
the drive.
One more thing, if the drive was "empty", I would
think you're get an "Missing Operating System" and not
the Harddrive Error 02.

My guess is the 100 MB drive is taller than the
traditional 20 or 40 MB versions and that's why there
is no floppy.

BTW, the floppies I have are internal drives.  And,
I'm in the lower 48.

And something else just occured to me:  the 1520's
with the 20 and 40 MB HD's have the floppy drives
above the hard drive.  There is a special IDE adapter
board that connects the drives to the motherboard.
Your IDE adapter board *may* be different and not have
a provision for a floppy since the 100 MB models don't
have the space for a floppy drive.

I have never had a 100 MB unit so I do not know. 
Perhaps another person on the list knows more (Len?
Charles?),

Perhaps you could find one there.

Thanks Shawn. I will attempt to get the drive out to see if there is 
anything on it. Thanks for the lead on the external drive. The payment 
arrangements are a bit screwy though. Maybe I can put an os on the drive in 
another computer and then reinstall it on the 1520.

I came across some sites with Grid files, there's some at AST and some at 
RadioShack in the UK. Are these new to the group? Should I link them or post 
them? There are quite a few and many more than are in the groups file 
section but I know there are space limitations for the group. Still trying 
to find an online manual. I'm sure they are somewhere, just haven't had the 
luck yet.

No, not new.  IIRC, these have to do with Grids made
after the sale of DGrid to Tandy and then to AST.  I
believe the 15XX seriers was ade prior to the sale.
Perhaps we should have a link.  There is a Files
section to this board.  Perhaps you can put it there.

Let me know how you make out with your project and if
you still want the my floppy.

I have an external floppy for the Compass 1101 and it uses a GPIB

Subject: GRiDCase 1530 Refurb (HD and CMOS)

Hi all,

New to the group.  I've had a 1530 (VGA) now for over 14 years. 
Bought it in the Navy and it has been a tank ever since...well, ever
since I loaned it out.  Got it back with a HD failure I assume.  The
system hangs after the Memory Check and when it does get past it
(rarely, the C Drive doesn't boot)  Did boot once after a LONG time on
the floppy (Int 3.5).   I have a 40MB HD in there and may need a new one.

1. I suspect the CMOS is dead too.  Would that prevent the boot from
the HD?  If so, can someone point out where the CMOS battery is
located inside.  I tried to get under the keyboard and it seems fairly
solid there.  Would hate to break something.

2. Can someone point out a source to purchase a new HD?  If I get the
same HD (or fix the old one), will I need to burn a new EPROM?  Read
some stuff here about that and I don't own a burner.

3. Need a couple batteries refurbed as well.

Plan to use the system in the field some (flight test) and would love
to get her back in shape.  Any help would be appreciated.

Andy,
I don't know what hex editor you're using.  I use(d) a
program called Winhex and you can get it a
www.winhex.com.
The 1520 BIOS is stored in odd and even EPROMs.  Using
an external EPROM reader/burner, I copied the contents
of the EPROMS to disk then used Winhex to merge the
two files together.
Then, I searched through the merged file for the
character string "CP."  I used "CP" because the three
Conner Peripherial drives that work with the 1520 all
start with CP (CP322, CP344 and CP3104).  As luck
would have it, all three drive models were located
together.
I'm not familiar with the 1755.  Perhaps you can do
the same process I did.
Good luck,
-Shawn

CMOS look as it described in some documents, but in that areas,where

I don't mean to sound like a smarta**, but in a DOS

located in and type 1530rom.

> Can it  be run  and used to allow different

Yes, follow the prompts and it will create new values
that have to be pasted into your ROM files.

>Does this program need to be burned into an eprom ?
 
Not the program, the values that the program generates
get into the file.

Here's how it appears to work:
1.  Remove the BIOS EPROMs from the 1530.  I believe
the 1530 has an odd and even EPROM.
2.  Using a EPROM reader/burner, copy the contents
from the chips and save them.
3.  Using a hex editor, merge the two files together
and save the merged file.
4.  On a separate computer, run 1530ROM.exe.  Enter
the values for your new drive that it asks for.
5.  If the vaules are valid, the program will show you
the corrected enteries so that new drive will work
with a 1530.
6.  Using the hex editor, change the values in the
address locations that the 1530rom.exe shows.
7.  Save the new file.
8.  Use the hex editor to split the file.
9.  Use the EPROM burner to burn the new data into the
EPROM's.
10.  Replace the chips into the GRID.


You may need spare EPROM chips.  You can use the same
ones that you removed, provided that you have a UV
light to erase them.
Good luck,
-Shawn

Close...

Run the program.

There is a copy of the 1530 ROM in the ZIP that the program looks at for
referance.  After you add your HD values to the table it will create two
new ROM images in a subdirectory named for the model number of the drive.


Use the even and odd files in that subdirectory to burn a fresh set of
ROMs and replace your original with the new ones.

The limits are unfortunately locked to 1024 cylenders 16 heads and 63
sectors.  This come out to 504MB.  Any larger drives will have to use
these parameters to boot and a DDO (Dynamic Drive Overlay) to access the
larger size.

No problem (its been a while)

So, if I understand you correctly, the original file

 - Correct it should already be in the zip file.

Is there a particular filename or format it's looking
for?  
 - EVEN.BIN and ODD.BIN should be already provided in the ZIP file are
binary ROM image files (size 16734 bytes.)

Am I correct in assuming it needs the merged file?
 - No...  The EXE creates new set of fully ready image files just burn
thim into a 27C128 and go.  The new files will be found in a subdirectory
that the program names using the drive model number (Automatically
orginized) The program also automatically adjusts the text in the
copyright statement to match the checksum.

They are EVENWORK.BIN and ODDWORK.BIN

I have used this program several times and have 400MB or larger in all
three of my 1530s.  Plus I have tried this program on a compact flash
using an adapter.  It seems the ATA table in a CF is slightly different
and the GRiD will not recognise it. (next problem to fix...  an ATA
autosence and boot for the 1530)

ROM file has to be in the same directory, right?
- Correct it should already be in the zip file.

Is there a particular filename or format it's looking
for?  
- EVEN.BIN and ODD.BIN should be already provided in the ZIP file are
binary ROM image files (size 16734 bytes.)

Am I correct in assuming it needs the merged file?
- No...  The EXE creates new set of fully ready image files just burn
thim into a 27C128 and go.  The new files will be found in a
subdirectory
that the program names using the drive model number (Automatically
orginized) The program also automatically adjusts the text in the
copyright statement to match the checksum.

They are EVENWORK.BIN and ODDWORK.BIN

I have used this program several times and have 400MB or larger in all
three of my 1530s.  Plus I have tried this program on a compact flash
using an adapter.  It seems the ATA table in a CF is slightly different
and the GRiD will not recognise it. (next problem to fix...  an ATA
autosence and boot for the 1530)

Any help we can offer?

Also... If you are aware of the method DOS uses to set the device
controls we could use a brief.  Several of us are trying to modify the
GRiD 1520 / 1530 to accept and boot from any hard drive via ATA table
auto setup.  The end goal (in my case) is to be able to use a compact
flash for a harddrive.

The open and detailed discussion about 1530ROM.EXE answered all the questions I had.
I'm using the 1530 drive info you posted earlier to purchase a compatable used drive .
This will get the GRID up and running quicker. My source for drives is  (sunstarco.com).
Your 1530.EXE is a great tool .I intend to use it in the future. Thanks for sharing it !

  Close...

  Run the program.

  There is a copy of the 1530 ROM in the ZIP that the program looks at for
  referance.  After you add your HD values to the table it will create two
  new ROM images in a subdirectory named for the model number of the drive.


  Use the even and odd files in that subdirectory to burn a fresh set of
  ROMs and replace your original with the new ones.

  The limits are unfortunately locked to 1024 cylenders 16 heads and 63
  sectors.  This come out to 504MB.  Any larger drives will have to use
  these parameters to boot and a DDO (Dynamic Drive Overlay) to access the
  larger size.

  Sheldon,

  I don't mean to sound like a smarta**, but in a DOS
  window, change to the directory that the program is
  located in and type 1530rom.

  > Can it  be run  and used to allow different

  Yes, follow the prompts and it will create new values
  that have to be pasted into your ROM files.

  >Does this program need to be burned into an eprom ?

  Not the program, the values that the program generates
  get into the file.

  Here's how it appears to work:
  1.  Remove the BIOS EPROMs from the 1530.  I believe
  the 1530 has an odd and even EPROM.
  2.  Using a EPROM reader/burner, copy the contents
  from the chips and save them.
  3.  Using a hex editor, merge the two files together
  and save the merged file.
  4.  On a separate computer, run 1530ROM.exe.  Enter
  the values for your new drive that it asks for.
  5.  If the vaules are valid, the program will show you
  the corrected enteries so that new drive will work
  with a 1530.
  6.  Using the hex editor, change the values in the
  address locations that the 1530rom.exe shows.
  7.  Save the new file.
  8.  Use the hex editor to split the file.
  9.  Use the EPROM burner to burn the new data into the
  EPROM's.
  10.  Replace the chips into the GRID.


  You may need spare EPROM chips.  You can use the same
  ones that you removed, provided that you have a UV
  light to erase them.
  Good luck,
  -Shawn

Hi All;
Just joined this group and am happy to see that it is a very active group.
I just aquired a Grid 1520 last week for $5 at a local thrift store. 
I took it home and connected a power suppy and was surprized how well
it runs.  It's of course a 286 running Dos and Windows 3.1.

I'm not real sure what I want to do with it.  One option is to use it
as a computer for amateur radio packet.  My other thought was to gut
it and put in a mini ITX motherboard (1Ghz), 80Gig HD and replace the
monitor with a touchscreen 7" Colour VGA.  Then I could use it as a
Laptop and for GPS in the vehicle as well as for CNC.  Has anyone done
this with their Grid?  The case construction is amazing.

Guting the machiene we consider to be blasphemy on this list.  Besides
you would be better off building a custom case around your ITX as you
will likely have problems fiting heatsinks and power supplys.

Which program are you using for packet?  Are there any freeware dos

I'll dust off my old PK232 MBX and connect to it.

It is amazing at how well it's working.  The speed is not to bad.

Luckily, I happen to be a big Aliens fan.  The ones used in the movie 
are the early GRiDCase series.  It's believed to be a Case 2 or Case 
3 (it may or may not have been Tempested).  They also happened to 
have yellow plasma screens.  They also had the their ROM sockets 
located on the left side, under a removable panel (some GRiDCases had 
them strait across).  That's about all that I know about the laptops 
in the movie.  

The others on this list know more about GRiD's than I do, so they 
might be able to tell you more.

As for the sentry gun control terminal program...well the information 
is scarce, but if you want I can tell you what I know, but that's 
pretty much not really anything.  There are also a few replicas of it 
though.

For more info, you might want to check put these sites,

http://pub217.ezboard.com/bthealienslegacy

http://web.archive.org/web/20030715091935/pub11.ezboard.com/faliensarc
hivefrm11

The first one is to an all aliens discussion forum.  This is a great 
board and they would be happy to answer any questions.  They have 
several previous discussions about the GRiD's in Aliens in the 
archives.  You might want to check there first, before you post 
anything.  I also happen to be a member of the board (my name is VT 
1010).  

The second link is for an archived version of the first Aliens board 
(we switched to a new one last year).  There was a whole section 
deticated to the GRiD's so there might be some more information there.
It's an archive however, so you won't be able to post any new 
messages or anything.

Does anybody know anything about programming in GRiD-OS or InteGRiD 
(like what language do you use, etc.).  Thanks.

I'm not sure I understand what you mean.  Isn't
GRiD-OS a derivitive of MS-DOS.  So, wouldn't just
about any language that can compile a program to run
on a 286/386 DOS run under GRiD-OS?
I don't know anything about InteGRiD.  Is it a crude
GUI like Tandy's Deskmate?

No, actually GRiD-OS is a completely different OS from MS-DOS.  You 
must be thinking of GRiD MS-DOS, which is pretty much the same as 
standard MS-DOS.  GRiD-OS is a menu based OS that was designed for 
the GRiD Compass.  InteGRiD is an emulator for DOS that runs GRiD-OS 
programs and has the exact same appearance as GRiD-OS (InteGRiD is 
available for download in the files section).  GRiD-OS was on the 
Compass and early Case series.  Since GRiD-OS isn't that common and 
only available on early GRiD laptops, there isn't alot known about 
it.  

Does anybody happen to know how to write programs that will work in 
GRiD-OS and InteGRiD?

text/plain; charset="iso-8859-1"

Hello,
Several months ago I asked about GRID1530 hard drives.
Several solutions were offered, one of which was to obtain
another drive from a list of bios compatable drives. I found
a Conner CP 3104 online and brought it in. The problem
is it is one and one half inches thick !.It dosent fit in the GRID
bay with the floppy.The original non-operational drive
was a CP3022 ,about one inch thick. The CP3104 is shock
mounted with rubber dounuts,making it thicker.
 Thought  I would post this to see if there is any mojo
 I can do to make it work before I send it back.
Thanks

  Oh yes...

  Using the original BIOS ROM you will need one of the following
  Conner CP3022,CP3024,CP3044,CP3042,CP3104

  The 1530 is model number sinsitave.  We have a program for you if you
  have access to EPROM programing equipment.

  Download http://groups.yahoo.com/group/RuGRiD-laptop/files/1530ROM.zip

  You will find the file "1530ROM.EXE". Go to a dos prompt and execute that
  file.  You get a screen full of hex code with questions at the bottom.
  e.g number of cylenders and so fourth.

  When this program is compleated it will generate even and odd bin files
  for your 1530 in a subdirectory named for your drive model.

  This is limited to 16 heads 1024 1024 cylenders and so fourth.

  Also there are several of us who would like to use compact flash for that
  application.  What is needed is an ATA-boot patch for the 1520 & 1530
  roms

  This will also allow you to use any drive

I own 2 Grid 1520 laptops. They where both working fine when I 
booted them 6 months ago, but now one of them gets an invalid 
configuration 02 error. After searching the net I determined that 
the connor HD was bad. Since I owned two Grids, I decided to swap 
the hard drives to prove that one of the drives was bad. When I did 
this both hard drives worked in one of the Grids and I still 
received the 02 error on the other machine. Does anyone have any 
thoughts on this? Can I update the BIOS in case it went bad? Also 
the grid with the error 02 is able to boot from floppy find, but 
cant see the 'c' drive.

Well I swaped out the ROMs with another set. Also I removed the CMOS 
battery with the idea that this would reset to some default state. 
After this I still get the error. I have run out of ideas.

HHmm...I'm kinda out of ideas.  However, I do have one

Does your 1520 have a modem?  Try removing that and
see what you get.
With the keyboard end of the motherboard, the modem is
located on the right side, between the battery/power
supply compartment and the case.
It plugs straight down into the motherboard and can be
pulled straight up and out.
Give that a shot and see if that works.

I tried taking the modem out, but no luck. Last night the other 
computer gave me the same error 02. I rebooted -cntl-alt-del about 
10 times in a row and it booted. I backed up the hard drive. Tonight 
I tried it again and it will not boot. So.. I have two 1520s that 
have the error. Both of these computers are the same age, and I 
suspect that the CMOS batteries have died. These machines both have 
the DS1287A chip inside. I am planning to order the replacement 
DS12887 chip and solder it in. I am interested if anyone has done 
this to know if this replacement chip will work on the motherboard. 
Does anyone out there have any thoughts?

Wow, I was able to get one of them working. I bought a new DS12887A 
chip unsoldered the old DS1287A and installed it on the motherboard. 
This fixed my configuration error 02! *Note I was not able to 
install a chip adapter between the motherboard and the DS12887A 
because there was not enough room between the board and the 
keyboard, so I soldered it directly like the old one was.

I've used my Grid 1535 for data collection with various home brew
interfaces.  Examples are water pressure monitoring for a house without
a regulator and traffic count including speed data from a radar
detector.  Thr Grid didn't seem to mind running 24/7 for a week.  When
the hard drive went bad I continued with floppy only.

 Well for one thing, you can kick its memory
up to 8 megs with low profile SIPPs, change the
HDD to a larger size, and then use it for most
of the things people use Laptops for, with the
exception of wi-fi, watching DVDs, or other
newer developments that most people don't
exploit anyway. Also with the assurance that
if you drop it, it wont fall apart into splinters,
and with a plethora of "obsoleted" free software
available. If gaming is your thing, you're better
off using a dedicated gamer machine than a much 
more expensive new LT in any case.

I have a 1450SX and ,like you, converted to DOS6,2. I found a DOS based
package program by PFS called 'First Choice' which has a simple word
processor, a good database and spreadsheet and a communications package
which is of little use these days except for the library. It is a very
reliable program with an excellent manual to guide through the intricases of
the database formulae. Is this what you are looking for?

Subject: Re: [RuGRiD-Laptop] GPS add-on

An example...  DeLorme has a "puck" GPS antenna that outputs NMEA format
to an RS232 port.

Pros...  you don;t have to set the device up to talk to your GRiD.  The
software usually already knows NMEA format.  The format and the tiger
lines files from the USGS are all published publically for free so if you
wish to brew your own GPS application the info is there for you. 

Cons...  There is no display on a "puck" so you have to have a laptop to
use it.  (this can be a problem in the car as some states have laws
against that).

Hey Andre,
Welcome to the group.  I thought I'd share your
message to the rest of the group because it was
interesting.
I have 4 1520's laying around in different states of
disrepair.  I really should get them all back
together.

Anyway, I am curious to know if you know what the
hospital used the 1520's for?

Thanks,
-Shawn

Hey!

Thanks for the swift and positive welcome.
Yes, I'm curious myself about what it was used for, but it is not
registered in any way, & I just picked it up today so I'll have to
ask around and get back to you on that. It has a 34013 VGA/EGA/Mono
cartridge but no battery or power supply.
I just connected power to it anyway and it comes up with Phoenix bios
v. 3.06 3/11/89, 640k base, 1408k extended, Invalid configuration
information; code 02, press F1 to continue. So I pushed F1.
The harddisk spins but it tries the floppy and says Disk Boot Error.
I'll have a look around in here and see if I can make a boot diskette.

Yes, with 4 of these around I'd guess you'd be able to make at least
1 or 2 of them work. They are a unique and cool design and as such
has a historic value, plus they can be used for simple tasks.

Regards
André

Andr,
I sounds like the hard drive may have died.  What I've
noticed is the berings fail or the hard drive can no
longer spin up to the proper speed.
For a boot disk, you can go to the Files ares of this
board and download DOS33.exe.  There is also an info
file so you can make your old boot disk. If all else
fails, you can go to www.bootdisk.com and download one
from there.  Just be careful with the adware from the
site.
Good luck,
-Shawn

Yes, I did manage to make a boot disk and start it up from that, and
I tried to set the harddisktype (3?) with conf1520.exe but it only
says command not supported on this system.
HD sounds like it spins normal & stable speed.

from the HD and uses that data to set the CMOS ram automatically..?
Got to go now, I'll be back on monday.

From: Charles Ford
Subject: Re: [RuGRiD-Laptop] New User/Hospital GRIDs

There are many stories about the GRiD ruggedness. 

My 1530 has survived an automobile accident. The Ice cube in a cocktail
shaker ride did far more damage to the interior of the car then the case
of the grid.  Also there was a three food flat drop to concrete.  The
drop did in the hard-drive but it lasted long enough to recover the data.


I remember the us army purchase of the GRiD Compass and the subsequent
"GRiDcase" 1520 units.  Back in 83' I witnessed the death of a brand new
UGC74 (digital teletypewriter with a drum printer and some word
processing features was the predecessor of the GRiD).  During the
"upgrade" from the older UGC4 mechanical teletype and UGC64 punch tape
recorder, a UGC74 was placed on the tailgate of an M74 (76 Dodge pickup)
to be carried out to the radio teletype rig which was to receive the
upgrade. When the truck shifted from 1st to 2nd gear the UGC74 slid off
the tailgate, hit the pavement and literally shattered.  it was a total
loss, there where millions of tiny pieces of the case and printer
mechanism.  Many of the 74s had severe mechanical problems and broken
cases resulting from pre-install handling.  The army was not happy with
the units.  

The GRiD case alloy was specially selected for its drop hardness, The
alloy has an aluminum to magnesium to chromium ratio similar to that of
an alloy house key.  The aluminum is soft enough to prevent shattering
and the magnesium rigid enough to prevent case distortion (bending and
denting)  Chromium is added to raise the ignition temperature.  This
alloy is borrowed from the aircraft industry and was the case material
used fro the RATT (Radio Teletype) radio equipment, GRC106 (If I remember
correctly) and the PC/XT (compass) and AT (gridcase) generic
configuration of the systems made them versatile, easy to interface to
the existing set of modems via RS323 and 232 to 234 adapter.  The generic
system configuration could also handle much more complex encrypting
schemes for the cold-war communication needs. The serial port was
configurable to use the old 6 bit teletype codes so it could connect
directly into a network that had remote stations with UGC4/UGC64 based
interface.  

The DC power requirements was an additional plus as the GRiD could use
both the 27V and the 12V DC power that was available for the Army radios.
  1986 this was extraordinary performance.  One hunk of equipment
literally took the place of three.  The UGC64 recorder, one of the AC
inverters and the external encryption equipment where simply no longer
needed. The problems 64 based classified trash (punch-tape) and a hard
coded external encrypting device was also eliminated and replaced with
software and an emergency incendiary self destruct (in case of capture)
This also eliminated the problems of operators not being able to
synchronize the encrypting gear. It could be loaded from a floppy or
cloned through a serial port. 

I have installed Windows 95 on my 1530 successfully although little else
will run. WfW 3.11 is about the most you can effectively use but this
will attach to networks and communicate with 98 based systems.  I have
not yet been able to communicate between a 311 based system and windows
XP.

Hey Andre,
Welcome to the group.  I thought I'd share your
message to the rest of the group because it was
interesting.
I have 4 1520's laying around in different states of
disrepair.  I really should get them all back
together.

Anyway, I am curious to know if you know what the
hospital used the 1520's for?

Thanks,
-Shawn

DrPhil,
I happened to be online as your request entered my

before retiring for the evening.  I approved it (as
you can tell).

While what's left of GRiD is now in the UK, the older

(80286) was built in California.  Depending on the
time, it was built in Milpitas or Fremont, CA.  I'm
originally from the area (Newark to be specific). 
Now, I'm over 3,000 miles (almost 5,000 km for those
outside the US) away from the area.

History aside, I'm really curious to know how well
they survive (or don't survive) an EMP.  Be sure to
let us know of your results.
Several years ago, I made a joke to a friend saying
that the cockroaches will be using GRiD computers!  If
us humans nuke ourselves away, it may be true!!

Gary,
If you happen to come across a source for SIPP memory,
I'm sure there are others that would be interested.
It looks like standard SIMM's with DIP pins on the
bottom.  I tired to find the maker of the pin or a
vendor.  I unsoldered a few from a SIPP and mailed
them to Newark Electronics, Mouser, and Digi-Key and
they all replied that the don't have them.

Subject: Re: New User/Hospital GRIDs

Thanks for sharing all this interesting info.
The storys behind are as interesting as the machine itself.
I found the source of this 1520. It turned out to be my boss. He
bought it for personal use in 1987, at a bargain price of approx
$6500.-, and has been using it until just recently, when it lost
contact with its harddisk. He was pleased that I had picked it up.
It has taken me a couple of days to read through all the posts here,
but it paid out in the end. Thanks to Greg Renno for finally making
it clear that a bad battery in the &Ł@$%#¤ Dallas chip makes it
impossible for the machine to find the harddisk. I'll be trying to do
some surgery on that chip now, making the battery eternally external
to it. There must have been dumped tons of equipment because of this.
Hope I won't run into that password problem that has been mentioned..
How about compiling some faq files for the different machines?

Here are some other info, & questions, I found while poking around:
The machine draws 2.25A with a lot of text on the screen, and "only"
1.5A with the dimmer switch on low.. 1.25A is as low as it gets with
the VGA cartridge in place, which is responsible for 200mA of this..
The plasma screen is plugged on 20pin header P2. What is the use of
the 26pin header P3, right beside P2 on the graphics board?
On the mother board there is a 34pin header P5 that I understand is
being used for a modem, but can be adapted for extra com ports.
Near the disk bay there is a 2pin molex P3D, and a 4pin molex P9C
that have nothing connected to them. What might these be used for?
There is a potentiometer RV1 below a hole between the ROM-DOS
sockets. It it possibly a brightness adjustment?
There is an electrolytic capacitor C11 next to the power input. It
decouples the 5V supply, is 1000microFarads 6.3V, and has been
mounted the wrong way around on my machine. It has almost blown up..
Anyone else seen this manufacturing mistake?
The 16V barrel input charges the battery with 250mA, via 20 Ohms
resistor R47 and diode CR19, even with the power switch turned off.
This current goes into battery terminal P4B, and P4D (the leftmost,
as seen into the battery box) is negative (gnd). Anyone have a
diagram of the internal battery pack configuration?
What's the story on the ROM-DOS chips and the 'Alien' sentry terminal
emulator program? Anyone with a source for these now?
Btw, I found some IDE/ATA info on the net. I don't know if anyone'll
have any use for it but here are the links:

I think this is a good source for the sun nvram surgery page, which is
what you have in nearly the
same form.

Older sparc stations used to suffer from this and had to have them
reinited or cloned.  This is a
good rendition of the repair instructions for those.  I had a couple of
sparc2's that I did this with
and it was fairly simple.  the battery used to be piggyback on the
memory, and if you removed the
pins from the side of the old chip carefully, you would have leads
sticking out to which to attach
a new battery (or holder if you were smart).

the sun startup made it easy to reconstitute it.  That info is of no use
here of course.

It is for the LCD screen.

I am not aware of using P5 for extra comm port(s). 
However, I'm sure nothing is impossible.  For a while
on ebay, a person was selling the RS-232 pod that
slides into the pod/battery bay.  This is one way to
get extra serial ports.

The metal battery compartment housing should have
connectors going from the "pod bay" to the P3A and
P3B.
This allows you (as the expense of not being able to
run the Grid from the battery) to connect external
periphials.  I have a 10Base2 network pod and a
IEEE-488 (a.k.a. GPIB) pod and they slide into the
battery compartment.  I have yet to try to get these
to work.

Not sure, but it would be my guess or it could be an
over voltage shutdown adjustment for the plasma
display.  I haven't played with it.

I have made an adapter for serial use. Here is a schematic.

Phil,
The 1520 is powered by 16 volts at the barrel
connector at the rear of the unit.  Tip positive.
You're in the UK, right?  Is there a Tandy (a.k.a.
Radio Shack) store near you?  I'm sure they'd have a
connector for you.
There is an AC to DC converter availible that slides
into the battery pod bay.  I see them on ebay from
time to time.
Let us know if you need more info.
-Shawn
P.S. I made a mistake in an earlier post.  Grid
Systems was located in Mountain View - not Milpitas as
I had said before.

Subject: What do we need?

OK guys and gals.  I'm looking for input.
Let me give a little bit of background information.

I subscribe to Nuts and Volts magazine.  I have been
involved eith radios and electronics since I was 11. 
I'm now 38.  I work in the electronics industry and
I'm a ham.  More and more, as I look through the
magazines, I'm feeling left behind.  Articles are
there talking about programming USB interfaces, and
doing a lot og high tech stuff that seems like it
would need zillions of hours to come up on the
learning curve.

So what's this have to to with Grids?  Well, not much.
 Only I keep having the feeling that with the current
technology availible at the hobbyist level, we should
have cracked the IDE interface problem in getting our
Grids to work with other IDE hard drvies.
I know Charlie has done a lot of work in getting the
1530 to work with other drives.  But what about the
1520?  If a person can figure out how to run Unix on a
Gameboy advance
(www.kernelthread.com/publications/gbaunix/),
collectively, we should be able to put together the
resources to figure out how to get a 286 BIOS to talk
to different flavors of IDE drives.

Now this is the part where I feel "left behind." I
don't know what pieces of test equipment it would take
to reverse engineer the interface.

What software package(s) do we need?  What pieces of
test equipment?  I've been through an Intro to C
Programming course.  I've got a Freescale (ex-Motorola
Semiconductor) 56F800 demo/eval board.  Can we throw
together some code and possible emulate a compact
flash or use it as a logic analyzer to monitor the
communications between the processor and EPROM?
A while back, we got some good info from the member
named 'perlhacker' but I don't know how we was able to
decphier the assembly code.  I asked to info on how he
did it, but I didn't get a response.

Anyway, I can't help but feel that we have the tools,
the knowledge, and the technology to get the 1520 to
boot from compact flash or some other IDE device. 
It's just finding the right people with the knowledge
on how to fo it.

Anybody have any ideas?  I'd really like to get my 4
1520's back together and working.

Thanks,
-Shawn

We need to talk to someone who has written a bootloader. 
Durring bootup the bootloader is the part that sets up the necessarry
device tables for the oporating system to use. Once we can locate a
device table we can explain to DOS what those device parameters are.

 I don't have the capabilities but I've always thought
that something like the overlays provided by the
various hard drive manufacturers, which get past the
drive size problem by fooling the BIOS as to the size
of the HD is the way to go. I've always thought of
bootloaders in relation to LINUX. LULU etc. Are they
the same as overlays ? Something about upper memory
modifications come to mind.

Subject: Re: [RuGRiD-Laptop] Digest Number 421

There was another thought I wanted to add to my
previous post:
What does it take to "roll our own" BIOS? 
Realistically, what does it take to make a BIOS?  Are
there any open source BIOS projects out there?
If a person went to Award or Phoenix or somebody and
said, "Look, we're a hobbyist group.  We want our old
286's to be able to boot from moder drives.  What
would it take?" would they die laughing?  Are there
such things as Software Development Kits (SDK's) for
BIOS?

Addressing the posts below, I've wondered how the
overlays work.  An overlay is software that resides on
the hard drive to fool the BIOS into thinking it's a
different drive with other parameters.
If you can't boot from the drive, how can the overlay
be loaded?  It's kind of like the "chicken and the
egg" scenario.

I wouldn't think we need a bootloader.  A bootloader
loads the OS.  The microprocessor needs to be able to
read the drive in order to load the bootloader.

-Shawn
P.S.  And Lawrence, it's LILO (LInux LOader), not
LULU. ;)

 I believe both the Overlays and bootloaders are
installed in the Master Boot Record(MBR) a small
sector at the beginning of the HDD. I imagine this is
what Partition Magic also manipulates. Partition and
format, etc, info is stored there as well.

 I imagine that the BIOS interrupt 13 gets the device#
and settings.  There's a good site on bios' at
http:/bioscentral.com

Hello,

Unfortunately,

Hello KB and welcome to the group.
Off the top of my head, my guess is the hard drive is
bad.  If it is the original hard drive, it is
approaching 15 years. Usually, the disc siezes or the
head sticks to the platter and keeps it from spinning.

Maybe another user of the group ans a suggestion.

I've seen some posts re. this problem. (Error code 02) It seems to be
related to the cmos battery being worn out.
I'm in the process of swapping the DS 1287 chips in my own Grids (1520 +
1530), hoping that it will solve the same problem.

I too have the problem, and have been a member for awhile now, listening
in.  The general issue is as described, and there are other reasons too.
The CMOS battery is likely dead as well, which prevents the system from
being able to recognize the drive.  I am not very good at fixing these
things, and wish I was.  But I also heard it's difficult to get to the
battery.  The hard drive is also VERY proprietary, meaning that the CMOS
only accepts certain Conner type drives.  There are ways to get the CMOS
changed to read newer drives, but I am not sure of the steps.  There are
files in the group that help you. For info, I found a replacement drive,
online, 20MB (geez that's small), and they only wanted about $350 US for
it!  Repair of the original was only a few dollars less.  Man that shows
you plain the theory of supply and demand.

Been a few years since I messed with my Grids, but a
couple things to try. If CMOS is dead, should still
fire up from a boot disk (if doesn't automatically
boot from floppy, hold "F" key after RAM check. Try
running setup again. If it will not recognize hard
drive from "A" prompt, then chances are good that HD
is bad, or setup corrupted.

You're right about the battery being difficult to reach. It's located
somewhere underneath the lower left hand corner of the keyboard. And
unfortunately, the DS1287 (combined cmos + real time clock + battery) isn't
socketed. Consequently, you have to take the computer very much apart, in
order to get the motherboard out, so that you can desolder the chip and
replace it with a new one. (You may want to use solder wick instead of a the
vacuum thingie. It's much easier to desolder it that way, without damaging
the pcb)

If you can get at it without yanking the MB then maybe you can cut the
pins on the chip close to the chip 1 at a time then yank the chip out
and leave the pins behind, you can than remove them 1 at a time or
solder the new chip to them.  I know its a hack but might be easy than
yanking out the board.

I have replaced the DS1287 on two 1520 Grids and been successfull.
You may want to search for my earlier postings. I would suspect that
a great many machines will be getting the dreaded 02 error as those
batteries where built to last about 10 years (Mine was dated 1992).
My two laptops gave out within months of each other over the last
year! With the replacement chips installed they have been working
like new. It should be noted that I was not able to get to my 'C'
drive even when I booted from a floopy until I replaced the DS1287.
It was a real pain to replace -Had to take the entire grid apart to
get the motherboard out, then using a desolder gun getting the old
chip off and holes cleaned out for the new chip. But I had never
used a desolder gun before and was able to fix both of them. I'm
still suprised I didn't ruin the motherboard!

Good luck,

I am very interested to purchase a Grid laptop.
Even one of the earler models will do, providing it works ok.
Wondering where I can find a secondhand one, & how much they cost.
I will only be using it for DOS applications.

Hi Chris.

I have four Grids, all bought on eBay auctions. That has worked well for me,
since i live in Denmark, where Grids are kind of hard to come by.
The prices varied between USD 20.00 and USD 120.00. Shipping varied between
USD 40.00 (surface mail) and USD 70.00 (standard air parcel).
Apart from the usual problems with the Grids (mainly a dead cmos battery,
which makes it impossible to boot from the hard disk), they are all in good
condition. Quite a few of the auctions have restrictions on where the seller
is prepared to ship to. I've had luck with two of mine, asking nicely if the
seller would consider shipping to Denmark.

Be prepared to wield the soldering iron if you get a Grid that has the
Dallas DS1287 / DS 12887 RTC chips. (Mine are 1520 and 1530's. They all have
that chip and none of them work at the moment) They have a built in battery
that serves, not only as a battery for the clock, but also for the cmos ram
that stores the needed setup parameters for the bios. The batteries are
non-rechargeable, and have a lifetime of app. 10 years, and when they die,
the bios stops recognizing the hard disk. You will only be able to boot from
a floppy if that happens. The 1750 that i have seems to have a rechargeable
cmos battery.

Brgds,
Gert Christiansen

This is the best price I could find:
http://store.yahoo.com/battstore/daldsds12887.html

This is where I bought mine. You will probably want to get the 
12887A not the 12887 as the 'A' version allows the password if set 
to be reset. Details on the chip can be found at 
http://www.maxim-ic.com/quick_view2.cfm/qv_pk/2682 
Good Luck. Removing the old chip is the hardest part. I used a 
solder 'sucker' and carefully slid a small screwdriver under the 
chip and would pry a little and reheat pins as necessary to unsolder 
it loose. When installing the new chip I used a butane solder iron 
with a pencil tip.

Hi, My gridcase 1520 is dead, completely and buried.
So, Is it possible to use the plasma screen (the red one) on any
regular PC?
I was thinkin to make a diagnose PC for a on-board car performance
utility software.

What add-on circuit do I need?
It has a 20-pin connector inside of it.
It´s a NEC red lasma display.

And I don´t know the model, datasheet, reference, etc.
Any help is welcome.

Thanks,
Celso

I just got a Gridcase 2 in semi-working order, it boots from a floppy

It has DOS 2.11, GWBASIC 2.02, XTALK 3.61 above the keyboard and 123

If anoyone has any info on this could you help me out?

A little background:  Iv'e also got a couple of 1550SX's that work 
perfectly, a 1530 that does the same, and a couple of 1660's that 
work but the keyboards are a little flakey.

There is a place in the configuration utility where you install the ROM
as a drive.  (I think).  Use CONF1520.EXE /? to query the configuration.

Subject: Grid software and ROM images. (archive)

Folks:

There are many GRiD specific software files and ROMs out there.  

Let's -> Find them
   
         Analyze them

         and

         ARCHIVE them.

I have acquired an old ROM burner. I do not have the software 
yet, however; I also have access to several machienes at work. 

If anybody is willing to send me a ROM or any other GRiD firmware /
software.  I am more then willing to archive an image and send the 
original hardware back to you.  

I would then begin to compile a GRiD support CD that contains all
of these files.  I would even like to place manuels / images on this 
CD.

So in the future, hopefully, the correct answer to "Do you have a copy of
<?>" will be "It's on the CD"

BTW, Will this CD include anything for the Compass/GRiD-OS or any versions of

Hey everyone,

Comment from user:
our store recently got a donated gricase 2 machine.
"Bad or missing
Command Interpreter" is the startup message, and i was
trying to find a
way to fix it. 

IIRC, the Gridcase 2 is a 8088 machine circa early
1980's.  I can't remember if that one boots from
floppy disk or ROM.  If it boots from ROM, it means
the ROM chips are bad or missing (probably missing).
If you could find an old DOS boot disk (like DOS 3.3)
you could get the computer to boot up.

I hope that helps,

For the new user.  I am not totally sure if the GRiDcase II is a
GRiD#1520.  If so then it will run MS-DOS 6.21 nicely. Also remember to
use the "F" key trick to force a floppy boot.

A 1520 is an 80286 / 80287 system capable of holding up to 8MB of ram and
running windows 3.0 or 3.1 (in non enhanced mode)  

If someone could read off the model number for a GRiDcase II and GRiDcase
III it could prevent a future of continued confusion.

Hello Alpina,
The 1520 is an early 90's vintage, 286 computer with
up to 4 MB of memory.  Typically, they have 1 MB of
memory.
If your Grid has a hard drive in it, the odds are that
it doesn't work.  A few of the Conner drives from that
era work, but not many.  There are only 3 models of
hard drives that it will support and I think 40 MB is
the largest drive size of those 3 models.
If you have the power supply, plug it in and turn it
on.  See if it still powers up.  If you don't, you can
find the barrel plug for it at most elcetronic stores.
 If you're in the US, Radio Shack sells the plug.  The
computer likes to run from +16 volts at about 2 amps
at startup.  Just after startup, the power drops down
to about 750 mA.  12 volt power supplies are more
common, but I haven't had good reults from trying to
get the Grid to boot from a 12 volt supply.  14 volts
is probably the lowest you want to go.

Good luck and let us know if it works.
-Shawn

Charles, Charles, Charles...
Where have you been?  ;-)
I already did.  I've posted my results, (or lack
thereof) many times.  I've even emailed you privately
about my failure of getting my Grid to boot from
Compact Flash.
The BIOS file is in the Files section of this group. 
There is the merged file as well as the individual odd
and even files.
The drive table starts at 0x5038h and lists the
CP3022, CP344 and the CP3104.
The brickwall that I hit is that I could not find the
Cylinder, Head, and Sector (CHS, a.k.a drive geometry)
information anywhere in the BIOS file.  I searched
forward, and backward using big Endian and little
Endian notation.  I tried adding the cylinders to the
heads, the heads to the sectors and couldn't find the
right numbers.
Maybe someone else can.
Anyway, the files are in in the files section.
Enjoy,
-Shawn

Alpina,
I hope you don't mind that I reponded through the
group.
Since I added you to the list, you should get this
email.
I have never heard of an Alps DRP020A hard drive in a
Grid computer.  In fact, I've never heard of an Alps
DRP020A hard drive.  My guess is someone else added
the drive after the original Conner failed.  The other
possibility is it is somehow compatible and, at one
time, it worked.  However, as far as I know, only
three Conner Periphrials hard drives work in the 1520:
the CP3022, CP344 and the CP3104.  I don't remember
their sizes, but I think they may be 20 MB, 40 MB and
40 MB respectively.  The reason these drive are the
only ones that will work is because these model
numbers (and parameters) are hard coded into the BIOS.

I hope that helps.
-Shawn

Sorry Wilf,
I don't know why.  Maybe because the 1450 user have
not been as vocal as us 1520 and 1550SX users.

There's no accounting for taste.   I'll have to admit to being pleased 
with the 1550sx.   The only problem with the one I have is that I had 
to put an LCD display on it when I screwed up and lost the power supply 
for the plasma display.    The hard drive has some errors on it but I 
happened to find one in a surplus store that (I was told) checked out 
OK.

   Admittedly I haven't been playing with the Grids much since I 
started fooliing around with the Itronix stuff but I still have the one 
I like in assembled and (I hope) still working condition...and, of 
course, a box of stuff that I should be able to assemble into at least 
two more...I'm not going to say that it will ever happen, mind you.   
I'm afraid that the box of disassembled grids is up in the attic right 
next to the two Osbornes that I was guessing I could make into one 
working one... 

 Yes, I have a few 8 bit machines hanging around taking up space in the 
attic.   I have a couple of Commodore SX-64's; one working and one for 
parts, a set of schematics, extra disk drives, a bunch of accessries 
including a Prom Queen, ComputerEyes, HexMon cartridge, light pen, and 
a big box of old software.    I see no reason to get rid of any of it 
myself...although my wife might be able to come up with an argument or 
two...

Shawn,  Thank you for the kind reply. Perhaps not too much goes wrong with
the 1450, although I doubt that, Mine
decided  to  refuse to boot about 6 months ago. Nothing seemed to make it
work; start up disk, nothing. I despaired thinking it must be the CMOS
battery. I let it sit as I couldnt face that task. Last weekend I switched
it on and it booted as though nothing had happened. All data seems intact
and the disk is undamaged according to 'Scandisk'. How do you explain that?

Roger,  Thought I had a CMOS battery problem but after months of playing
dead, I switched it on one morning two weeks ago and it booted up as though
nothing had happened. It seems OK. I don't understand what caused this and a
number of similar inexplicable computer tricks. I think perhaps I am

press <F1> to bypass the error
cycle the power once (about a half second)

The 1520 shoud respond "real time clock not set"

The CMOS battery is dead

If you press <F1> it should now boot normally (once)

Not all 15XX are the same in this reguard
Some have a dallas RTC others use an MC68818 and a seperate lithium cell.


Other problems you may encounter:

The hard disk is not running or not set up,  The unit will try to boot
from the floppy.

When there is a valid partition on the hard drive but no oporating system
the unit will try to boot from the hard drive and just lock up.
To bypass this (allowing you to format the drive) press and hold the
letter "F" (for floppy) it will force the unit to boot from the floppy.

Subject: GRiD items for sale

Hi, Guys,

I've reluctantly decided that the time has come to part with my GRiD 
collection, and I'd like to offer it here before putting it on eBay.

I've got (at least) a Compass, the matching Hard Disk and 5.25" 
floppy drive unit for the Compass with the IEEE.488 lead, my much-
loved GRiDCase with a red screen, a GRiDCase with a damaged LCD 
screen, and a lever-arch file of various information about GRiD 
software.

I think the Compass is of sufficient technical history importance 
that I might consider putting it into one of the occasional 
collective auctions of technical items that a couple of the big UK 
auction houses run, but if anyone is seriously interested in 
purchasing the whole collection, perhaps they could email me off-list?

best regards,


Bob

Thanks for the input.

 

I am wondering if there is a good source for a FAQ regarding current issues
with GRiD laptops (I have a dead 1530 thatI'd love to repair reasonably),
common failures (the CMOS issue!), how to get them up and running, and
possible upgrades folks have successfully completed.

 

Lastly does anyone know where to purchase a new battery (refurbished I would
assume).

 

Thanks for keeping this group alive.

Hey crew! I picked up a Panasonic Toughbook CF-25 the other day. Since these 
are kinda like the Grids, I'm wondering if anyone has any experience with 
them. Two questions if anyone knows about them:
1. What is the antenna on the left of the screen/lid for?

2. Is there a site for downloading a manual for it? I've searched two nights

I have the CF-27 Yellow top SBC unit($20 at 1st Saturday sale, dowtown
Dallas, TX.)
Should be similar....
Antenna = CDPD/GSM modem
Website = www.panasonic.ca/english/customercare/downloads.asp
(Should have everything you need to get it going or change operating
system if you want to)

Is your unit complete? 
Mine is PII/300mhz
Mine had the battery & HDD caddy when I got it. 
I have added: 
128mb ram (192mb total)[$30]
floppy drive (e-bay)[$9]
Power supply (Laptops for Less)[$50]
I'm running Win2000 on a 3gb HDD.
Not too bad for $110 investment

Hi Cody,

Mine was 75 bucks CDN, too much but I'd only seen them on ebay before not on 
craiglist. Mine is a dog, P166MMX with 64 megs of RAM (max 96 I think) but 
it came complete with 4 gig drive, cd and floppy which are interchangeable, 
good battery which seems to run for hours (no fan so it is silent and saves 
power), plus the car adaptor. Black case with no obvious marks and a perfect 
screen. I guess I got a bit of a deal in retrospect.

Thanks for the links, I looked all over the 'net for these and came up dry. 
The manual still doesn't mention the antenna but I guess it's really 
irrelevant since it would be useless. I thought it was a wifi antenna or for 
a gps. That would have been cool!

The problem I have now is trying to install an os without a permanent 
floppy/cd combo. There are ways around this but they seem finicky. It came 
with KDE but the root password wouldn't work so I installed ubuntu right 
from the cd but that was far too slow. I'll go with w98 as soon as I work 
out the boot problem.

 A wonderful Laptop. Now if it only didn't come with

 Surely Grid knew that the Conner HD was a dud, and
that putting the BIOS on a battery was a sure path to

Subject: Re: [RuGRiD-Laptop] Digest Number 460

 I still like the option of changing the BIOS to
accept
larger drives or even a cushioned drive that was
mentioned in an earlier post for ruggedised LT .

 My current favorite is a Dauphin DTR-1, a sub-mini
notepad that uses Win3.1 for Pen but to make it really
usable I have to use an Iomega PP Zip HD and an
external modem. I also just bought a Backpack CD-ROM
with  independent Sound card so I could use it with
SB-type programs and play CDs. Since it has an abysmal
battery pack, away from AC or automobile I must also
use an 8lb 12v DC supply. And once I get set up with a
GPS reciver, I'm almost carting around the equivalent
of a desktop. And there's also the mini FDD. 

 I just figured out that I could likely sell the whole
damn thing and buy a thinkpad with all those features.

 Similarly with my beloved Grid 1520 and its red
plasma screen. I have upgraded it to 8megs but then
the damn internal battery goes lame and I have to get
one and solder it in because it also contains some
BIOS. I love the beast but it is heavy, and adding a
bunch of external peripherals just adds to the
complications. Oh well nobody said retrocomputing
would be comfortable.

 My third beast is a Sharp PC-3k, made as a follow-up
to the Atari Portfolio by DIP. For whatever reason
they made it with non-standard PP and serial ports.
Likely what Atari's Sam Tramuel suggested since he saw
added profits by selling nonstandard connectors. Sharp
snatched it up when Atari rejected it, and it is a
remarkable little handheld, with DOS 3.1 and a bunch
of other excellent programs built in, including
Lap-Link(which of course is unusable unless you have
the cable and an adaptor to change it to standard PP
and serial port connections) and a 2400BPS modem. Has
2 PCMCIA 1 ports for simulated Floppies which can be
used with flash-card adaptors. It uses 3 AA batteries
but which it drains even in it's off condition. This
may have been an engineering fault.

 But for the rest, curses on all marketers and bean
counters, their children, and their children's
children.

Subject: Not doing much with the Grids anymore

I seem to be spending most of my time with the Itronix these days.  I 
suppose I should do an inventory of what I have in the way of Grid 
stuff in my project box and see if I can find a home for it...It won't 
happen right away, mind you, there's simply too much happening...I 
think it would be worth while to hold onto ONE of the 1550SX machines 
simply because it has the option of slowing down both the bus and clock 
speeds so it can emulate a truly ancient machine...sometimes a useful 
attribute. (and, of course the dual com ports make it a useful tool for 
analysing data transfers.)  Too bad I lost that high voltage supply for 
the red plasma display.  That would have been way cooler than the LCD!

Subject: new to 15xx Grids

  Hi gang, very glad to find this group.  I poked around over on  
Rob's GridBoard, but didn't find the answers to my questions.

  I've got a 1520 that supposed has booted and ran the last time the  
previous owner powered it up, but he hasn't used it in years.  I'm  
sure I'll need to replace the CMOS battery, that's no problem for  
me.  The display is missing some interleaved lines near the bottom,  
I'm hoping that's just a loose connection or cold solder joint in one  
of the display control chip / lines in the display head, and not a  
bad driver chip.  If so, I can find and fix that too.

  Right now, it doesn't boot from the hard drive (probably because  
the CMOS is corrupt) nor from any of the DOS boot disks I've fed it,  
but I suspect they were all 1.44 and it's a 740k drive, so that's  
still an open issue.

  I've got all the files from the Grid downloads archive, and should  
be able to build a boot floppy (with the config.exe program) once I  
find a USB 3.5" floppy drive that can format old DOS 740k disks! (I  
use Macs and Unix boxen these days)

  So my first question: is there an FAQ for Grids anywhere?  I  
suspect all of my questions are pretty basic, and I don't want to  
annoy you guys with questions that have been asked a hundred times  
before.  I'll wait for that answer before proceeding, and I'll try to  
look through the messages later today before I press on much further.

  cheers,

Subject: Re: [RuGRiD-Laptop] new to 15xx Grids

Hello there, Gomez.
My name is Shawn and I kind of act as moderator
emmeritus here.
I have 4 or 5 1520's in various states of disrepair. 
Our family cat has buried several pieces of one of my
1520's in a bunch of cat hair.  She likes to rub
against them.
That aside, let me try to answer your questions.
The main reason it won't boot from the HD is probably
because the drive is physically bad.  Either the drive
was used a lot, which causes the bearings to sieze, or
it wasn't used a lot which causes the heads to stick
to the platter.
If the drive does spin up, it may not be rotating at
the correct RPM.  The end result in all of those cases
is the PC won't boot.
I have heard that if you press the 'f' key during
boot, it forces the GRiD to boot from floppy.  I've
had intermittant results doing that and I can't say
that's a sure fire way to get it to boot from floppy.

I'm 90% sure the Grid will read 1.44 floppies.  I may
be wrong on that tho.  My memory is failing as I get
older. :(

As far as the missing lines on your display, my
experience has been that it's caused by rough
handeling/closing the case way too hard.  I suspect
something is wrong with the display itself and not
something as simple as connections to a chip.  If you
find out otherwise, please let us know.

A FAQ for GRID's.  No, not one here.  Maybe I'll make
one when I have time and motivation.  Don't look for
it anytime soon.

If I just could find a use for a 286 machine, I'd be
motivated to do something.
I haven't found any Linux versions that will run on a
286.  Are there any (free) Unix versions that will run
on a 286?
Thanks,
-Shawn

Shawn and Gomez:

Welcome to our group, Gomez! Hey, I got my 1520 to
boot from various 1.44 DOS floppies but I can't
install because--like just about every GRiD you can
find anywhere--the hard drive is dead (it spins but
the read heads are bad).  And try and find one--just
try finding one that has the same interface!

Shawn:  I have read that Minix (a "proto-linux", if
you will) will work on x286 machines and, while I have
the binaries, I haven't yet built the disks run them
on the GRiD.  I'll get around to it eventually (maybe
when I get laid off this winter), so I will let the
GRiD board know if I have any success doing so.

That "F" key thing almost never works for me, either;
I have to screw around for about 5 to 10 minutes
before I can get the 1520 to boot to a floppy, and
then I'm not really sure *how* I did it.  Sounds
pathetic, but it seems like the thing is just finicky,
or perhaps just old and slow--like a lot of us messing
about with these old GRiDs.

And, my display also has two lines missing from the
center.  It's not really too bothersome, but from what
I know of LCD screens, it's easier to damage the thing
more by attempting to repair it.  Since my GRiD is
never going to be one of my main computers, I'll just
let it go.

Nice to see some new activity on the GRiD board . . .

Well, I tried the usual "stiction" solution of simply
rotating the machine once or twice vigorously, and I am
pretty sure I can hear the drive rotating.

It certainly tries, but I don't think I have the right
floppy - the guy who gave me the machine is going to
get one to me soon.  I don't even have a way to make a
floppy any more.  :)

The previous owner says the same thing, so I'm gonna go
with that.

Well, there's Minix and Contiki, for starters.  They will
run on ancient small machines that won't run any of the
modern Linux variants.

There's also something called ELKS, which I know precisely
nothing about, but that is reputed to run on sixteen
transistors held together with chewing gum.  ;)

I've had no trouble getting it to "go to" the floppy.
I haven't yet got it to boot from a floppy though.
I have a honeymoon coming up next weekend, so it will
be some time before I get time to work on it again.

Subject: Ideas for IDE

All,
First off, I want to thank Gomez and 'e m' for the
Mimix, Contiki and ELKS links.  It has rekindled my
desire to get thing moving with my 1520's.  I am still
holding onto the dream of getting the 1520 to
recognize newer (and larger) hard drives.

An old email from Len mentioned BIOS Central
(www.bioscentral.com).  I went there and poked around.
 It appears that the site is geared for people who
want to reflash their BIOS or diagnoise POST errors. 
Nothing there really interested me.

Earlier, I had thought that the way to fix this
problem is reprogram the BIOS with an updated drive
table.  This presents a problem because I haven't been
able to locate the drive geometry (a.k.a. Cylinder,
Head, and Sector (CHS)) info in the BIOS EPROM.

Another idea hit me the other day:  what if we didn't
bother with trying to edit the BIOS?  What if we came
up with an interface card that sat between the GRID
IDE card and a newer, larger, hard drive?  The card
would report to the computer that it is a CP344.  This
card would pass all other data to and from the hard
drive.

Does anybody thing that doable?  Is it unrealistic?
Any ideas?
-Shawn

No problem.  found 'em with a Google search on "286"

But to do that, wouldn't you need to somehow install a
newer disk controller?  That sounds like major hardware
hackery.

How would you cram a new HBA inside?  I want this box

I still think that adding ATA boot capability is the best rout.  I think
we can grab an unused vector and patch in a 55AA signeture, read the ATA
table and dump the info into the boot DCT.

I don't think the patch will tak much, it is locating the damn DCT to
update the table that bugs me.

Allong the lines of using a drive ID hack.  You can do this if you create
a boot partision of exactly the same size (sector count) as the 3044 or
other approperate drive.  Then load a DDO to create the second partision
using the nest 2G of sectors.  Then just change the drive name in the
table.

 I have a SCSI pod which appears to use that method.
You can select one of 4 BIOS addresses "where in the
PC's ROM Scan Space the SCSI Controller BIOS will
reside." .... " in one of four available address
ranges
(CA00:0000 to CA00:1FFF, C800:0000 to C800:1FFF,
CE00:0000 to CE00:1FFF, and DE00:0000 TO DEOO:1FFF)."

 Could one possibly use one of these memory areas to
install an ATA BIOS ?

While moving recently, I found a box of accessories

6 years ago! I have a power supply with cord that goes
between supply and laptop, never charged "enhanced"
battery (who knows if it will take or hold a charge
after all these years!), a car cord, four network

eBay, but wanted to give the group first shot. $40
including domestic shipping. Thanks

DCT:  Device Control Table  (where the bios stores hardware info for DOS

DDO: Dynamic Drive Overlay Usually a .sys file that is called from the
config.sys durring bootup. This installs a secondary drive control that
allows a second partision larger then 504MB (up to 2.1GB) and as many
2.1GB partisions as will fit on the drive.

YES YES YES !!!  I think I saw a ROM socket in my IDE pod...  I will
check.  This would allow you to add to the boot sequence

I still think that adding ATA boot capability is the
best rout.  I think we can grab an unused vector and
patch in a 55AA signeture, read the ATA table and dump
the info into the boot DCT.

I don't think the patch will tak much, it is locating
the damn DCT to update the table that bugs me.

Allong the lines of using a drive ID hack.  You can do
this if you create a boot partision of exactly the
same size (sector count) as the 3044 or other
approperate drive.  Then load a DDO to create the
second partision using the nest 2G of sectors.  Then
just change the drive name in the table.

Subject: 15XX  "STUFF"

While moving recently, I found a box of accessories
for 1500 Grids. I gave away the last of my 1520s about
6 years ago! I have a power supply with cord that goes
between supply and laptop, never charged "enhanced"
battery (who knows if it will take or hold a charge
after all these years!), a car cord, four network
pods, and one Gandalf "mini MAU" IEEE802.3 10BASE-T
Transciever. All items appear new. Was going to put on
eBay, but wanted to give the group first shot. $40
including domestic shipping. Thanks

Subject: Open Question for Russ

Hey there, Russ.
I thought a flood of technical questions were going to
come to you.  I see that hasn't happened, so I'll ask
my question(s).
I am hoping you worked for GRiD Systems as a technical
person and not someone in, say, marketing or sales.
Here is my specific issue:
I have 4 1520's.  In the 1520 BIOS, it is hard coded
to only use the Conner Peripherials CP322 CP344 and
CP3104 hard drives.  These drives are over 20 years
old and most of them have failed.  I would like to be
able to boot the computer from a larger drive or,
better yet, compact flash.  
I've dumped the BIOS and found the text string that (I
think) is used to compare the drive.  The problem is I
can't find the drive geometry (Cylinder, Head, Sector
information) in the BIOS.
Can you tell me where it's located or, better yet, do
you have any ideas on how to get these older computers
to recogize and boot from newer hard drives?

Also, if you have any other neat, "gee whiz" info
you'd like to share, feel free.
Thanks a lot in advnace.
-Shawn

Hi Shawn, 
   
  I did work at GRiD as a systems tech and did some component level repair however it's been 15 years ago!  I dont remember enough about the BIOS to be much help I'm afraid.  Unfortunantly, I no longer have any GRiD parts or laptops around to play with.  I also worked for Conner Peripherals believe it or not before they got sucked up by Seagate and moved the tech support to Oklahoma City. 
  Does your 1520 have a plasma display? I used to specialize in fixing plasma diaplys of the of missing pixels. The drivers are surface mount and would often loose good solder contact....pretty easy to fix.  
  If I find something on the BIOS that I think might help you I'll pas it on. What's the current dive model that's in the laptop?

Hey Russ.
Thanks for the response.  I know it was a while ago,
but I thought I'd give it a shot.
I have both the LCD and plasma 1520's.
As far as the hard drive models, I think they all were
20 MB, CP344's.  I only have one left and it's very
intermittant.  I would guess it's bad now since I
haven't powered it up in almost 2 years.
Thanks,

Hello all,
 I have a GRiD 1750 and the hard drive is dead. Nothing boots up when
i turn it on (the screen doesnt even light up unless i push in the
little reset button on the side). I was wondering where I could get a
new hard drive for it. I Don't know of any places that sell them. I've
tried ebay  as well. Is my only hope a trade? any info would be great.
Thanks a lot
 Luke P.
 P.S If anyone has the specs for it as well that would be great too.
Thanks again!

Subject: Re: Open Qestion for Russ

 Hi guys. Haven't posted for awhile, just been
lurking. Also been concentrating my retrocomputing on
expanding the capabilities of my Dauphin DTR-1. Since
I also haven't replaced the RTC on my 2 1520s they're
sitting here anxiously waiting for attention.

 The problem with the CPC drives has to be the most
posted about issue with the 1500 Grids in this group
and the next one boot-up problems related to the RTC.

 I also held back figuring there would be a plethora
of questions for Russ. I also wanted not to scare you
away Russ. :^)

 Somewhere there has to be some documentation. Are you
by any chance still in contact with any of the old
Grid crew ? There must have also been an answer script
for the CSS GRiD Resource Center phone answerers such
as IBM had. Parrots are cheaper and need less training
than knowledgeable service-men. Which is why I almost
never phone a customer call center.

 I have several of the bus connecter pods. The AC pod,
the VGA, the SCSI, and of course battery packs. I know
there is also the
Ethernet and the IEE4xx(?) for controlling external
processes. Do you know if there were any others ?

 Did you have any familiarity with the EProm chips
(Grid called them cartridges). I'm wondering if one
way of overcoming the limited HD capacity and problems
with the Conners would be a HD overlay in the EProms
such as the ones used by numerous HDD manufacturers to
overcome size limitations in older Dos systems.
The SCSI pod documentation mentions some memory areas
its BIOS accesses to initialise its SCSI devices. With
that perhaps a simple code could be used by the EPROM
to access the DMA(?) and install an internal SCSI HDD.
Any insight on these problems with an otherwise
remarkable machine.

 When my main 1520 is working I have 8megs of Ext ram
on it. Too bad GRid used the now not easily available
SIPPs but perhaps it was because they were less likely
to become unseated under rough handling. For kludges
like me they are also difficult to insert, I destroyed
3 of the SIPP's pins when trying to insert them. But
what a rush when this 286 comes up with 7340k ext ram
available.

 In perusing my 1500 manuals I recently noticed that
the difference in top speed between the 1520(10 MHz)
and 1530(12.5MHz) was really negligable and they both
had a x87 coprocessor available. I find the red plasma
screen cooler than LCD displays in any case so my
thirst for a 1530 has receded. I wonder if the 1520
can use the 32s TTP subset like the 386SX ?
I have an old NEC 286 LT that can also use Ext memory
but was always under the impression that 286s could
only use Exp. mem.

 In any case welcome to the forum. As you undoubtably
surmised, you are more than welcome. Perhaps you could
breathe some life into what has been a recurring theme
of "how do I replace these #$@#%@ Conner HDs" and "Why
won't my 15xx boot." Maybe one of those Viet-Nam
veterans who dropped their Grids from helicopters
might show up on the forum to reminisce. :^)

 I still want an AFFORDABLE **NON-FxxKING**-USB GPS
receiver that I can use it with in my car. I even have
one of those huge "RARE" external 5 1/4" fdds and
cable that was used on the earlier model GRiDs or much
other stuff I would trade for one.  

 Excuse the verbosity, which you might have noticed
:^) ,but chat type msgzz I've found lead to confused
interpretations and misunderstandings. Besides, I like
to write. :^)

Hi Lawrence, 
  I'm not in contact with any of the old GRiD crew unfortunantly. I do however know guys at Seagate (formerly Conner Peripherals) but doubt that thel'll be able to shed any light on this.  
  Sorry that I cant be of more help with the peripharls on these units either! 
  Of coarse the big problem being that there are no updates for the bios, no way of flashing it that I'm aware of since the rest of the hardware is dependant on the firmware, not just the limitations of the bios but also the cpu and other components. 
   
  I have a much more recent AMD Athlon 750 that's in a Asus mainboard that I cant get a bios update to exceed the magical 125 Gig limitation. Thus I can only use half of my 125 gigs ( I hate using manufacturer's overlay)  
   
  Anyway, the only way I know of is to find old part for these laptops of which of coarse are in dwindling supply as they these old parts are dying away with the older technology. 
   
  Gotta go for now, at work,,,

I also haven't replaced the RTC on my 2 1520s they're
sitting here anxiously waiting for attention.

The problem with the CPC drives has to be the most
posted about issue with the 1500 Grids in this group
and the next one boot-up problems related to the RTC.

I also held back figuring there would be a plethora
of questions for Russ. I also wanted not to scare you
away Russ. :^)

Somewhere there has to be some documentation. Are you
by any chance still in contact with any of the old
Grid crew ? There must have also been an answer script
for the CSS GRiD Resource Center phone answerers such
as IBM had. Parrots are cheaper and need less training
than knowledgeable service-men. Which is why I almost
never phone a customer call center.

I have several of the bus connecter pods. The AC pod,
the VGA, the SCSI, and of course battery packs. I know
there is also the
Ethernet and the IEE4xx(?) for controlling external
processes. Do you know if there were any others ?

Did you have any familiarity with the EProm chips
(Grid called them cartridges). I'm wondering if one
way of overcoming the limited HD capacity and problems
with the Conners would be a HD overlay in the EProms
such as the ones used by numerous HDD manufacturers to
overcome size limitations in older Dos systems.
The SCSI pod documentation mentions some memory areas
its BIOS accesses to initialise its SCSI devices. With
that perhaps a simple code could be used by the EPROM
to access the DMA(?) and install an internal SCSI HDD.
Any insight on these problems with an otherwise
remarkable machine.

When my main 1520 is working I have 8megs of Ext ram
on it. Too bad GRid used the now not easily available
SIPPs but perhaps it was because they were less likely
to become unseated under rough handling. For kludges
like me they are also difficult to insert, I destroyed
3 of the SIPP's pins when trying to insert them. But
what a rush when this 286 comes up with 7340k ext ram
available.

In perusing my 1500 manuals I recently noticed that
the difference in top speed between the 1520(10 MHz)
and 1530(12.5MHz) was really negligable and they both
had a x87 coprocessor available. I find the red plasma
screen cooler than LCD displays in any case so my
thirst for a 1530 has receded. I wonder if the 1520
can use the 32s TTP subset like the 386SX ?
I have an old NEC 286 LT that can also use Ext memory
but was always under the impression that 286s could
only use Exp. mem.

In any case welcome to the forum. As you undoubtably
surmised, you are more than welcome. Perhaps you could
breathe some life into what has been a recurring theme
of "how do I replace these #$@#%@ Conner HDs" and "Why
won't my 15xx boot." Maybe one of those Viet-Nam
veterans who dropped their Grids from helicopters
might show up on the forum to reminisce. :^)

I still want an AFFORDABLE **NON-FxxKING**-USB GPS
receiver that I can use it with in my car. I even have
one of those huge "RARE" external 5 1/4" fdds and
cable that was used on the earlier model GRiDs or much
other stuff I would trade for one.  

Excuse the verbosity, which you might have noticed
:^) ,but chat type msgzz I've found lead to confused
interpretations and misunderstandings. Besides, I like
to write. :^)

Russ why not get one of the PCI cards that will add extra and most
likely faster IDE ports to the computer, I think that's all you would
need to do to access the whole drive.  I had a promise card in an old
abit BH6 board that worked like a charm.

Subject: 1520 flash issues

So it seems that, at the moment, getting the 1520 to recognize and use
a flash drive is impossible.

Has anyone tried disassembling the BIOS code in the effort to get a
flash drive working?

I don't have much experience with low-level programming on the x86,
but you'd think it'd be possible to sift through the code and find
where it starts talking to the hard drive.


My next thought would be to set up a logic analyzer to see how the
drive and computer are talking to each other. Reverse engineer the
propreitary interface, and then make a flash card controller out of an
FPGA or a PIC microcontroller to translate the flash card data into
what the GRiD wants to hear.

Subject: Re: [RuGRiD-Laptop] 1520 flash issues

Des,
Welcome to the group!
As far as disassembly of the code, I think there was a
start by another number (Eric?) but, like most other
project, it fell by the wayside.  I've dumped the BIOS
EPROM contents and it's in the 'Files' section of this
board.
And I have virtually no experience with low level x86
stuff either.
I have access to some pretty nice logic analyzer at
work, but I'm not sure on how to set it up and what it
is I'm looking for.
And, I agree.  I think an ASIC or FPGA is needed
between the "motherboard" and drive to fake out the
BIOS.  But, basically, this ASIC would have to be a
whole IDE disk controller.  Seems kinda hairy...

Subject: 1530 memory into 1520?

I have a 1530 that seems to be completely dead. It has 8 megs of RAM,
can I take out the 8 SIPPs and put them directly into my 1520?

The 1520 only has one meg, currently.

I am kind of scared of taking apart the 1520 and breaking something,
since it just works so well as is. Even that ancient Conner hard drive
works as good as it did the day it was built, which in itself is a
miracle. The only issue is the dead CMOS battery, but I can live with
that.


I've tried again and again to get the 1530 to do something, but it
seems more or less inert. The status lights above the keyboard and the
floppy drive light do flash momentarily if you turn it on, but only if
the display is unplugged. Right now I'm saving it for parts, assuming
that the gas-plasma display, case, and floppy drive will work in one
of my other machines.

I'd like to find a working 1530, to get more performance than the 1520
but keep the orange gas-plasma screen. I have a 1550SX but that wimpy
LCD is not very impressive.

Yes, you can the SIPPs from the 1530 and put them in
the 1520.
Yes, it is impressive that the disk drive is still
working.
The best thing I liked about the 1550 is the mouse
control on the keyboard.
I thought it was cool.

Hi All.
I have just managed to buy 20x ConnerHDDs (20Mb) at a site
mothballing auction, all brand new, sealed and in boxes. These are
all over ten years old and have been sat in these stores for this
time.
I am the proud owner of 4x 1520s and 1x GridPad, which used the same
drive. I will be replaceing the first drive over the weekend and if
all goes well, I will be letting 10 of the drives go.
I paid Ł3 each (yes, thats all!) and that is all I would expect for
them as I know how long I have been waiting for one of these to
appear. I will be selling them on ebay at a buy it now price of Ł3 +
carriage and will be posting on this board the time and date of when
these items will go up on ebay two days in advance for you all to get
a fair chance of getting one.

Regards,

Dave

Dave,
Sounds really good.  I am curious to know if the
drives work after all of this time or if the head has
becomes stuck to the platter at the Landing Zone (LZ).
Please let us know how your efforts go this weekend.
Thank you,

That problem (stiction) can generally be fixed just by
holding the drive in one hand and giving it a quick
twist roughly about the axis of rotation.

Yes, IBM had the same issue once.  But the problem tends to be worse
if they
have sat a long time.  The more often the drive is used, the less
likely it is
to be a problem.  And usually, the twist trick does the trick, at
least in
every drive I've seen with the stiction problem.

Yahoo! Message number: 1290

From: Charles Ford
Subject: Re: [RuGRiD-Laptop] Re: 1520 flash issues

These Conner models pre-date Seagate ownership of Conner.
A hard drive (all of them) are a dry system.  The only "Lube" is in the
ball barring races, two on the spindal, two on the head positioner. 

"Stiction"  Rotational Latentcy  Is caused by one of several problems. 

1 Magnetic lock >  The head setels on the landingzone and is exposed to
magnetic changes over time.  (low level) and magnetically bonds to the
surface.  A quick twist will fix this

2 Galvonic bonding >  Although the drive is filled with dry nitrogen at
the factory it is vented (through a filter) and adsorbtion of moisture is
unavoidable durring use.  Time and temperature changes cause the drive
head to chemically stick to the plater.  A quick twist will fix this.

3 enviornmental goo >  With use a drive will begin to build up a goo film
from smoke (especially cigarette smoke), airborne organtic mater, and
moisture. A quick twist might fix this and if so only long enough to
recover your data. The next time the drive sits overnight it will stick
again.

4 Capacitor ESR increase > ESR is the internal resistanc of a capacitor,
and typically increases with use in the Tantilum devices that are used on
the 30 series conner drives. This increase in capacitor resistance causes
a loss in avaliable torque to the motor.   This can mimic the
enviornmental goo problem. but can be fixed by replacing the caps in the
motor drive circuit (need the big FETs). 
 
A new factory sealed drive will have none of these problems as they are
baged with dry nitrogen. They ALL are found ONLY in used drives. et, al,
It is impossible to tell a new drive from a used one that has been
properly cleaned up. et, al, Many  of us are very good at duplicating the
factory seals.

Yes, IBM had the same issue once.  But the problem tends to be worse  
if they
have sat a long time.  The more often the drive is used, the less  
likely it is
to be a problem.  And usually, the twist trick does the trick, at  
least in
every drive I've seen with the stiction problem.

Hi All;

   I recently accquired a grid 1680  and I dont know any specs on it.
I had a large 2 gig laptop hd laying  around and of course it
recognised the hd as 50 mb anyway the display is good but I think this
just a dos machine , because the screen is not color is this right ???
But it does have a mini mouse at the top

                                          thanks

1520 will run it. Also need to find out if the grid
supports a printer.

Hello synweed and welcome to the group.

Yes, a 1520 will run just about any flavor of MS-DOS. 
I've run 3.2, 5.0, 6.0 and 6.22.

Is your hard drive still working on your 1520 or do
you have to boot from floppy?

From: Shawnerz
Subject: Good Deal On Ebay?

Hey all,
I'm proud to announce that I was the winner of a 100
MHz, 16 input logic analyzer.  I think I got it for a
steal at $150.

Here's the link on ebay:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=7583019765&rd=1&sspagename=STRK%3AMEWA%3AIT&rd=1

I hope the link works.  Anyway, I plan to use it in
debugging and hacking the hard drive/BIOS
communication.  

My initial idea to get around the hard drive
limitation is a "man-in-the-middle" approach.  I
thought about running the IDE lines though a tri-state
latch controlled by a PIC or ASIC of some sort.  On
power-up, the ASIC would tri-state the lines going to
hard drive and respond to the BIOS that a CP322 was
connected.  After that piece of information was
passed, then the ASIC would tri-state the IDE lines
coming to it and enable normal communication to the
hard drive.

I don't know if it will work, but I'll see what info I
get from the logic analyzer and take it from there.

Gridcase Group: Thanks in advance for your help!

I have a Gridcase 1520 (80283) that years ago I connected to my home-built telescope to have it point at varous celestial objects.  Having found new interests, my 'scope has gone unused for about three years.  I hauled it out this weekend, only to find that the laptop exhibits the following message on power-up, after the memory check:

    "Invalid configuration information; error code 2
       Strike the F1 key to continue"

and after doing so,

    "Disk  boot error
      Disk boot error....."

I googled a lot last night, finding suggestions that ctrl-alt-del might work (it doesn't), or "gently" beating on the Connor disk drive (no change).  Most promising was the idea that a 3.6-volt lithium clock battery may have failed.  I tore the 1520 apart, down to removing the mother board to look inderneath it, disassembling the rear connector board, and even got into the electronics inside the display lid, but found nothing that looked at all like a miniature battery with axial leads soldered onto anything.  I feel that if I had a boot disk (long since lost), I could at least get the thing to do something.

Any suggestions?

Thanks again,

I found the pdf file about the Dallas chip just above the dos33.exe file you told me about. BTW, I just managed to boot up with the just-made boot disk.  No C: drive, but when I open B: drive there is operating files there.  Is the B: drive an e-prom?

From: Shawnerz
Subject: Re: [RuGRiD-Laptop] Re: New member, old problem

Ron,
The root problem (sorry for any confusion with
Linux/Unix users) is the hard drive seems to have
failed.
We had a recent post by a former Seagate (?)
(ex-Connor Periphials - [I can't spell]) technician
that basically outlined the three common HD failures. 
I seem to remember that the easiest fix to fix two of
the problems was to twist the drive.
If I remember correctly, the most common problems have
to do with the head sticking either to the platter. 
I'm now HD expert so I may be wrong.
One problem with the 1520 is the BIOS will only allow
the computer to boot from 3 Coonr hard drive models. 
There are 2, 20 MB drives and one 40 MB drive. 

I am trying to figure out a way around the limitation.
 But, don't expect a breakthrough any time soon.  This
modification, if successful, has a stetep learning
curve for me.

Anyway, good luck in getting your GRID back up.

-Shawn

My 1520 is back among the living.  You were right, Dave - the problem
was the Dallas chip.  It booted up fine, with no password or date
setting problems.  Maxim was great about sending me a new chip - their
web site said that delivery would be two weeks, but they ask for a
ship date as a part of the ordering process, so I gave them two days,
not weeks, and that's when it shipped.

I've been occupied with the effort of restoring heat to my workshop.
All of my toys are either in the shop, where it's been too cold to
work, or in my lab, which I don't have easy access to because I
have to pass through my housemate's bedroom (once and future sewing
room of my wife) to get to it.  :(

Subject: Grid 1520 Password

Hello All.

I have been using a Gridcase 1520 laptop for several years now and
have been quite happy. Recently though, the old CMOS battery has been 
giving up the ghost.

So, I purchased a new DALLAS cmos battery, and went to the task of
completely disassembling the unit, and replacing the battery.

After I got the laptop all put back together, and turned it on, I was
greeted by a date on my screen of "55/::/55" and the computer saying
that I needed to set the correct date and time, then asking me for a
password.

I wasnt ready for that password thing and started doing some
googling. What I've found on the web is that after the battery was
changed, since it had no data or time in it, the bios went into
protected mode.  There used to be this program that the Grid
manufacturer ran called "password of the day".  You gave them the
date on your screen, (in my case "55/::/55") and they would punch
that into the their program, and it would return the needed password
to unlock the computer.

So,.......

Does anyone out there still have access to the "password of the day"
program that can help me unlock my Grid 1520?

It's been a really rugged machine and I'd really hate to junk it over
a password.

Does anyone know if there is a work around for the password ??

Any help is appreciated in advance.

Bill

The cmos battery is the small black box underneath the keyboard with
the word "DALLAS" on it.  A real pain to change out. I just did mine.

Having found new interests, my 'scope has gone unused for about three
years.  I hauled it out this weekend, only to find that the laptop
exhibits the following message on power-up, after the memory check:

clock battery may have failed.  I tore the 1520 apart, down to
removing the mother board to look inderneath it, disassembling the
rear connector board, and even got into the electronics inside the
display lid, but found nothing that looked at all like a miniature
battery with axial leads soldered onto anything.  I feel that if I
had a boot disk (long since lost), I could at least get the thing to
do something.

 I don't know yet about the newer replacement Dallas
chip but I used the "grounding" method to get rid of
that problem. It is in the files archive and also was
on the Dalllas documentation. I was under the
impression that it zapped the Dallas battery Bios and
then either the 1520 setup program or internal
workings entered the proper specs. Seems strange that
the chip wouldn't have become grounded when you
soldered it in. Perhaps when you install the virgin
dallas it has to be part of the circuit before it can
receive the necessary info from ROM.

 As you know it's a P.I.A. to access the chip. I can't
guaranty it would work but since I also have to
replace
the Dallas on my 2 1520s I'll be following your
progress with interest. Good luck.

 BTW any info on the Conner HDs someone had discovered
a stash of ?

Well, I can't ground the pins, as my chip appears to not have a pin
#21.

It has a pin #12, but no #21.

Looking at the pin layout chart, #21 is the reset. So, one wonders if
DALLAS has removed the pin to prevent anyone circumventing the
password ?

I emailed PHOENIX directly, who said to contact GRID, as GRID must
have modified the BIOS to do that after the BIOS was made.

So, still have a nice metal boat anchor and no password of the day :(

Bummer. What a catch 22. I recall that there were
several models of that chip. Perhaps you have the
wrong replacement model. At one time customers could
get a code by phone to do the reset. I wonder if the
former Grid employees mail-list who contacted us a few
years ago are still in existence and might know that
code.

Several list members replaced the Dallas chip recently
and reported no problem. This is of importance to me
because I have to replace Dallas chips myself and is
crucial to all of us who want to keep our old Grids
functional. Perhaps a perusal of the Dallas site might
verify if the chip with the reset is no longer
available. Otherwise that would mean finding suppliers
with old stock. Please let us know.

Cannot be too definate about smithereeens. Its an ancient  way of describing 
small particles which are dispersed by a blacksmith with mighty blows of the 
hammer to the far corners of the earth, Not exactly  how modern science 
would define splitting the atom. Anyway its a long way that they send you.

I know that they video most of these types of presentations at CHM.  I don't see a mention
of them being available on the web site, streaming or otherwise.  There is a Feedback link
on the CHM site so you may want to make the suggestion.  I expect you're not alone for
this and other presentations.

From: Shawnerz
Subject: 1520 Question(s) for Monty

Monty,
What can you tell us about the 1520?  
I have 4 of them.  The goal is to try to get the 1520
to boot from hard drive *other than* the 3 that are
listed in the BIOS.

This has been an on-again/off-again project for the
last 4 or so years.

I just bought a logic analyzer and manual (HP1650A) in
hopes of monitiring the traffic between the IDE board
and motherboard as well as the BIOS EPROMs.

Do you have any other ideas or suggestions?

-Shawn

From: Lawrence Walker
Subject: Re: [RuGRiD-Laptop] Digest Number 505

 Could I make a request that members edit their posts
of the dross before they send. It really clutters up
the messages (especially in the digest), when you
include posts from 4 generations back, including all
the stuff that Yahoo adds to each post.

 I purposefully left all the crap here as an example.
I must admit I have also been sometimes guilty of this
but it really is just an unneeded and lazy habit.

Hello all...
I just lucked into a 1520 5 hours ago (this box is wild!), but when I
attempt to boot from AC power, I get a heavy clicking sound and a
flashing lower disk light.  I also noticed what appeared to be a RAM
slot by the top left of the keyboard, but it's empty.

can anyone help me?  I'm sooo lost here.

Hey there, "Dick"! ;-)
You said you're booting from AC power.  Is the power
supply the external type that supplys power to the
1520 via the barrel connector, or is it the type that
slides into the battery compartment?
The reason I ask is you may want to take a voltmeter
(or multimeter), if you have one, and make sure the
supply is putting out 16 volts.
It has to be able to supply an initial surge of about
2.5 amps to get the 1520 started.  Once the HD spins
up, the current levels out at about 1 amp.

The hard drive disc may be stuck to the head.  That
also may be causing the clicking noise you're hearing.

Let us know how things are.

I think if you hit the "f" key right after the beep it will be consistant.

From: Lawrence Walker
Subject: Grid 15xx FAQ

 Was there ever a FAQ for the Grid 15xx ? If not it
would be a great project to have for Grid diehards.
No I'm not volunteering, my plate is much too full at
the moment, but possibly a distillation of the message
list could ease the project if everyone took part.

 What initiated this thought was sorting thru the
message list trying to find the oft-repeated model #s
of the Conner drives that work with the 15xx BIOS.
CP3022, CP3044 and the CP3104. Right ?

 I'm going to do a wanted appeal in various old
computer forums. Who knows I could find some. Or even
a motherlode of stored Conner HDs. Worth a try. These
are designated 1/2 height aren't they ? Just to have
my terms correct. Also anyone know what other L-Ts
used these drives ?

 It has been for a long time that the group has
searched for a solution to the limits of the Conner
drives with numerous ideas, but no solutions. For now
I'll go for the external solutions, just using the
internal HDD as a boot vehicle. I luckily have the
SCSI pod and will also try using external SCSI
devices, parallel port devices etc. For the most part
you don't need all that power when you're away from
home. The I-net is the main cropper.

 I presently have a PP Microsolutions Backpack CD with
an internal ESS sound card and a PP Zip disk as well
as a SCSI Syquest Zip. The Delorme serial Earthlink
GPS is small and doesn't take power from it's host. I
have about 3 dead battery pods but I think they are
easily hacked with replacement batteries. Perhaps
Nickel-Metal Hydides. And of course there's the common
Cigarette lighter adapter for cars. I also have a
commonly used with some outside tools such as a
weed-eater 12v rechargeable battery pack. I haven't
tried these yet on my 1520s(dead RT chip and Conner
HD) and there might be some problems if the PP isn't
2-way, but do use them on my Dauphin DTR-1.

 Sure it isn't an elegant solution, but the 15xx are
not something you can slip into your pocket anyways,
and their ruggedness, the ability to take 8 megs of
ram, and the red plasma display, enhance their "Cool
Factor" and satisfy your geek yearnings.

All,
A new user from the UK joined the group.

Here's his info:

I think your name is Dave.  I may be wrong in that. 
Apologies if I am.
I really should write this down and start a FAQ.  If I
remember correctly, code 02 is the CMOS battery.
I believe there is a copy of MDDOS 3.3 in the Files
section of the group.  It will unzip to a boot disk.
Unzip the file to a floppy and put the floppy into
your Grid.
Leave the computer powered up for about 20 minutes, 
then re-boot (the 20 minutes may give the battery
enough of a charge to hold it for few seconds during
the reboot).  It *may* boot from the floppy.

Let us know if that works.  We can take some steps
from there.

-Shawn

 Hi Evan. Welcome aboard. It seems we have several
groups in common, including VCF where my moniker is
Micom 2000. There hasn't been too much activity
lately. It goes in fits and starts as a perusal of the
archives will show. The 2 most discussed topics are
figuring methods to replace the small Conner drives
which have a high incident of failure(due to age
?),and replacing the Dallas battery/RTC on these
otherwise nearly indestuctable beasts.  There is a
wealth of info in the archives.

Hello there.  My name is Shawn.
Sorry I haven't responded sooner.  Camping with the
family this weekend. :)
The problem is it didn't work.  I don't know why.  I
made some minor changes to the info the in the BIOS
chips and the computer never booted.  There are a lot
of things that I do not know.  I'll try to list my
questions below:
The BIOS has "plain text" enteries for the 3 hard
drive models.  I expected to find matching Cylinder,
Head and Sector (CHS) values somewhere in the BIOS.  I
couldn't find them.  

In Charlie's program for the 1535 BIOS, you have to
enter the CHS values and the program makes changes in
the appropriate places.

I never really knew what the drive actually reports as
its model type.  Does the drive return a long string
and the BIOS parse that string and look for the
appropiate model type?  

I bought a logic analyzer over the winter.  I haven't
had the time and motivation to monitor the
communication.

I guess that's about it.  I just haven't had the time
to play with this.

Thanks,
-Shawn

From: Michael Brutman
Subject: Re: [RuGRiD-Laptop] Re: Grid Bios.

Charles Ford has a working technique.  According to post 217, he did the 
patch on a 1530.  Why doesn't this technique work on the other models?  
I wouldn't expect that the program to work against a slightly different 
BIOS, but the technique is the same.

On a true PC AT you would have 47 different drive types defined by a 
table in ROM, which sucks if you have a drive that doesn't match.  On 
this Grid the level of suckage is even higher because there are only 
three drive times.  And from what I'm reading, it is trying to 
autodetect the drive so that you can't force it.

On a clone BIOS you would be allowed to define the specs for two 
drives.  The clone BIOS would store those parameters in the CMOS memory.

Either way, by the time the boot process starts, INT 41h points at the 
drive configuration table entry for drive C.  If it was user defined, 
the clone BIOS found a place in RAM to tuck the specs away.  If it was a 
predefined type, INT 41h points somewhere into the table.

On my 386 clone I'm using a Promise card that auto-detects the drives, 
so there never is a built-in drive table.  It's got some RAM onboard I 
presume and it puts a drive parameter entry in that RAM each time at 
bootup.  I was able to use debug to examine it, and sure enough, it 
makes sense.

Based on my incomplete knowledge of these things, I'd try this:

- Patch the BIOS so that it doesn't try to autodetect the drive type.
- Instead, set INT 41H to a known location that has the right drive 
parameter table entry.
- Use one of the ROM program lots to put an extra BIOS chip in the 
machine that has the drive parameter table entry for the drive you are 
using.

I've not disassembled the BIOS yet, so I don't know how 'important' the 
drive type is to the system.  I suspect that they just were 
interrogating the drive for a name and setting INT 41h, instead of 
making users go through the CMOS setup.  If that's the case, clipping 
the code that does the interrogation is easy.  Heck, you might even be 
able to drop the drive parameter table entry right where the code used 
to be, avoiding the need for one of the ROM slots to be used.

The Connor drives might have been providing their geometry to the 
machine, which is why you can't find it in the BIOS.

I don't think a logic analyzer is going to help ...  This needs a good 
disassembler.

Subject: Re: [RuGRiD-Laptop] Re: Grid Bios.

Ok.  Here are the real problems. 

1) Even though you can use any size hard drive on the 1530 A patch for 
the 1520 still does not exist. 

2) The drive has to have the exact interface footprint in order to plug 
into the drive backplane inside the 15XX.  This limits the available 
equipment to a hap-hazard group of drives that by chance happen to fit.

3) Any size hard drive does not currently include compact flash, which 
many of us would like to use.

I think that is about all of it.  We are all aware that there is a 16 X 
1024 X63 geometry limit on the drive.
DOS 6 is able to address 2.1G of hard drive space in a single partition 
and there is no hardware reason for the geometry limit.

The ATA table contains the actual geometry as well as the drive model 
number.  So ??  why limit the system to a small group of model numbers.  
An ATA table based boot patch would allow us to use a much larger verity 
of equipment.

There is no system on the market today that is as stable or as ruggid as 
these old GRiDs
I have even been running Linux on one of them

I would have done the same for the 1520, but I don't have one to tink on.
Currently I have returned to school and have precious little time to hack
BIOS.  I got the method from a post on Rob's GRiD board.

I do however expect to learn enough about the BIOS to Boot loader transfer
to pull off an ATA boot patch (probably within the next year and a half)

I'd like to jump in.

Mike: I read your previous posts.  Can you suggest a
good disassembler?  I have a hex editor, but, as you
can probably guess, that doesn't tell you much.

Also, will the disassembler tell you when interrupt 41
is written triggered?
My knowledge of assembly is *very* small.  However,
from what I know, once an interrupt, any inturrept, is
triggered, the program is supposed to enter an
Interrupt Service Routine (or ISR) to figure out what
interrupt was triggered and what to do about it.
So, what does INT 41h control?  Would the disassembler
be able to tell what the CPU is supposed to do when
INT 41h is triggered?

As far as physical limitations, I'm pretty sure just
about any 3.5 in' drive will fit in the 1520.

Thanks for your participation, Mike.

Subject: Re: [RuGRiD-Laptop] Re: Grid Bios.

Unfortunately, I'm using debug.  I need to find a better disassembler, but don't have the time to
go cruising around testing them.  Debug is good enough for now.

I never use debug to actually debug BIOS code - you can't really.  I just use it to examine the
code, and play 'computer' in my head.

Interrupt vectors on a an x86 machine are kind of misnamed/misused.  We all know what an interrupt
is from classic computer science.  An interrupt vector should point at the code to run when an
interrupt is taken.  x86 machines misuse interrupt vectors occasionally though.  Instead of
pointing at code to run, sometimes they point at raw data.  In the case of INT 41h, the interrupt
vector (at memory location 0000:0104) points the the drive parameters for the first hard disk. 
Nothing ever causes an interrupt 41h because if it, it would jump to whatever that location points
at and try to execute data.  And boy, that's fun when that happens ..  Other interrupt vectors,
like 13h, 20h, etc. point at real code to execute, as they should.

I believe that one of the purposes of the BIOS init code is to setup the pointer at INT 41h so
that it points at the correct drive parameter table to use.  Once that is set the BIOS can boot
off of it.  I need to check a machine without a disk to see what it gets set to ...

True.  The compact flash interface has an IDE / ATA mode that looks much 
like an IDE drive
I tried one using my 1530 patch and could not get it to boot.  I don't 
know why
The adapter works just dandy in other systems.

From: Stefan Otto
Subject: RE: [RuGRiD-Laptop] Hello world!

Hi Shawn,
I've been around for some time (just lurking however).

Back at school I did some Z80 and 6510 assembler
programming (games mostly). My renewed interest in
computers from that time actually came from a
differend hobby: movies. I'm a big Aliens fan and when
I noticed the Compass being used in the movie I had to
get one.
While on the hunt for the correct Compass I noticed
what an truely innovative machine this was at it's
time. Til now I got an 1131 and a 1137 (still looking
for an 1139 - what's the difference to the 1131 by the
way?) and I'm trying to recreate the display seen in
the movie. Sadly, there's almost nothing except for
the most basic infos (like CPU - which is an 8086 -
and memory size) about these on the net (and this
refers mostly to the 1101). Especially a memory map
and a description of the graphics chip would be great.

Cheers,
Stefan
  


---------------------------------
Hello there Stefan and welcome to the group.
If I'm not mistaken, the Compass is built around an
8088 processor.  You may want to search the web and
see if any antique computer sites have any programs
for the 8088.
Good luck,
-Shawn

I don't even have a memory map for the 1520's that I

You would still have to write your programs externally and port them

 Mike Bruitman I believe is probing the Grid 1520
Bios.
If he should come up with a BIOS fix are there any of
the list members who have an EPROM burner and would be
willing to burn chips for the list ? I'm not talking
about a free ride and personally would be more than
willing to pay for new 1520 BIOS chips. Or any
suggestions of how to obtain reprogrammed Bios chips,
when such a fix is documented.

 Perhaps other members who have more skill than I
might re-examine the BIOS dump based on Mike's
suggested areas of possible problems and come up with
something since we are the most familiar with the
GRID.

My 1131 is running GRiD-OS while the 1137 uses MS-DOS
2.1 or 2.2 (I'm not sure which one).
So what is QB11 or QB45?
Getting programs on and off won't be a problem as I
have a 5-1/4" disk drive for my PC and for the GRiD.

Cheers,
Stefan

Depending on the supply of chips and since I don't have a 1520 to test on I could do
some up unless its a bastard type chip.

Lawrence,

I'll probably buy an old EPROM burner when the time times - I need it
for similar projects on other machines anyway.  I won't unleash my
fury on the world unless it works. ;-)

In my previous notes I laid out how the hard disk setup code on clone
is supposed to work, and verified it against my 386 machine.  I'm
assuming that the GRID BIOS just tried to make things simpler by
probing the hard disk.  If it got its values from the hard disk then
it would use one of three table entries in ROM, or it would write the
values it got from the hard disk into RAM somewhere.

Just for grins, would somebody with a working 1520 boot DOS up and
tell me the results of the following:

debug
-d 0000:0104
0000:0100              FF 03 0C 02-6B 09 0C 02 BC A6 00 C0
....k.......

Just the first four pairs of digits are enough.  That will tell me if
it's using a table entry in ROM or RAM.

From: "mbbrutman"
Subject: Re: Digest Number 523

BTW, the code that sets INT 41h and INT46h is around offset 1717h in
the merged 1520 BIOS dump:

ES:
MOV     BYTE PTR [0077],00
MOV     [0104],SI
MOV     AL,BH
AND     AL,0F
MOV     AH,9A
CALL    1741
JZ      1835
MOV     [0118],SI


The 3rd line shows the setting of INT 41h (memory location 0000:0104)
and the last line shows the setting of INT 46h (memory location
0000:0118).

Kind of curious that it might actually set INT 46h ...  that implies
that it has at least partial support for a second hard disk.

Now the trick is to figure out what sequence of steps got it to this code.

First, QB11 and QB45, (I believe) mean Quick Basic
1.1.

Second, I have an EPROM burner, eraser, and 4 or 5
sets of EPROMs.
I had dumped the Grid contents and made a minor change
to the Phoenix BIOS text message.  I saved the
changes, updated the checksum and burned the EPROMs. I
put them into my 1520 and it did not boot with the
modified EPROMs.  I didn't go any further with any
testing.  If we get something that may work, I'll be
more than happy to do more tests.

As far as Mike's debug commands, I'll enter it in
tonight and see what happens.  It will give me

does it before I do.

Mike: how does one get the point to be able to suggest
what to do?  In other words, how are you able to take
hex values and convert them to assembly?
You had made a mention a while back about CS101.  I've
never taken a Computer Science course.  Pretty much
all of the info I have on my Grids has come from
hacking around.  So, any help would be appreciated.

I'm using debug, which is good enough for now.  The big problem with
debug is that when you look at a dumped BIOS it offsets everything by
0100h, because it expects to work with a problem.  I can fix that
deficiency if I look around for another tool.  In debug the 'u'
command unassembles code.

In my previous msg I posted where I think the interrupt vectors are
being set.  I have to work backwards through the code now to find
where it does the string comparison looking for the three Connor
drives.  If I find that, I think the rest is easy.  Unfortunately,
it's a lot easier to go forward looking at what happens down the road
from a known point than it is to find what got you there in the first
place.  So finding the code that got it to that point is just going to
be trial and error, or pure luck.

Just tried the old "Hello World!" in QB45 and it
worked even in a loop (ok not on the GRiD yet but it's

compile with the lower DOS compatibility? (I have to

OK, I'm a few days late.  But, I have results.
Mike, you asked for just the four pairs of digits.  If
I'm reading things correctly, nothing was returned. 
The output looked like this:

0000:0100          
            6D C6 00 F0-6D C6 00 F0 6D C6 00 F0
0000:0110 
6D C6 00 F0 6D C6 00 F0-6D C6 00 F0 6D C6 00 F0
0000:0120
6D C6 00 F0 6D C6 00 F0-6D C6 00 F0 6D C6 00 F0
  .
  .
  .
0000:0180
00 00 00 00

As you can probably guess, the patter repeated from
0100 to 0170.  The dump ended at 0180 with the 00's. 
I added the carraige returns so I could fit the text
on the page.

My guess is you only needed the first 4 bytes but I
gave you everything.

Subject: Re: Digest Number 523
text/plain; charset="iso-8859-1"

Hmm...  Crapola!

The address that it is set to is F000:C66D, which is outside the address
area of the 32K ROM.  So now I'm confused ..  unless there is RAM up
there, my theory is shot.

Try this:

   d f000:c66d

And send me back the first 5 or 8 pairs of bytes.

The next trick is to figure out if it is ram.  This part is tricky.
We're going to use the 'e' command in debug to change one byte, then the
'd' command to see if the change stuck.  To prevent damaging anything
good, don't have anything loaded except pure DOS and reboot immediately
after you do it:

Here is my example:

-e f000:c66d
F000:C66D  00.AA
-d f000:c66d
F000:C660                                         00 00 00

(Yes, the spacing is a problem)

In this example, I entered 'e f000:c66d'.  It responded with 'F000:C66D
00.'  I entered 'AA' after that.  (You can use anything you want - just
make sure it is different than what is there.)  The I did the 'd
f000:c66d' to display the value.  Note that even though I told it to
change 00 to AA it didn't, which means that the address on my machine is
a ROM chip.  If it *does* change on your machine, then you've got RAM at
that address which would be a good thing.

Subject: Re: [RuGRiD-Laptop] Re: Digest Number 523

Mike,
My guess is this is ROM.  The reason I say this is
because, in debug, the right side shows the ASCII
conversion of the data.  I see error messages.  For
example, starting at F000:C6B0 I see:
"Type (R)eboot, other keys to continue"

To answer your questions:

OK, here are the 8 bytes from C66D to C674:
50 1E 52 B8 0B FF BA 20

I did your suggested test, and the jury says, "IT's
ROM!!"
I changed address -6D from "50" to "AA."  I read it
back and it remained "50."

BTW, I'm using MS-DOS 3.3 booted from a floppy.  The
HD has been removed.

Mike,
In playing around, I found that RAM seems to be
starting at 0000:0000 and ends at 9FFF:000F.
Does that help at all.
BTW, I don't know if this makes a difference, but I'm

First, don't risk frying a good hard drive.  Anybody else can try this
at home too - it's a pretty harmless experiment.

Second ..  if you do try it, I suspect the results will be quite a bit
different.  I'm hoping that 0000:0104 does point into RAM or ROM, and
that whatever is at that address looks like an entry in a hard drive
table.

I still think that adding ATA boot capability is the

patch in a 55AA signeture, read the ATA table and dump
the info into the boot DCT.

I don't think the patch will tak much, it is locating
the damn DCT to update the table that bugs me.

Allong the lines of using a drive ID hack. You can do
this if you create a boot partision of exactly the
same size (sector count) as the 3044 or other
approperate drive. Then load a DDO to create the
second partision using the nest 2G of sectors. Then
just change the drive name in the table.

It's just like any other clone in that respect ..  there are reserved
areas in the memory map for BIOS extensions.  When a SCSI BIOS is in
use it takes the responsibility for setting INT 41h to the current
hard disk.  It also provides updated BIOS routines for talking to the
SCSI disk.

Another interesting card from the past was made by Promise.  It didn't
have an IDE controller on it, but it did have an upgraded ROM on it
that would drive the IDE controller in your system.  It was sold to
upgrade machines to allow them to use larger IDE disks back when
motherboard BIOSes were not easily upgradeable.

The same type of EPROM could be installed in a GRID ...

Lawrence - you should do the same experiment on your SCSI enabled Grid
- the results would be interesting as well.  If debug scares anybody
I'll write a little DOS exe program to do the dirty work.

Subject: Hard Drive Update

All,
OK, here's the latest.  I'll provide all of the gory
details even though they're not relevant.  BTW, I did
this all at work yesterday.  Good thing my boss was
out! ;-)

I found my old Conner HD.  I gave it a couple twists
and powered it up without the IDE connected.  It spun
up just fine. 
I put it into the 1520 and the 1520 never saw it.  By
"saw" I mean fdisk returned an error saying there were
no Hard Disks in the system and none of the HARDDRIVE=
parameters worked in conf1520.exe.

I took it out and attached it to my WIN XP computer
via USB.  The USB hardware device thingy in the system
tray saw it, but Windows couldn't mount it.  I
expected this since WIN XP doesn't support FAT16.

I managed to find at WIN98 machine and I put it into
it.  It mounted it but it was totally corrupt.  The
label had something like "yt\Ftcon."

I tried to format it in Windows and it said it
couldn't.

I opened a DOS Window and tried fdisk.  Fdisk probably
would have let me do it but when you tell fdisk to
delete a partition, you have to enter the label of the
harddrive.  fdisk won't allow you to enter lower case
numbers nor special characters.  fdisk was out.

I looked on the Internet for low level formaters.  I
found at site that had a 1993 copy of Disk Manager by
Ontrack Computer Systems.
I booted the Grid into DOS 5.0 and ran Disk Manager. 
I recognized the drive and did a low level format.  It
took about 2 hours and it found numerous bad sectors,
but it did it.

I rebooted the Grid and it still didn't reconize the
drive.  I ran out of time to do anything else.  If I
get time this wekeend, I'll post my results.
I imagine that I'll have to do a fdisk and (high
level) format in another machine.

That's it for now,

Mike,
I'm not ready to write the Connor off just yet.  I
don't remember where that drive came from.  It may
have been corrupt when I got it and I never got around
to try to fix it.

I was in a rush when I sent that email.  I remembered
later that there were two more things I wanted to add.

The USB icon in the system tray in WINXP reported the
drive as a "Conner P eriphieral"
I don't know if it's significant or now, but I thought
it was odd that there was an extra space in the 9th
position.  The first 8 letters were correct.
The BIOS on the WIN98 machine identified the drive
perfectly as a Connor Periphieral CP344.

The other thing was many moons ago, I kinda remember
somebody mentioning that on the XT and early AT
clones, you had to issue a debug command to low level
format virgin drives.
Is that true?  Does anyone remember having to do that
or was that something unique to some obscure OS?

Thanks,
-Shawn

It's just like any other clone in that respect .. 
there are reserved
areas in the memory map for BIOS extensions.  When a
SCSI BIOS is in
use it takes the responsibility for setting INT 41h to
the current
hard disk.  It also provides updated BIOS routines for
talking to the
SCSI disk.

Another interesting card from the past was made by
Promise.  It didn't
have an IDE controller on it, but it did have an
upgraded ROM on it
that would drive the IDE controller in your system. 
It was sold to
upgrade machines to allow them to use larger IDE disks
back when
motherboard BIOSes were not easily upgradeable.

The same type of EPROM could be installed in a GRID
...

Lawrence - you should do the same experiment on your
SCSI enabled Grid
- the results would be interesting as well.  If debug

I'll write a little DOS exe program to do the dirty
work.

Man, I screwed the pooch on this one.
(translation for all you non-Americians: "I made a
big, dumb, mistake.")

I played around several more times with Disk Manager
(DM).  I partitioned the drive, formatted the drive
(in DM), but fdisk and the GRID would not see it.

I thought it was odd that DM could write to perfectly
but the 1520 could not.

I loaded the BIOS EPROM data on my Windows machine and
the answer jumped out at me.  The drive I've been
trying to work with is a Connor CP3044.  The three
models the BIOS supports are the CP3022, CP344, and
the CP3104.  DOH!

The CP3044 probably came from my old 1550SX machines
before I got rid of them.  That would explain why I
found the hard drive on a shelf and it wasn't
installed into one of my 1520's.

Question for Mike (when you return from your trip), or
anyone else: why was the Disk Manager program, running
on the 1520, able to "see" the CP3044 drive, partition
the drive, and format the drive, while BIOS and fdisk
could not "see" it?

Subject: Computer Science 201

All,
I'm hoping the community can explain a concept to me. 
Charles, you alluded to this concept a while back.  I
didn't understand it then, and I still don't.
This has to do with disk overlays and stuff like that.

I understand that a computer has a BIOS.  You turn on
the computer.  A program goes out and scan the buses,
determines what devices are out there.  I also
understand that the BIOS set up address ranges and
interrupts.  So basically, if a device is on a bus
(like a disk drive) the BIOS knows it's there and
reserves an address range and interrupt for it.

Then, the Operating System (OS) boots.  Among many
other things, it queries the BIOS to see what devices
are on the bus(es).  The OS also gets (or knows from
the device driver) the address range and interrupt
information.

Then, you have an Application (or Program).  In crude
terms, the Application tells the OS, "Here's some data
for this device."  It's the OS's job to get the data
to the device.

In short, as I understand it, an Application can't do
things outside of OS.  Excluding DMA transfers (which
are a separate case), the Application can't talk
directly to the hardware without going through the OS.
 If so, you get segmentation faults, application
errors, lock-ups, and the like.

In short, as I understand it, the application is
constrainted (or limited) by the OS.  And, the OS is
contrained (or limited) by the BIOS.

Having said that, how was the Disk Manager program
running on the 1520, able to format my CP3044 disk
drive, when the GRID BIOS didn't support it, MS-DOS
fdisk couldn't "see" it, and I couldn't get to it via
the command prompt?

Thanks in advance,
-Shawn

Subject: Re: [RuGRiD-Laptop] Bonehead move

PCs have BIOS and BIOS extensions to handle devices.  Many devices are 'standard', as in they are
located at a known place in memory or they respond to known I/O port addresses.  The BIOS (whether
built in or added on) just makes high level routines for talking to devices available.

You, the application writer, are allowed to talk to a device by altering memory or sending I/O
port commands directly to it.  Nothing will stop you.  It is harder to do, but quite possible, and
desirable in some instances.  For example - if you know you are talking to a CGA adapter, you can
do it much quicker yourself in your own software by playing with the memory at B800:0000 directly,
rathrer than using BIOS routines.  Same thing applies to serial ports, etc.

On a more advanced OS you are not allowed to do that.  Your app talks to the OS, and your OS does
the rest.  In theory, your OS would talk to BIOS to get things done.  In reality, most OSes
provide their own software for talking to devices so that the BIOS is almost never used after a
machine boots up.

Honestly, I don't think that's it.  The CP3044 isn't

Subject: Gettin' beat by the demons of 1980's technology

All,
I took home a Needham EMP-20 EPROM programmer from
work to use over the weekend.  I thought I'd have a
backup to my Quantec (made in Canada, eh) programmer.
The Quantec uses the serial port and the Needham uses
the Parallel port.
I first tried using the Needham.  I dug out my old 386
laptop connected everything up, and then realized the
paralllel port was bad.  I got blown out during a
lightning storm several years ago.  I tried to see if
the software could see the programmer anyway.  It
didn't.

I didn't think it was a big deal because I have the
Quantec.  I connected the Quantec and it would not
power up.  It has no power switch, but when you
connect the power transformer, it won't turn on.  I
pulled it apart and the voltage regulators have volts
present at their input and volts present at their
output, but the unit does not power up. :(
That's how Friday night ended.

Tonight, I thought I'd try the EMP-20 on my Win2K
machine.  I installed the software and rebooted to a
MS-DOS floppy.  MS-DOS 5 won't see my hard drive.  The
DOS boot disk created under Win98 will see my c:
drive, but the EMP20 softwarwe still doesn't see the
programmer.  I changed the BIOS setting on the
parallel port from Normal to EPP to ECP to EPP+ECP
(rebooting each time) an the software still doesn't
see the programmer. :(
Keep in mind I am not operating in a DOS window.  I
have completly rebooted to DOS.

I guess my next step is to trouble shoot the Quantec
to see why it won't turn on.

In case that is the problem.  Also be sure that your cable is good.
It should be a direct parallel (many times problems with a parallel
programmer is simply a serial cable.)

Charles,
Thanks for the tip, but the cable wasn't the problem. 
As it turned out, my 750 MHz Pentium was too fast for
the EMP-20.
I loaded the software onto my P1-166 laptop and
everything the software communicated to the programmer
just fine.
I'm taking things in slow baby steps.  I want to make
sure I can copy with no changes to the EPROM, and make
sure the Grid still boots.
Then, I plan to make a change and see if it boots.
This is all to see if I can get my Grid to support the
CP3044 HD with a "mere" 2 character text entry change.
Since the Disk Manager program was able to access it,
I'm wondering if a text entry is keeping the Grid BIOS
from supporting it.

1520's off and on since Memorial day.  Learned a ton
of stuff and it took a long way to get here, but I'm a
little closer to getting the GRID to boot the way I

As it turns out, GRID put out (at least) two versions
of BIOS for the 1520.  The newer version supports 6
hard drives instead of the 3 hard drives in the older
BIOS.  The newer BIOS automatically supports the
CP3044 hard drive.
I have a 1520 with 1 meg of RAM booting MS-DOS 6.22
from the 3044 HD.

TO answer the ealier debug question, the response to
"0000:0104" is:
"01 E5 00 F0-6D C6 00..."
The "00 F0 6D C6" pattern repeated itself until the
last line.

I ran the hdlook.exe program, redirected the output to
a file, and here are the results:

CMOS bytes:

  Hard disk type 47 RAM area bit is off
Type of fixed drive 0: 15

Subject: EPROM's and checksums

All,
I didn't want to bore everyone with my baby steps of
progress, but I've been working on my GRID's for
while.  I used a couple of IC sockets and 26 guage
wire to extend the eprom location away from the video
card.  It's a long story, but here's my current
roadblock:

BTW, My hex editor is WinHex.  I like it more each
time I use it.

I can copy an eprom, put the copy into the grid, and
it boots.  So, that tells me my equipment and my
process works.

If I make a change to the eprom data, burn a new
eprom, the computer will not boot.

My thought is there is a checksum error.

The 16 bit checksum value is printed on the top of the
eprom.  If I take the eprom data, save it to disk,
then have WinHex compute the checksum, it matches what
is on top of the eprom. *That checksum is not stored
in the eprom data.*

If you merge the odd and even eprom data files, some
interesting things come to light:
o The 16 bit checksum is not stored in the data.

o The newer BIOS is significantly different and uses
more space than the old BIOS.  However, the 8 bit
checksums for both versions computers to "00"

o 00 is the last byte in both BIOS versions.  In fact,
both BIOS versions end with "dd/mm/yy FF FC 00" (where
dd/mm/yy corresponds to the date the BIOS was made).

o When I make my changes, the 8 bit checksum computers
to "04"  When I change the lasy byte to 04, the
computer does not boot.  If I make my changes, and
leave the last byte at 00, the computer still doesn't
boot.

So, is it reasonable to assume the last byte is the
checksum?  If so, why would both BIOS versions
checsums, made 7 months apart, compute to 00?  
Why is it when I make a change, I can't get the
computer to boot?

Charles: on your change to the 1530 BIOS, did you run
into the same problem?  Was there a checksum stored in
the data?  If so, where was it and was it 8 or 16
bits?

Ideas anyone?

And here is the translation:

The pointer to the hard disk table entry for the first hard disk is
F000:E501.  This is what debug told you as well, except that debug
shows you the bytes in 'little endian' order as they appear in memory,
not as they appear in a register.  It is also stored offset first,
then segment ..  so "01 E5 00 F0" -> "F000:E501"

That address is way up there, so it is definitely in the ROM.  It also
correctly shows the size and geometry of the drive.

The second table entry is bogus, and it is set to the the standard
10MB drive.  It would have been ignored at boot time because the CMOS
says the type for Drive 1 (second drive) is zero.


So, to make a long story short.  It is patchable, and the parameter
table for the drives is in ROM.  If you look at the ROM in the area of
those addresses that is probably the start of the drive table.

Funny that it lists the 40MB drive as drive type 15 with an extended
type.  I'd have guess that since it recognizes only 6 types of drives
it would have been 1 - 6.

Mike,
Thanks for the response, but it brings more questions.
The ROM area I'm dealing with is on 2 16K chips. 
Merged togeher it's 32K.  That is only 7FFF in hex.
So how do I find location F000:E501?
I realize the F000 is probably an offset, but what
about the E501?  I don't have that much space.
Then, what am I looking for?  Am I looking for
different combinations of 997, 5, 300, and 17 in hex?
Any ideas or clues how they may have stored that data?
 Like, did they add, say, the 997 and the 5 and store
that value?  Or did they have a separate entry for
each parameter?
I just did a search for the values of 997 and 300 in
hex and nothing look obvious.  For example, the hex
pattern 3E5 didn't appear together.

Subject: 30 pin SIMM's to SIPP's

All,
As I was working with my GRID's the other week, an
idea came to me on how to convert SIMM memory modules
to SIPP to fit in the GRID.
Longtime members (4+ years) may remember I desoldered
several pins from a SIPP module and sent them to
several parts vendors (Digi-Key, Amp, Mouser, and a
couple others).  The ones that responded said they
didn't carry that type of pin.

As I messed around with the EPROM sockets, an idea
came to me to use those pins.
So, let's say you have an old DIP IC socket similar to
this:
http://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?langId=-1&storeId=10001&catalogId=10001&productId=112205

The pins can be removed by pushing them backwards
through the holder.  Then, the pins can be soldered to
old 30 pin SIMM modules to turn them into SIPPs.

Sometimes, I amaze myself. ;-)

Yes, it can be done by inserting new cells into the
harness.  Usually, there is a connection between the
cells.  It all depends on the configuration.
If you send me a snapshop if the cells, I can provide

Subject: 1520 BIOS File Added

All,
I added the merged file of the 1520 BIOS EPROM .  A couple of years
ago, I added a 1520 BIOS file called "1520 BIOS Merged File.txt."  That
appears to be the first version.
The file I just added, "1520 3044 Merged File.txt" is a later version.
I added the 3044 in the title because the BIOS supports the CP3044 hard
drive.
More to follow.

From: Shawnerz
Subject: Help needed: 1520 BIOS file

All,
Here's the short version of the story:
I need somebody with a working 1520 that *does not*
have a CP3044 hard drive to go to
http://www.brutman.com:/hdlook.zip and download the
file. It is 'password
protected', and the password is 'password'.

I need you to run the exe file and post the results.

Now for the long version:
I looked at the merged file with a hex editor
(WinHex).
In this BIOS version, the ASCII text values for the
supported hard drive models are at 0x754C.  The 6
models are the CP3022, CP3024, CP3044, CP3042, CP344,
and the CP3104.

I ran Mike's helpful program to get the drive
information.  
The info from the drive was:
Maximum cylinders: 977
 Maximum heads: 5
 Write precomp cyl: 300
 Control Byte: 0
 Landing zone cyl: 977
 Sectors per track: 17

The mission was to find the drive geometry in the BIOS
file.  977 is an odd number and should stand out.  I
converted it to hex (3D1) and did the little Endian
(sp?) shift so it came out as D1 03.  I searched for
all values of D1.  Since the value 977 appears twice
(Cylinders and Landing Zone), I would expect the
sequence D1 03 to be close together.
I would also expect to find the Sectors (11h), and
Write Precomp (12C, 01 2C converted) to be close by as
well.
Starting at address $64FD, it appears there are
numerous drive table enteries.  (Since the character
sets aren't the same, I can't paste the hex characters
into this email.)

Taking the values from the table above:
Decimal     Hex      Little Endian Conversion 
300         12C      2C 01
977         3D1      D1 03
17          11       11
5           5        05

Then I looked for the above numbers in a series.  And,
I found them.  At address $6501, the sequence is:
D1 03 05 00 00 2C 01 00 00 00 00 00 D1 03 11

The first D1 03 could be the cylinder value.
The 05 could be the heads.
00 00 don't know.
2C 01 could be the Pre-Comp.
00 00 00 00 00 don't know.
2nd D1 03 could be the Landing Zone.
And finally, the 11 could be the Cylinders.

Everything fits perfectly.  Too perfectly.  I looked
on the web for values of the other 5 hard drives.  It
appears that one person has the values and every other
site copied those values.  However, I could get none
of the other drive parameters to match the vaules in
the table.
Looking at the pattern, it looks like there are values
for 18 different drive geometeries.  That could
correspond to 3 different geometries per hard drive
model.  However, nothing matches the drive geometries
on the web.

This is why I'm asking other members of the group with
working 1520's to run Mike's program and post the
results.  I need the info to match the information in
table to the correct drive.

I hope that all makes sense.
Thanks,
-Shawn

that he might have exited the search for a solution to

that he still keeps an eye open on this site.

 He has a full-time job with IBM, a dedication to
expanding the capabilities of the IBMjr and maintains

Subject: Re: [RuGRiD-Laptop] Re: Help needed: 1520 BIOS file

I didn't give up on you guys, and I intended to verify Shawn's walk 
through memory.  But I got sandbagged for 6 hours last night trying to 
diagnose a system problem on my beloved Jr, and I was up waaay to late.  
(It turned out to be user error.)

Shawn,

In memory a drive entry looks like this:

2 max cyls
1 max heads
2 reserved
2 write precomp cyl
1 reserved
1 control byte
3 reserved
2 landing zone cyl
1 sectors per track
1 reserved

The machine is 'little endian', so when you read a 2 byte value the 
bytes will appear in reverse order in memory.  Which is exactly what you 
did, and what the program does for you.

Your string of numbers is interpreted as:

D1 03 max cyls (0x3d1 = 977)
05 max heads (5)
00 00 reserved
2C 01 write precomp cyl (0x012c00 = 300)
00 reserved
00 control byte
00 00 00 reserved
D1 03 landing zone (977 - perfect!)
11 reserved

So yes, you got it right.

These things are organized in a table in memory, so entries for 
successive hard drives will be back-to-back in memory.  If I write some 
more code I might be able to tease out what your particular BIOS version 
thinks it has available for drive types.

All,
With all of theother things going on in my life, I'm
making baby steps on getting the 1520 to see more

Currently, I'm working on a spreadhseet to take the

I do have a question, though.  My 40 MB HD reported

977 * 5 * 17 = 83045.
Did I miss a division by 2 somewhere?

I believe that the 17 is sectors per track and each sector has 512
bytes (~1/2 KB) and that is the factor of 2 you are looking for.

512 Bytes per sector on a PC hard drive.  That is your difference.

What do you need in the hdlook code to make your life easier?  I can
print in both Hex and Decimal. :-)

Mike,
hdlook isn't the "problem."  It was a big help in
getting me this far.
I believe I have identified the area in the ROM where
the drive geometery is stored.  There are ~46
different listings that fit the proper format.  One
odd thing about the table is every drive has 17
sectors per track.  I doesn't seem impossible, just
odd.

My goal is to convert the hex enteries back to
decimal.  Then, match the geometry listings to the
correct drive types.
I copied the entire table from WinHex to Notepad.  I
printed the results and I am entering them into Excel.
 I have Excel set up to do the Little Endian shift and
then the hex to decimal conversion.  
Once I have the conversion done, I'll match them up to
the drive model.  

What doesn't make sence right now is the text table
only lists 6 Conner drive models.  If there are only 6
models, why are there ~48 different entries in the
geometry table?

That's about it for now.

Subject: Re: CHS and Hard Drive Size

Actually, 17 sectors per track makes perfect sense, and is one of the
ways that I identify a drive as 'classic MFM'.  For a machine with a
specific controller, listing only MFM type drives makes sense.

Drive geometries only started changing when the drives got bigger and
the existing 'CHS' format wasn't enough.  First drives started lying
about their geometry, for example reporting more heads and less
sectors than they really had just to make things fit 'within limits'.
 After a while the BIOS of machines changed to accomdate the bigger
drives.

Now, for the second question.  The generic BIOS contracted to Phoenix
(or AMI?) would always have those drive types present.  My bet is that
Grid included the ID strings as a form of 'autodetect', not to lock
you into a specific set of drives.

Does my HDlook program tell you that the address of the currently
selected drive is in that table?  If so, I have a pretty easy/sleazy
solution.  A BIOS extension on a card can change that area of memory
to point at whatever drive you need after the onboard controller has
failed.  That would be simple to do, and does not require patching the
BIOS.  It does require a way to get the new EPROM into the system, via
a card slot or a cartridge.

(Having never seen a Grid in real life, I've heard they have some way
to do it.)

Mike,
If Grid left the "generic" drive types in the table,
then why the need for the text entries?
There is a table ("string" is probably a better term)
of 6 drive types.  For example, it says something like
"CP344CP3104CP322..."  So if the BIOS supports drives
not in the text string, why the need for the text or?
Could it be that Phoenix had a "standard" 286 BIOS
that they edited for for each customer?  HHmm...
That would explain why line 15, line 24, and lines
31-34 are zeros.

I haven't actually fired up my 1520 in a while.  IIRC,
HDlook does not report the address.  However, I could
be wrong.

The 1520 does not have a slot like a ISA slot or
something like that.  It has a "cartridge" area.  The
power supply (or battery) can slide into that area. 
The 1520 has a power socket on the back so power can
be applied there.  Since the cartridge area is open,
you can slide in some add-on "pods."  I have an
Ethernet pod and a GPIB (IEEE-488) pod.

I'm pretty sure I loaded the driver disks for both
pods to the files area.

Subject: Another Baby Step

All,
I posted a file (HD Conversion.xls) to the group.
It is an Excel spreadsheet of the supported hard drive values listed
in the 1520 Grid BIOS.
It is hex converted to decimal for easier reading.

The green and white are provided for contrast only.

May goal was to match each of the 6 supported drives to their table
entry.  The 6 drives are the CP3022, CP3024, CP3044, CP3042, CP344
and the CP3104.
Of the 40+ entries in the table, I was only to positivly match one
drive: the CP3044.  This entry is dark yellow.  I couldn't have done
it withoput hdlook.  Thanks Mike!

However, this "discovery" leads to more questions.  I have a 1996
edition of "The Hard Drive Bible."
In it, the CP3044 is listed as having 1047 Cylinders, 2 Heads, and 
40 Sectors.  They have a CMOS listing as 988 X 5 X 17.  HDlook
reported back 977 X 5 X 17.
The good news is the information that hdlook provided matches what's
in the BIOS table.  The questions I have are: where did they get the
1047 X 2 X 40, and how did they get to 988 X 5 X 17 from that?
Charles had mentioned a long time ago to me that the information
tine the drive table may be a mathmatical computation.  If that's
true, I would expect to get to 988 X 5 X 17 or 977 X 5 X 17 from
1047 X 2 X 40.
So, 40 - 17 = 23
5 - 2 = 3
23 * 3 = 69
1047 - 69 = 978

978 is so close to 977 that it seems like I'm on the right track
but, it's not making sense.  Maybe the Bible is off by 1.

If this method is the way the BIOS works, it's seems ineffecient.
It would have to query the drive, take the response, do the
subtraction, another subtraction, multiplication, and then another
subraction, remember those values, then search through the table to
see if the computed values match a table entry.  Granted, going from
977 to 1047 takes another bit (from 9 to 10 bits), but the OS is
already dealing with 16 bit values.

It would be nice to find other working drives and see what values
hdlook reports back.
Thanks again Mike for hdlook.  I couldn't have gotten this far
without it.

Not to muddy the waters more, but Seagate says the CP3044 has 980
cylinders, 5 heads, and 17 sectors per cylinder, or a total of 83300
sectors.

Your book reported 1047*2*40 = 83760 sectors.  This might be the
actual physical construction of the drive.

A machine of this era would allow a maximum of 1024 cylinders, 16
heads, and 63 sectors per track.  So to get around the fact that the
drive actually has 1047 cylinders, you can cheat on the math.  The
drive will actually report 980x5x17, which works out to be just
slightly smaller than the actual size.

 You guys are both a bit over my head, but the 1520
does have those 2 EPROM sockets which is where the
BIOS looks after the POST and, I imagine, the memory
sector which is used by the SCSI pod.(perhaps also the
other pods). Much like the Video or SCSI cards on a
desktop box. I have the documentation for my SCSI pod
and memory location where the pod hooks into the BIOS.
To my knowledge the pod-slot connection provides DMA.

 Still haven't had time to spend getting my 1520 up
and functioning. My life seems too busy at the moment.

 From the manual:

 The base address of the catridge determines where in
the PC's ROM Scan Space the SCSI Controller BIOS will
reside. The address is normally specified in
hexadecimal and can reside in one of four available
address ranges(CA00:0000 to CA00:1FFF, C800:0000 to
C800:0000, CE00:0000 to CE00:1FFF, and DE00:0000 to
DE00:1FFF).

------------------------------------------
In the Configuration section it also mentions that the
pod's ROM-BIOS uses "IBM standard INT 13 format" to
support 10 firmware services (read, write, return
parameters, etc.). The pod's extended firmware sevices
include format unit, SCSI return ID, SCSI stop unit,
and execute CDB(? perhaps to use a CD ?)

 I have an external SCSI Syquest removeable cartridge
HD as well as several external SCSI CDROMs which I
used mainly on my Ataris or Macs but have yet to set
up and use on my 1520. Of course that doesn't solve
the internal HD problem and while I doubt tend to
doubt if it will boot from the SCSI device, but I'm
not sure from other things it says in the manual.

I did some looking around and found "CDB" is a SCSI
Command Descriptor Block.
Some info about it if you're curious: A command
descriptor block is defined as a structure up to 16
bytes in length that is used to communicate a command
from an application client to a device server. 

Sounds like a typical Microsoft answer: techincally
correct, but useless. ;-)

So, Mike: The SCSI drive stuff sounds like it'll draw
me off onto a tangent.  Question: do you know if BIOS
code in ROM is executed once, or loaded to RAM, and
executed, or loaded to RAM, executed and stored in
RAM?

>From the info that Lawrenece provided, the SCSI drive
needs an 8K block.  Since that's 1/4 of the whole
BIOS, it can't be "shoe horned" anywhere into the BIOS
area.  It must have its own separate memory area - in
RAM.

Something to think about.

Subject: Re: Grid HD problems

Here is a quick tutorial on the boot process and BIOS extensions.
This applies to any PC, except for the earliest models of the IBM PC 5150.

At boot time the processor comes up a reset state, and starts
executing code from a pre-determined location.  That pre-determined
location is very high in memory, which is why the BIOS of a machine is
always very high in memory.

The first code that gets executed initializes the built-in parts of
the machine.  This will be the low level stuff, such as the timers on
the motherboard, the interrupt vectors for the floppy drive, divide by
zero interrupt, etc.

Eventually the machine is initialized enough.  Before the machine
tries to boot from a floppy disk or hard disk, it scans the 'ROM
areas' for BIOS ROM extensions.

The ROM Area is the memory between C000:0000 and F000:0000.  That is
normally 192K of open space that is reserved for add-in cards, if an
add-in card needs it.  SCSI adapters with a boot EPROM/ROM, Network
adapters with a boot EPROM/ROM, PCjr cartridges, enhanced IDE
controllers, video cards, etc.  all are examples of cards that might
have a BIOS ROM extension on it.

The BIOS ROM extensions do not replace the BIOS of the machine, which
is normally somewhere in F000:0000 to F000:FFFF.  They are extensions,
and augment the existing function of the machine.  The built-in BIOS
finds these extensions by 'walking through' memory and looking for a
magic '55 AA' in memory, which signifies the start of a BIOS ROM
extension.  If one is found, the code inside of it is executed.

It is at this point where a new hard disk controller card an
'override' the built-in BIOS.  How?  By changing the interrupt vectors
that were setup for the built-in controller and replacing them with
new ones.  This is how a bootable SCSI card gets control even if you
have a functioning non-SCSI hard disk adapter.  After the code in the
BIOS ROM extension runs, it returns control back to the regular BIOS
which goes looking for the next one.

After all of the BIOS ROM extensions are found, then the machine boots.


Now, for the specific questions.

Lawrence: when you send the Grid off send me the SCSI Pod too. :-)

Shawn: The BIOS extensions are always present, and they look like ROM.
 They will get run once before boot when the BIOS first finds them,
and they may continue to be used after the boot.  For example, if a
new disk controller is used, it 'takes control' from the existing disk
controller during the BIOS extension search, and then it gets used for
disk access from that point forward.  The existing BIOS code still
exists, but just isn't used anymore.


The general trick for getting the Grid to use another drive is to get
the BIOS to stop insisting on one of three specific drives.  There are
a few ways to do this:

- Fix the damned BIOS.  This is hard, and depending upon how the fix
is done it is not very flexible.

- Add a new ROM into the system that looks like a BIOS extension, and
have it do the fixup to the hard drive data areas.  This is kind of
what a new controller in a regular PC does, but you would still be
using the existing controller hardware.  (Remember a few years ago
there were 'IDE extenders' that let your PC use bigger hard drives
without getting a new controller?  Same trick ..  they were just a
BIOS ROM extension on a card.)  For the Grid Lawrence mentions that
there is an interface for installing ROM chips.

- Add a new controller, such as a SCSI Pod.  Not only does this supply
a new ROM BIOS extension that takes over the hard drive functions, but
it adds new hardware.


I would go with the second option.  It would be trivial to write code
for a BIOS ROM extension that could setup the onboard hard drive to
whatever you want.  If there is room in the CMOS configuration memory
you could even have it read the values from there, so that you
wouldn't be locked into a specific hard drive.  (You would need
software to set the drive parameters in the CMOS, as the built-in BIOS
can't do it.  That's pretty trivial too.)

I can write the code to do this.  Lawrence has even offered me a Grid.
 But I don't have an EPROM burner, and I'm even shorter on time.  And
this is all based on the theory that a ROM BIOS extension can 'fix up'
what the onboard BIOS is choking on.  I'm sure it can, but until it's
tested and working it is just a theory.

Whew ..  sorry about the length of the reply here, but I wanted to be
thorough.  If you want to see what's in your ROM extension area, check
out this web page:

  http://www.brutman.com/PCjr/pcjr_cart_dumping.html

It's written for PCjr owners, but the software (my creation) works on
*any* machine, including your newest 4Ghz behemoth.  The theory of
PCjr cartridges is the same .. they are just ROM BIOS extensions, so
the code handles both.

Subject: Re: [RuGRiD-Laptop] Digest Number 552

 I should add that the SCSI controller is a "Future
Domain TMC900 Gate Array" and that as well as the 4
selectable ROM-BIOS Base Addresses there are also 2
selectable interupts : IRQ3 or IRQ5, which means they
are configured like the swtches on motherboards or
modems while the architecture is being acknowledged.

Under the title Disk Drive Interfacing, sub-title Hard
Disk Drives: The ROM BIOS firmware of the SCSI
Cartridge searches for hard disk drives starting with
SCSI address o, up to SCSIaddress 5. ..............>

 That would seem to indicate to me that the Grid BIOS
is just re-directed to the SCSI ROM BIOS and pointers
would be placed in one of the selected Grid BIOS areas

to the SCSI services on the pod BIOS. I'm becoming
more hopeful about the SCSI HD being bootable.

 One thing I've noticed about the pods and any
external
FDDs is that they are all configured by switches. The
default bootup order is the EPROM(R),HD(H),FDD(F). I
keep thinking one of the overlay programs such as
Seagates Fast-Track or one of the other HD programs
could be loaded from the EPROMS. Dont most of them
read the MBR(?) on the HD for sectors and such ?

 The CMOS is on the Dallas chip and is minimal.

                   Lawrence:
I did some looking around and found "CDB" is a SCSI
Command Descriptor Block.
Some info about it if you're curious: A command
descriptor block is defined as a structure up to 16
bytes in length that is used to communicate a command
from an application client to a device server. 

Sounds like a typical Microsoft answer: techincally
correct, but useless. ;-)

So, Mike: The SCSI drive stuff sounds like it'll draw
me off onto a tangent.  Question: do you know if BIOS
code in ROM is executed once, or loaded to RAM, and
executed, or loaded to RAM, executed and stored in
RAM?

>From the info that Lawrenece provided, the SCSI drive
needs an 8K block.  Since that's 1/4 of the whole
BIOS, it can't be "shoe horned" anywhere into the BIOS
area.  It must have its own separate memory area - in
RAM.

Something to think about.

      Hi guys, My name's Phil. I have two 1530's which which I have a
couple of problems, and it seems that you are addressing both of them
here in this thread. My first unit is a standard 1530 with amber
monochrome screen which boots but will not recognize the hard drive.
The HD is a conner C3044 as it should be, I think. I've tried booting
it up with the GRiD DOS 3.3 on floppy, but none of the utilities I
sue will see the HD. Gridscan reports "O Mbytes" for the HD and the
HD light comes on permanently after that. The drive also has a high
whien to it which makes me think it might be bad. I would be willing
to take it out and try to hook it up to another machine. I do have an
old WIN98 I might be able to do that with, but the power connetions
look hard wired. Are They? There are two application sockets that are
empty. I wonder if those can be used for the cartridge ROMs?
      I recenty bought that machine, but my second machine is the
oone I originally bought back in 1986 and still have. IT is upgraded
to a color screen. MY problem with it is that most of the time it
will not boot. When it this happens, I'll get a few clicks from it
and there are those vertical lines on the screen and it freezes
there. I've seen others on this thread complain about that. However,
on my machine, it doesn't do it all the time. If I leave the machine
sitting for a long time then it will usually boot, and everything
works fine (except the backlight, but I'll get to that later). But as
soon as I turn off the machine and try to turn it on again, it will
hang again and not boot. Even if I try it several days later, it
won't boot. I usually have to wait like two or three weeks before it
will boot again. It's not the battery (I'm sure of that), but I can't
for the life of me figure what makes it do this.
      Any suggestions or help would be greatly appreciated.

Subject: GRiDCase 1530 problems

Hi guys,
     I tried to post on a reply, but I'm not sure it got through, so
I'll try again here.
     I own two 1530's. Both have some problems. The first one I
recently bought will boot, but does not recognize the hard drive. I
see in the thread that this is a common problem being seen. I have
tried the GRiD DOS 3.3 and fdisk will not see it. Gridscan reports
only "0 Mbytes" and then the HD light stays on all the time after
that. The HD also has a high pitched whine and I am not sure if it's
okay or not. I am not sure if I can remove it from its PC board as it
looks hard wired into the power connections. Is that the case? Does
anybody know? If not, I would take it to and try to see if I can get
it to work with an old 98 machine I have. However, there are two IC
slots open on the video board area, and they seem to be indicated for
application ROM's. There above the keyboard to the left side. Can I
use these for Additional BIOS ROMs as you have been talking about in
this thread? The HD is a Conner C3044 model so it should be
recognized if it works. I would be interested in procuring another
one just in case though, or following through with your present
research to reprogram an EPROM if perhaps another HD could be
substituted.
      My second machine is the one I originally bought in 1986, and
have had since then. I upgraded it to a color screen and 30 watt
power supply in 1987. My problem with it is that most of the time it
will not boot up. It will hang right at the beginning with those two
sets of vertical lines, on upper and lower halves of the screen.
However, if I let the machine sit unused for a long period of time,
like three weeks to a month, it will usually boot up, and work fine
(except it won't backlight, but I'll get to that later). But if I
turn the machine off and try to boot it up again, it will hang and
not boot. Even if I let it sit for several days, it won't boot. I
usually have to let it sit for a very long time before I can get it
to work. I'm pretty sure it's not the lithium battery. (But I need
another one anyway. Can you tell me where to get one?)However, this
problem is annoying me and I would really like to keep this fine
machine working.
      Any help or suggestions would be greatly appreciated. Thanks.

Hello there, Phil.
My name is Shawn.  I mostly work with the 1520's but
I'll respond.  The emails that you replied to at the
bottom are in reference to me working on some 1520
issues with another gentleman named Mike.

As far as booting and not seeing the hard drive, it is
most certainly the hard drive.  We're dealing with
~1990 technology that is now over 16 years old.  Many
times, the head will stick to the disk platter
preventing it from turning.  Or, the grease in the
bearings leak out preventing the disk from turing or
preventing the drive from reaching full rotational
speed.
I don't have a 1530, but I'm 99% sure the drive is not
hard wired.  If it's like the 1520, there is an
interface board mounted to the read of the drive. 
That board should just pull off.  IIRC, the power
connection is snug, so you might have use some force
to pull the pins out of the power connector.
And yes, once the drive is free, you will have to use
an old computer to mount (or see) the drive. 
Windows98 should work fine in recognizing the older
FAT.
Since I don't have a 1530, I'm not sure of the
location of the sockets you're referring to.  If they
are on the display driver card, then I don't know what
they're for.  My 1520's have empty sockets there and I
don't know what they're there for.  If these sockets
are above the keyboard area, then they are for the
ability to run DOS (MSDOS or GRiDOS) from ROM.  The
(E)PROMs would fit into those sockets and instead of
booting from disk, the machine will boot DOS from ROM.

As far as the second machine not booting, I don't know
for sure.  However, an idea might be the power supply.
 I think the amount of times since the last boot is a
coinciedence and not an indication of the problem.  It
may be that the power suplly is not able to handle the
amount of current that your 1530 needs in order boot
up.  The times that is does boot up might just be
luck.  It may be that the power supply is bad (or
going bad) or is not the correct supply for that
model.
The 1520 needs 16 volts DC and I've seen it pull as
much as 2 1/2 amps at initial power up.  It will
settle down to about 1 1/2 amps and then just under 1
amp when the hard drive spins down.
One common mistake is to try to power the GRID from 12
volts.  Most of the time, this doesn't work.
I don't know the power requirements for the 1530.  If
you have access to a separate power supply, you might
try using it instead of the GRID power supply and see
what that gives you.

Well, good luck and let us know how things go.

Date: Sun, 21 Jan 2007 22:32:37 -0000
From: "jeriddian"
Subject: Re: Digest Number 523

Thanks so much for answering, Shawn,
       I successfully powered up the machine that normally won't
boot this weekend and managed to get a dump of the ROM contents with
the ROM dump program that Mike B had recommended. However, once I
powered down the machine this time and tried to start it up again,
it did not boot as usual, except this time, there was no clicking of
the HD. It would start to spin, then stop spinning, then start to
spin again, then stop spinning again. So I do think it is the HD
that is the problem here. Of course I got the vertical lines on the
screen when it did this.
       However, I also believe you may be right about the power
supply. This time, my backlight on my video came back. I wonder if
something burned out in the HD which allowed the power to be
diverted somehow to the video and allow it to backlight up again. So
I think I will look into replacing the power supply to the unit
first.
       But past that, I think both units will need their HD's
replaced, so I am interested in the modifications to the ROM that
are required to do this. Actually I have some old WD cavalier drives
at 80 MB which might just fit in there. I have to look and see if
they will. I still have to see if they are any good though. But if
so, I am very interested in the ROM modification to allow this.
       On my newer machine which only has the HD problem, I do
believe that the video card is not just the video card. The video
just happenes to be on it, but I have the original booklet which
describes how to insert the cartridge ROM chips and it does indicate
that the placement of those IC sockets is exactly the right place,
although the actual picture of what the sockets look like are
different, but the location is the same. However, on my older
machine that won't boot, when I upgraded it to the color screen,
they replaced that card, and this one has no IC socket for a
cartridge ROM, so if I replace the HD on it, I'll have to modify the
original ROM chip. I'll do it, though I'm not looking forward to it.
       Any idea where the MoBo ROM chip is located on this? I know
you work on 1520's, but I was kind of hoping. Also, there was a 1530
ROM update program on the website that Mike B. recommended for the
ROM dump program. Do you have any idea if that would apply to my
machines at this time?
       Again, thanks so much for your help. I'll keep you all posted
on how things go.

Phil

Mustang,
Basically, the computer is not seeing the hard drive.
I'm not a 1750 expert.  They're a little "too new" for
me.  Does the 1750 have a BIOS screen that allows you
to configure the BIOS?
If so, you might see if the HD is enabled.
If it is enabled, it is very possible that the hard
drive is bad.
When was the last time that it worked for you?

Subject: Conner HD Problem

 Hi Shawn. Should that actually be Sean ?

 Hasn't been too much activity lately. I almost posted
a happy New years message just to show Yahoo it is
still active. Happy New Year to all the Gridders just
the same.

 The problem remains with the casualty rate and small
capacity of the Conner HDs. Have been involved with
other hardware problems as well as home renovations
and haven't played with my dead HD 1520 for a while
but it still occupies a corner of my heart. Mike was a
competent breath of fresh air but the problem lies
unresolved.

 Have you had any contact with the guy who had a bunch
of boxed Conner HDs ? Another angle might be with
appealing to the guys on the "Former Grid Employees"
mailing list (one of whom contacted the group some
time ago) who surely can't just sit by and watch the
1500s enthusiasts slowly ride off into the sunset.

 One self-serving motivational scheme is that I could
send Mike my second 1520 (with it sitting in his
workroom, could he withstand the challenge ?) and
maybe pull him away from his IBMjr fetish long enough
(he does also have a programming job with IBM which
pays the rent) to solve this vexing problem. In return
could I pry you loose from one of your Ethernet Pods ?
Deal done when he receives my 1520. IIRC you have 3 of
them, more than 2 is like a 3rd wheel on a motorbike.
This could also serve as motivation to me tofind a
solution to the Conner HD problem. :^)

Hey Lawrence,
It is, in fact, Shawn.  My wife constantly reminds me
that its the "girl way." ;-)

I agree that the Conner drives are failing.  The guy
who said he had the hard drives never responded.  I
just checked and he still is a member on the list.  I
emailed him twice and never got a response.  If you
want to try, go ahead.  His email address is
david.purnell43@... 

I remembered looking at the former GRID employee site
a while back.  I think I signed up on the list and
never received any email from it.  I searched the
messages and saw that the listed the site as
www.mumbo.org.  If you go there now, it's a cave
exploration site.

As far as Ethernet pods, I only have 2.  I also have a
GPIB (IEEE-488) pod.  Sorry, but I'm not up for
getting rid of one of the pods just yet.
I do have 3, 1520's.
If Mike's up for it, I could send Mike one of mine. 
It depends on what Mike wants to do.

There has been activity at my end.  Now that the
holidays are over, and Pinewood derby is over, I have
some time to devote to GRID's.  (As a side note, I
used a 1550 and a Gridcase stacked on top of each
other as a step-stool to my workbench so my son and
step-son could saw and sand their Pinewood derby cars!
 They weigh about 80 lbs (36kg)!  Try that with
today's laptops!)
I will now bore everybody with the details.  Some of
you may remember that I have a Qualtec EPROM
programmer.  About a year ago, I damaged the power
supply by plugging 12V AC into it instead of 12V DC. 
That forced me to borrow a EMP20 from my job.  The
problem with the EMP20 is the software was made to run
on older, slower PC's.
I took down my Linux box, found an old 4.3 GB HD,
loaded DOS 6.22 on it last night(it can only see 2
GB-which isn't a problem).  I also downloaded Mo'Slo
to slow down the blazing fast 666 MHz processor. 
Didn't Mo'Slo used to be free???  I paid $15 for it.
:(  Anyway, I'm going to load the EMP20 software and
hopefully start working with EPROMs.
I have two versions of Grid 1520 BIOS.  I also have a
Connor CP3044 hard drive.  The older BIOS won't
recognize the CP3044.  The newer version sees it and
boots from it.
The weird thing is the drive tables in both versions
of BIOS are exaclty the same.  There is a separate,
short text table.  The text tables are different. 
However, in the past, I know I've changed the table,
burned new PROMs and it still didn't boot.
So this time, I going to do the process again, take
better notes, and hopefully have better results. 
Also, I bought a 340 MB Connor from Ebay several
months ago.  The true test will be getting the 1520 to
boot from that hard drive!
Sorry to bore everybody with the details.  But, I am
making (very) slow progress.

Just want you to know that I'm not ignoring you guys, just extremely busy.

I need three things to experiment:

- Grid.
- EPROM burner
- Time

I have all of the BIOS references, asm books, and some limited BIOS coding experience.  (Enough to
do this at least.)  The Grid is easy to obtain, and Lawrence has offered me one more than once. 
#2 and #3 are tougher.

The 1750, like the 1755, has a setup file that you use to get into the
bios. You can still download them at the ARI link (above).

I have the manual for the 1755, and I'd be happy to look stuff up for you.

I can't help you with the HDD problem, haven't crossed that one yet.
Also, I just run dos 6.22 on mine for games and stuff.

Would love to get own a working 1530, 1550 or 1580, and a GRiDpad
(2050, I think, right).

This list is a gold mine, even for people like me who own the "toy" GRiDs!

sorry guys for getting back to you so late, been extremly busy with

since i have owned it. i recently got from a relitive that past away.
but before he past away, he was working on a personal project for data
aquiring stuff for cars(1/4 mile times, 0-60 times, O2 sensor read
outs, and other various monitors) and this software that he was
developing is on this laptop. so, at one time, it has worked recently.
other than that, thats all i know about it. and Steph, if the HDD is

Andrea,
I am very impressed with your work on your 1520!!  You
did a very good job and you took very good pictures.
I am sorry, but I do not have a replacement plaza
monitor to give to you.  
I have 3 1520's.  Two do not have the Dallas chip, one
does have the Dallas chip.  The battery inside the
Dallas chip is dead.  I am working on a hard drive
problem with my older 1520.  When I finish with that
problem, I will modify the Grid with the Dallas chip
by adding the 3V battery.  I like how you placed it
near the RAM.  Good work!!

Do you have an EPROM programmer?  In your pictures, I
see the BIOS is different from the two versions that I
have.  I would like to copy the two BIOS chips.

I have another question: what are the green wires for?
 Is that an extra Reset connection?
Thanks you,
-Shawn

Subject: My first GRiD, a 1755!

My GRiD 1755 finally arrived, and I really like it. I had no idea a
computer could be so well built! I got it off eBay, for a mere $27
shipped, with insurance. When I boot it up, I get an invalid
configuration error, so I guess I need a floppy with the setup stuff
on it. Anyone know where I could get an image file?

Also during bootup, I get the message 'hard disk failure,' but I think
that it was just wiped before it was sold, because I can hear it spin
up just fine. Along with the 'hard disk failure' thing, it *sometimes*
says 'key stuck error'. But only sometimes. And it for some reason
doesn't want to boot off my DOS6.22 floppy. Is it because it can't
boot DOS 6, or it can't read HD floppies? (or maybe my disk is bad). I
just find it odd that a 486 era computer can't read a HD floppy; my
386 IBM used to be able to read/write them all the time.

If the HDD really is bad; I'd like to replace it. Judging by the size
of the GRiD, I'd guess that it uses a standard 2.5" IDE drive, which
is great, because I have a few laying around I could donate. Does
anyone have a manual for getting in there, or if not, any tips on
doing so?

Thanks a ton!

Alrighty, I solved the 'key stuck error'. Turns out it only happens when
numlock is on. *shrug* Also, it *does* read HD disks, my DOS6.22 floppy
was just messed up, it boots my DOS5 one just fine. Once booted off
that, I ran 'chdsk c:' and I get 'Not ready error reading drive C.'

It's been awhile, but let's see what I can recall.
Nearly all the GRID 1755s had 386 chips. At the very
end, they modified some to include a 486- like the one
you have. The BIOS remained unchanged- as I recall,
they used a BIOS overlay to make the unit recognise a
larger hard drive (EZ BIOS, Easy BIOS-something like
that) maybe 120MB. The bad news is that you may lose
your mind trying to get a new hard drive to work.
However, I think I have a conner drive in a 1755/486
that someone password protected. Since the password
blocks the Bios and not the drive, it should work. Let
me know if you are serious about bringing the little
beastie back to life.

Subject: Re: [RuGRiD-Laptop] Re: My first GRiD, a 1755!

Yeah, I was planning on the HDD being a HUGE pain, but some fiddiling  
with fdisk showed that the pervious owner split the drive in to 6  
parts for no reason, and all the parts weren't even properly  
formated. So I deleted them all, made a new one, and installed DOS 5.  
Its working fine now.

I did some poking around on the yahoo groups GRiD's page 'files'  
area, and I found the 1755 setup. I am able to run everything, but it  
informs me that both the clock chips has lost power (could I tape a  
AA in there or something?) and 'memory size miscompare'. When I am  
done running the setup, I hit F2 (save and exit) and when it reboots  
it *still* says - "Invalid configuration - please run SETUP again"  
then it thinks for 30 sends, and prints 'Hard drive failure' then I  
press F1 and it boots off the HDD to the C:\> prompt, which I find  
very strange.

I thought it was just because the clock battery is dead, but when I  
run setup agian, all my previous values are there, so I have no idea  
whats going on. I presume that something is set wrong, and its  
getting confused at bootup.

Subject: Uhhh.... oops... (?)

I was trying to find out what might be causing the "Invalid
configuration - please run SETUP again" message, so I started up the
SETUP program, and started trying different settings. I came across
one; it was shadow mask something, and it was enabled. I pressed F1 to
get info about it, and it said that if it was enabled, you need to
have some file (I don't remember the name). I figured that since it
was a totally fresh install of DOS5, I most likely *didn't* have that
file, so I disabled it, hit F2, and rebooted.

That was a mistake. Now whenever it boots, not only do I still see
"Invalid configuration - please run SETUP again" but after I hit F1 to
continue, I get the message "Non-System disk or disk error. Replace
and press any key when ready." What I don't get it why it doesn't even
remotely try and access the floppy drive...

In any case, is this thing borked already or what? Can I get 'er back?

*sigh*

Well, now (or whenever I get it to boot) its got DOS5 on the internal

I'd rather run MInix2 on it though, its got alot more features.

 Thank you Shawn,
 and thank you to the ruGrid group where I have found all the
necessary information for my work.
Yes, the green wires comes from the Dallas and they are connected to a
microswitch for the reset. I put the microswitch near the extra Rom
socket because it'is easy to reach when the computer is closed.
For the Bios, I have an old Eprom programmer with Isa slot working on
a 386, but I never used it before, next week I'll try to copy the
binary of the Bios and post on the Group files..
now a question..
the second 1520 seems really different from the other,
this version has only the big hard drive, a conner cp3104,  the
controller is different, no modem card and there is a battery on the
motherboard for the Cmos,  the other has
the floppy and the Cp3024, a modem card, and the Dallas.
How many different version exists for the !520?
and why the bios is different?
Thank you Andrea

From: Shawnerz
Subject: Re: [RuGRiD-Laptop] Re: My second GRid 1520, just arrived with broken plasma monitor

Andrea,
I know of 3 different versions of the 1520
motherboard.
Version 1: Varta TL-5101 battery for time of day and
other CMOS configuration, BIOS EPROMS (27C128), BIOS
checksums 0B00 and DE00.
Version 2: Same as version 1 but One Time Programmable
PROM chips used for BIOS (27PC128).
Version 3: Dallas DS1287 used for time of day, same
BIOS EPROMS (27C128)used but, checksum 7A00 and 2F00. 
This would indicate a new version of BIOS.

In your pictures, the BIOS checksums are 4200 and D000
(? the picture is not clear).
Because this does not match the other checksums, I
think this is a different BIOS version.

You asked two questions: how many different versions
exist for the 1520 and why the different versions.
I do not know the answer to both questions.  I thought
there were only two versions.  Your picture that shows
the different checksum shows there are (at least) 3
versions.
I do not know all of the reasons for the different
BIOS versions, but I can take a guess.  The old
version BIOS (with checksums 0B00 and DE00) only
support 3 hard drives.  The only hard drive you can
run in those systems are the Conner CP3022, CP344 and
the CP3104.
In the BIOS version with checksums 7A00 and 2F00, they
support 6 hard drives.  The supported drives are the
ones listed above and the CP3024, CP3042 and the
CP3044.

The 1520 has several optional pieces of hardware.  One
is an IEEE-488 (also known as GPIB) interface. 
Another piece of hardware is an Ethernet interface.  I
am not 100% sure about this, but I guess that the
different BIOS versions to allow the different
hardware (GPIB, Ethernet, Dallas RTC) to be used with
the 1520.

If your EPROM reader in your 386 does not work, I will
pay you to have the chips sent to me.  I will read
them and send them back to you.

Thank you very much,
-Shawn

Hallo Shawn,
I found on my two laptops some new information:
The version with the Bios checksum Even 4200 Odd DD00
(I'll post the two binaries, could you check for me if
they are ok?) is probably the most recent of the two I have.

on the back there's a silver label: tracking K54570

CPU Intel 80c286-12
math co-processor added in a second time 80287xl
Dallas Ds1287A

Floppy disk drive 31/2
Four banks sipp memory module 256
The video card is exactly the same for the two 1520 but the first has
a backlighted lcd screen the other a plasma monitor (broken).
Next time I'll try to swap the monitor to check if it works
Video Assy no. 104056-00 rev. N
Ser. no. 030689
Yamaha V6366C
the Power supply card is different probably because the floppy drive
and cp3044 need less power than the cp3104.

Power supply M/N DC20W4P-115F for the laptop with the floppy
and cp-3024 and M/n DC38W4P-1166 for the laptop with thecp3104

Both have inside the dock bay  a switching power supply, but on the
Grid with larger hard drive one of the two connections is isolated.
Any idea?

The laptop with plasma have:

BIOS eprom checksum 7A00 and 2F00.
8 banks sipp memory module

Subject: Re: [RuGRiD-Laptop] Re: My second GRid 1520, just arrived with broken plasma monitor

Andrea,
I am very anxious to see the binaries when you post
them.  I will look for the new files.

I mentioned before that I have 3 1520's.  Two of the
1520's have the DC20W4P-115 power supply.
I am guessing, but:
"DC" = DC supply
"20W" = 20 watts
"4P-115" = don't know.
The last letter is probably a revision designation.
The newer power supply says "38W" and I guess that
means 38 watts.

I do not know why one of the contacts is isolated. 
Grid made a battery module that will slide into the
docking bay.  The battery could power the laptop.  If
the battery is in the docking bay and the 1520 is
powered by the 16 volt DC connector, the 1520 will
charge the battery.  It is possible that a previous
owner did not want the connector to make contact with
something.  Or, maybe the charing circuit is defective
and the previous owner did not want the charging
circuit to damage the battery.

Thank you for your information and I hope my
information helps you.

Subject: Another BIOS Version

Wow!  I am very impressed.  
Andrea, I received the files, then I merged the two
together and I thought there was some sort of error. 
The characters didn't look right.  It is difficult to
explain.  But, I've been working with the BIOS files
over the past 3 years when I get time.  I have
developed a "feel" for the character patterns.  As I
scrolled through the file, it didn't "look" right. 
The characters looked odd - I thought there were
errors in the file.
I looked more closely at the file and realized it
wasn't errors.  This version of BIOS has messages in
German, French and English.

It is also much larger than the other versions.  The
other versions end at $5D4C and fill the rest of the
address locations with "FF."
This version takes almost all of the space of the
chip.  There are some blank blocks, but there are not
many of those.

This version is similar to the other two version in
that it only supports 6 hard drive type (Conner
CP3022, CP3024, CP3044, CP3042, CP344, and the
CP3104).

If anyone is interested, I'll put the files in the
Files location.
When I get time, I'm going to program the files into
new EPROMS and see how my Grid performs.
Thanks again, Andrea.

Speaking ROMish...  FF is an empty byte, and can be written over.  but 
will blow up the checksum.  If there is a boot check address in that 
aria then additional boot code can be added. Perhaps, an ATA-boot.

Anyone trying CF cards out there?

Subject: Re: [RuGRiD-Laptop] Another BIOS Version

Charles,
You bring up an interesting topic that I wasn't going
to bore the group with.  But since you brought it
up...
There is a long version of the story, but I'll tell
you (and everyone else the short version).
The first, 64 (or so) bytes is the Phoenix BIOS
copyright notice.  So, I make whatever change I need
to make, then compute the checksum.  Let's say before
the change, the checksum is 1000.  After the change,
it is 1004.  Then, I take the first letter of the
copyright notice and change its value 4 ASCII
characters less.  This way, the checksum stays the
same.
The logical question is, why not just change the
checksum value.  The reason is I can't find the
checksum bytes. Let's say the checksum is DE00.  How
many times does DE00 appear?  I think it apears twice.
 And, it's not near the beginning of the end where
you'd think it should be.  That's because the checksum
will really appear as 00DE.  There are a lot of places
where that appears.
The bottom line is, it's much easier to manipulate the
copyright notice to keep the original checksum, than
it is to find all the possible values, make the
change, save the file, burn the PROM, and test it out.
I wish I could take credit for that idea, but I didn't
come up with it.  I read over that post from the guy
in Germany that got is 1530 (or was it a 1535), and
that's what he did.  That post was originally on Rob's
Grid board but it found it's way over here too.


You mentioned this:

That's way above my skill level.

I totally forgot about Compact Flash.  I've been
focused on the hard drives.  I am very close to
success with the hard drive solution.  I was able to
get an older version of BIOS that didn't support the
CP3044 hard drive to recognize and boot from it.  Now
I know what I have to do to get the 340 MB drive to
work.  The problem is time.  I won't have time to work
on it this weekend.  The GRIDs will have to wait a
week or so.

I wasn't going to tell the long version of the story,
but it looks like I did.  Sorry if I bored everybody.

Subject: Re: [RuGRiD-Laptop] Another BIOS Version

Aah... but there is an easy way to verify a checksum that will probably 
set a different final number to check against.....

Here is the logic.
One add, and one jump-if-zero is allot less machine effort than "if 
chksumA = checksum B"

You know that a 16 bit add will spill over the top and generate two 
flags, zero, and overrun.  so you add the difference, ignore the 
overrun, and check the zero flag, you have arrived at a quick checksum 
test.  Two minimal cycle machine commands, and an address pointer.
Another would be to use logical commands like and and or to mask down 
the number. than jump on zero to wherever...  So searching for the 
checksum now becomes a bit more complicated.  You are looking for the 
checksum (raw), FFFF-checksum, zero-checksum and 2-s compliment of the 
checksum.  Also there is no expected location to store the comparison 
(constants) becasue it could be embedded in the check code.

I just came across one original manufacturers brochure, and one from a
Norwegian dealer, so I scanned them with 200dpi and uploaded them.
Enjoy.
If anyone wants even higher resolution pictures or pdf versions, just
email me, and I'll scan and send it to you.

Hallo André
nice pictures, I'm interested in the high resolution versions.
I'm still looking for the Owner's manual for the Grid 1520. Could you

Hehe, well, the pictures already there does leave something to be
desired.. But in this age of affordable digital cameras and
cellphones with decent cameras one could want to have pictures of
more of the GRiD models. I did notice that Yahoo reduced my 1MB scans
to just 78kB so maybe the Files section is a better place to put
selected pdf (or jpg) scans if there is a lot of interest, but I
guess the storage space is limited.
I also have the 1500 Series Owners Guide, a GRiD Server-User's Guide,
and a Product Update Supplement for MS-DOS Release 3.3 (from GRiD
Systems). All of these are many pages so don't ask me to scan all of
them at once.. And also remember to reveal your email address to me
somehow if you want me to send you something..;)
Glad to be of help.

Andre,

I have been watching from the sidelines for reference to the 1535 exp 
and it seems you might have some good info.  Would you be so kind as to 
check the 1500 Series Owners Guide for a method to direct the video 
output to the 9 pin video connector at the rear?  A commonly used 
keystroke on some other laptops is CTRL-D.

    The keystrokes to switch the video to an external monitor are as
follows: CTRL-ALT-TAB all pressed at the same time. At least that's
the way it is on the 1520 and 1530. It shouldn't matter whether it's a
9-pin or a 15-pin I think, but it surprises me a little that your unti
would have a 9-pin only. VGA was already available to the computers by
that time as evidenced by the earlier models I just referenced.

Thanks, it worked.  In all my poking at the keyboard I must have missed

It seems to be EGA but I must scrounge one up for testing to be sure.

The 9-pin is CGA according to the brochure. The 15-pin VGA is an option
you put into the battery/PSU compartment.

Subject: SUCCESS!!...kind of...

All,
Well, I was finally able to get my 1520 to see another
hard drive other than the 3 listed in the BIOS
firmware!
That is the short version of the story.
The long version is I did what the other guy did with
is 1535: changed the text field, changed the drive
table, corrected the checksum.
I finished at about 11:30 last night.  Getting the
1520 to recognize the 340 MB drive was an important
first step.  
I have a 340 MB, Conner drive in the 1520.  I can
mount the drive and browse the directories.  I have
not run fdisk on the disk yet.  I am booting MSDOS 5.0
from floppy.
I brought the hard drive from Ebay back in October. 
The seller listed the drive as a 420 MB drive.  The
printed label (from Conner) on the drive says it's a
Conner CFS420A , 320 MB drive.
I put the drive into my desktop.  The desktop BIOS
POST (Power On Self Test) message says the drive is a
CPA320B.  I went into the Setup on the BIOS, and Setup
reported that the drive is a CPA320.
So, when I made the new Grid BIOS file, I entered
CPA320 as the drive type.  It worked!  I could barely
believe it.
There is one point I want to stress: I WOULD NOT HAVE
BEEN ABLE TO DO THIS WITHOUT hdlook.exe!!
Thanks Mike!!  Even though I didn't boot from the
drive, hdlook was able to report the correct drive
parameters for me to enter into the drive table.  It
would be nice if it were able to report the name of
the drive, but I'm not complaining.
I still have work to do.  I need to format the drive,
install the OS and boot from it.
Then, I'll move onto Compact Flash.
Cheers,
-Shawn

Well Done!

Your technique will almost always work.  The next step would be to store the drive parameters in
CMOS (or on a cart) and to patch the BIOS to get the drive parameters from there, instead of
having it hard coded in the BIOS.  Other Phoenix BIOSes do this, and I understand how it works at
a high level.

For the short term it would be better to write a program that finds the drive table in the BIOS,
allows you to enter new parameters for an entry in the drive table, and gives you the modified
checksum byte to use.  That will speed the process up.

Charles,
OK, sounds good.  One question I have for you is how
did your BIOS patch program locate the drive table (I
think you called it the "DCT") in the BIOS?  Did you
hard code the program to always go to the same address
location, or did you search for it?
If you searched for it, what parameter(s) did you use
for the search?
I ask because there are (at least) 3 different 1520
BIOS versions.
The drive table appears to be the same but at
different address locations.
Also, the text field for the drive type are of
different sizes and different address locations
depending on the BIOS version.

I think I remember looking over your source code, but
I have only had an "Intro to C Programming" class.  I
was quickly in over my head. :-)

This sounds great, guys!

I need to find out if another hard drive besides a Conner can be used
for this. I have some old Western Digital Caviar 280 Hard Drives from
that era which are 80Mb. Where can I get the HDlook.exe file? If I
can get the parameters for this hard drive, is it possible to put its
designation in the drive table or does it have to be a Conner Drive?
As to the source code I thought it would be standard 80386 Assembly
language for this sort of operation. I'm hoping that you all can come
up with a step by step procedure by which we can reprogram the BIOS
and use a different hard drive. Thanks for all your hard work.

It is hard coded to a fixed address based on a post I got on Rob's GRiD 
board.
If there is a way we can search the table this would possibly allow us 
to alterer other Phoenix BIOS

This my be a consistent method through all Phoenix 86 BIOS.

Yah...  Wait until you start working with  object oriented

Jeriddian:

I have used the WD fisheggs in the past with success.  The key is that 
they fit onto the backplane, so any drive has that same connection-edge 
footprint will work if the BIOS is altered to make it.

Jeriddian,
I haven't read Charles' email yet.  I hope I don't
repeat what he said.
Anyway, yes, you should be able to use your Western
Digital drives.
hdlook.exe is availible from Mike B.'s site.  Sorry
Mike, it's late and I can't remember your last name. 
Do you feel comfortable putting it in the Files
section?  Also, is it considered "public domain"?
The source code was Visual Basic??? I can't remember. 
Charles?
As far a step by step procedure, the full process
involves a EPROM programmer and a hex editor.  It's
not as simple as running a program and saving it.
Mike mentioned a way of making the hard drive appear
as a cartridge through some sort of BIOS patch.  I
don't know...it's probably very possible, but it's
above my skill level.
I hope this helps.
-Shawn
