This is a newer version of GRiD-OS designed specifically to run on the GRiDCase. It also features a newer version of the Initialize Media disk formatting utility that will work with 3.5", 720kB floppy disks. Unlike version 3.1.5D for the Compass, this version does not support multitasking. You can, however, replace Executive.run with a newer version (such as the one from GRiD-OS 3.2) and get multitasking. Just keep in mind that it eats up a lot of memory and is useless without at least 512k of RAM.

The disk here is for GRiD-OS. As such, you will need to format the floppy disk you want to use with the GRiD-OS disk formatting utility (Initialize Media) before writing to it in ImageDisk. In order to format a 720kB disk for GRiD-OS, you'll also need to use a newer version of Initialize Media.


Disk Type: 720kB, 3.5"
Disk OS/File Format: GRiD-OS
Disk Image Type: ImageDisk (.imd)
