If these are 52-sector 8" ISIS disks,
Yes. Double sided. 26 sector per track. Double
Density. 256 byte per
sector.
I can probably help with a bit of C code to extract
files from the
images. Drop me a note and I'll pass it along.
Not really necessary. The files on those disks looked quite uninteresting.
It was just that curiosity that hit me when I was browsing through the
hexdump. I now have concluded that the second disk is infact a disk for a
Tandberg TDV21xx machine. The TOS operating system is supposed to have
similarities to ISIS. The disk structure and the presence of files like
ISIS.DIR, ISIS.MAP etc among othes.
Hasn't Al K already cataloged a lot of this stuff
on bitsavers?
I have seen a lot of ISIS disks archived. But I didn't immediately find a
disk with PL/M 80 and ICE80. Maybe there is.
