Jay,
Do you have the ability to make a raw sector dump of a 7900A disc cartridge
to a file that can be read by a PC? I'm not sure how that would work, maybe
dump the 7900A disc cartridge to 9-track tape and read the tape with a PC
compatible tape drive, or something like that? I seem to recall seeing some
HP 1000 disk image files that were 20MB or so on the web somewhere but can't
find them now, so I think this can be done.
Anyway, if you could dump the HP 1000 diag library 7900A disc to a PC
readable file, I think the individual diagnostic images could probably be
extracted from it. If I read the diag manual right they should just be
saved on disk in standard absolue binary format, but with a three word
header which forms a linked list to the cyl/head/sector of the next diag
image in the list. (This is from the Diagnostic Configurator reference
manual, p/n 02100-90157)

I have the complete HP diag library on 7900A disc cartridge. I can copy it
to another 7900A disc cartridge, but then of course you have to have a
7900A
drive to read it. I don't think the disc based diags can be copied to mag
tape or paper tape, I seem to recall the diag manual saying this wasn't
possible due to different formats. IF I've got it backwards (tape to disc
vs. disc to tape), then it can be done but only if you boot up DOS or RTE
first and use it to do the copies.
