HP 1000 diag library on 7900A disc

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)
