that did diskette bit-copies. Even better, if I could find a utility to
read the diskette and store it to some sort of image file that I could burn
onto CD, I could restore the software to diskette later.
What do you know about the disk format? FM v MFM? Bytes per
sector? Sectors per track?
IFF it is MFM, then is is POSSIBLE to duplicate it using a PC plus
appropriate software. Otherwise it will require significant hardware,
such as Central point option board, Catweasel, etc.
I have a Victor 9000 system in the computer barn with
a 5.25" drive. I
believe it's in running condition, though I haven't fired it up since I got
it. IIRC, it runs some early version of MS-DOS or possibly CP/M. Then
again, I think the Victor did some weird stuff with the diskette drive
speed to increase the amount of data it could write to a diskette.
also GCR and 96

If you want to try to copy Victor diskettes on a PC, FERGET IT!
If you want to copy Victor 9000 diskettes, do it on a Victor. NOTHING
ELSE.
There was one being offered on this list yesterday, by Gordon Zaft?
Hmm, I'm sure I can track down a box with a pair
of 5.25" drives.
for what?
