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.

also GCR and 96 TPI

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?
