But I thought the problem was that most disk
controllers can't do RX02.
Everybody doesn't have a Catweasel or Cryoflux.
That's right.
Chuck's suggestion would require that somebody who has a
flux-transition device (Catweasel, Kryoflux, Central Point Option
board, etc.) would have to do the sector imaging.
Well, or, . . .
somebody who has an RX02 setup, such as you or Allison, could image
the sectors, instead of copying the files, which might be appropriate
if it turns out that the OS that these were created with is
unavailable. How many operating systems use RX02?
