A question for Chuck, Fred and anyone else with

experience/knowledge: can OSI disks (specifically Challenger 4P disks)
be read by a PC and imaged/recreated ? If so, how? If not, why not?
Don't see 'em in either 22disk or Xenocopy, but then they're not CP/M.
It's a question from a third party and I don't have any disks or I'd
try some imaging programs myself.
The C4P (as well as other members of the Challenger line) uses a 6850
ACIA and some monostables (for data separation) as a disk
controller. The format, data rate, etc. is utterly sui generis.
On the other hand, you could probably build something to read from
these disks fairly simply. There's not much to it.
