Some said they have CDOS and Cromemco disks

Hmm. I have here a Maynard "Sandstar" controller with a NEC D765AC and
some special software called "JFORMAT-2" which has parameterized disk
tables. It handles 8" single density 3740, so it ought to be able to
handle this single density as well so I could format, yes?
(I also have a couple of real IBM PC's I can throw it into).
If so, then presumably I could format some disks (I have some disks I had
for my old Atari 800 that I expect would work), and get the rest from Mr.
Dunfield, yes? [I'd need to know where to download that stuff from...]
