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...]
