I’m on my Sabbatical right now, so this request came in at a good time. Though first I have to finish up on some VAX and Alpha systems I’m working on, so as to free up space. That or finish a cleaning project in my office. :-) The cleaning project is needed to finish the VAX/Alpha projects…

I *might* have a DEC Rainbow, or I might have given it away. If I do, I have no idea of its condition. An Apple //e would be another old system with 5.25” drives, but seems more unlikely. I might still have an old Kaypro PC, though it hasn’t been used since ’94 (and there is a good chance it went to LCM).

For a while, Uniform was bundled with some Kaypro models. The Kaypro
HARDWARE can certainly do the MFM double density ones (~200K) with
Uniform, but I don't know ehther it can do the FM single density (~100K)
The Commodore 128 with CP/M should be hardware capable, but I don't know
of any software for it. Did they bundle any disk format conversion
software with it?
DEC Rainbow would be hardware capable, but I don't know what software
there is. There was a program 35 years ago, . . .
Apple2 can NOT do it. Well, unless you have one of the aftermarket
IBM/WD/MFM supporting disk controller boards, such as the Sorrento Valley
PC can normally do it. 360K drive preferred.
Almost anything from 5150 up can do the MFM dounle density.
Dave Dunfield's TESTFDC can tell you whether the hardware can do the FM
XenoCopy used to support the MFM double density Osborne format, but NOT
the FM Single Density.
Chuck implied that 22Disk could do BOTH.
