Just curious;
is anybody actually using a Cromemco system
out there, running either CDOS, Cromix or Unix? Or does
anyone at least have one in running condition?
I have an IMSAI chassis stuffed with cromemco boards. I run CP/M
on it... but I don't think there would be a reason it wouldn't run
a cromemco OS. It has a CPUZ, a 16FDC, a 64KZ and a TU-ART in it.

No, unless there are some unusual mods, I'd think that a set of
Cromemco boards would run a Cromemco OS just fine. BTW, I
assume you mean a ZPU? I'd be interested in knowing how you got CP/M onto
the Cromix
diskettes and configured for its memory model?
The hard way (and the fun way)! I wrote my own CBIOS, bootstrap,
and a program to format a diskette, cross-compiled on a modern intel
box, wrote a program to massage the compiler output into a text stream
that the ROM monitor on the 16FDC would like and then used the monitor
to run the formatter. Finally, pumped over the bootstrap, CP/M and
my CBIOS and used the sector write facility of the 16FDC ROM to write
the whole thing to a diskette a sector at a time. It was very gratifying
when the sucker booted up the first time.
TM100 drive(s) I assume?
Actually, a pair of SA-851s.
Just wanna swap tales I guess.
Something about the 16FDC doesn't play nice with the IMSAI front panel.
You can't deposit or examine memory with it on the bus. Even with the
schematics, I don't see what the problem is. Do you know a solution by
any chance?
