Well, you wouldn't have to hack the BIOS but (assuming you're running CDOS)
you'd need a 5 1/4 CDOS image; I think Dave D has some on his site.
Good to know.

16FDC sounds right but this takes us back to the original topic: that DB-25
is the RS-232 console port, not a printer.
I seem to remember a whole bunch of DB25 cutouts in the rear panel of that
machine...
it's
sometimes convenient to hook up a known good 5 1/4 drive to check
out the rest of the system and get it up & running before you dig into
the 8". Also makes it easier to make disks from PC images if you need
them.
It's been a really long time since I played with it, but I remember the
rest of the system working okay, more or less. There's a CPU board and
a 64K RAM board in there, besides the FDC (which if I'm remembering
right also has the printer port on it). Does 16FDC sound right? If there's no HD you might have trouble finding
12V though & need a
separate supply or regulator; an external powered 5 1/4 disk in a nice
enclosure is a useful peripheral for a System3.
I suppose I could rig one up, but I don't know about hacking together a
BIOS for that machine. I never did get into that stuff all that much. Good luck.
Speaking of which, I just discovered handy a loose-leaf binder
labeled "Cromemco Systems Documentation" which has everything I might
possibly need in there, including data on all the cards, the drive, and so
forth, including schematics and other pertinent technical details. Wouldn't
it be nice to get that sort of info with other stuff! :-)
