 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? 
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 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. 
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 luck.
