 I seem to remember a whole bunch of DB25 cutouts in the
rear panel of that 
machine... 
For the real printer port(s) and extra RS-232 ports for I/O or multi-users.

 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!  :-) 
Cromemco were one of the most professional of the computer makers of the
day and sold many systems to labs, educational and government users, especially
the army, navy & air force, and a big multi-box installation at the NYSE IIRC; 
mind you, their prices reflected that...

Also one of the few who, at least in name, are still around...
