...

  Everything on it is TTL except for one LSI IC
marked
 MCH-01. Anyone know what that might be?  
 Probably a character ROM. 
How many pins does it have? Character generator ROMs tend to be 24 pin (or 
maybe 28 pin). Is the 'MCH-01' marking a stuck-on label or marked 
directly on the package?

I am suprised there's no RAM on this board, actually. That could be 16 
pin packages, and thus mistaken for TTL.
