It seems that my first microprocessor textbook had the complete schematics
and programs for a 6800-based terminal, including a 6845-based video interface.
I've never built it, but I do remember looking through the chapters on 68xx
peripheral chips, and most had fairly complete discussions on how to use
them: the 6821 PIA (Peripheral Interface A(dapter?)), the 6845 (I think),
and others.  

The book is at home, but its title was something like __Using Microprocessors 
and Microcontrollers: the Motorola 6800__, or something like that.  If the
book is of interest to anyone, I can check on it when I get home.

Hope this helps,	-Bill
