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.
