[Coco] FW: Multi-Processor 6809 Computer System

Mon Apr 29 09:40:52 EDT 2013

The Fujitsu FM-7 computer uses 2 6809 being on of them for generating
graphics. There is no vdp on this computer, the second 6809 is used
exclusively for generating 8 color 640x200 pixels graphics.

Some dual 6809 arcades do the same.
