This discussion is great.  I was so hoping Steve Bjork's Coco4 project would 
work, and was disappointed when it was abandoned.  If we do come up with a 
"better" Coco, please do not forget the old semi-graphics modes.  Many 
really great software programs were written for these old graphics modes, 
such as Mark Data's Cave Hunter.
