[Coco] Dual Processors?

Yes dual processors is a possibility. Can NitrOS9 be modifield for dual 
processors? That can better be answered by someone more learned about 
OS9. I would imagine it could. I doubt it would be a high priority item as of 
now. 

The 6809E/6309E do lend themselves to multiprocessors. The hardware is 
a bit tricky to do.
