[Coco] [color computer] Just imagining...

[Leonard Miller]

Isn't there a computer that has two processors on it?  I think it is a
fujitsu (spelling?) or something like that.  I often wondered if anybody
ever ran os9 on that.

Understood, but I was thinking of one CPU to handle the OS, and then 
driver-level stuff to offload to the others. One CPU could handle all 
the graphics, one could be configured as a DMA or handle I/O. I've done 
some preliminary feasability studies on the idea, and with some sub-50ns 
SRAM or SDRAM it just might work...
