But which 8-bit?
    I would prefer the 6809 (which means, Color Computer).  The chip is a
 dream to program for, and with OS-9 (or a derivative) it would almost be
 like Unix on a chip (not quite, but close enough).  Give it the graphics of
 the Commodore and you might have a winner on your hands. 
I thought the Japanese had a similar computer. I am not sure if was 6809
or 68000. But when you think about it, you need lots of memory
for 3D graphics, and 16 bit addressing does not cut it.
