[Coco] Re: [Color Computer] Building an embedded OS9 system from CoCo OS9

[jimcox at miba51.com]

While I agree with Bruces reply to Mike that the PIC would 
be cheaper and is better supported, it might not be as 
much fun for Mike.

As for embedded systems, wouldn't all the 6809 based 
arcade systems count?  Is there online documentation for 
those systems, and if so, could information be gathered 
from them?
I'm not suggesting that a person copy the boards (wouldn't 
be of any use for mobile applications any ways) but you 
could get some ideas from them.  I know of one person I 
referred to this list that was developing a VHDL version 
of the 6809 for a HAM application.  I don't think he was 
prepared to market the chip or boards due to time 
contraints.
