[Coco] Re: [Color Computer] Re: Complete Commodore 64 home computer on a single chip

John,

If I knew how to do it, I'd do a vhdl memory management unit/dram 
controller along with the 6809 core: something like the MMU in the GIME 
or the MC6829. Then you'd have a cpu with built in MMU that can run 
nitros9 level 2- just add serial ports!

I'd buy 'em... they'd make awesome embedded controllers with a real OS!
