[Coco] Embedded CoCo

Thanks for the input.
I think what most of us envisioned was not an expansion board 
for the coco, but a small(physically) embedded 6809 board 
similar to coco. We then could use a real coco to develop 
software/firmware in Rom/Prom/Eprom and then plug that chip 
into the "Mini-Coco". Also we could use a real fullsize board 
coco motherboard with keyboard removed as a testing version 
of the embedded one until programming is complete befor we 
transfer to the "Mini-Coco".

Flash-prom? Yes Yes Yes!!
An 8k byte Flash Bios in the "mini-Coco".
It would be "really cool" to be able to Flash the bios and 
also to Change the decoding scheme in the address decoder 
PLD. Isn't that what "Field Programmable" means?

How about an expansion area for additional PIA's and/or 
PPI's, VIA's etc..

Keep those ideas coming.
