For my personal needs of such a board, it would have to be software compatible 
with the COCO3. First off so that any hardware debugging can be made far easier 
than trying to go off on a tangent. Also where I live I am cramped for space. So 
another PC case and keyboard and monitor is not an ideal situation. Also I want 
some software that I am writing in DECB to work on the new board.

As I stated before size for me is important. I personally am learning towards the 
EPIC and PC104 combination. Where the main portion of the CPU hardware sits 
on a EPIC size board( ~4.5 x 6.5 inches) with the capability of stacking as many 
PC104 boards on top as needed. Can be either 8 or 16 bit ISA buss or use some 
version of our own.
