[Coco] Retro computer, somewhat similar to CC1/MC-10.

I would think that the microcontroller was something like a PIC, SX or that 
type of microcontroller. The heart of the board is the ezVGA chip. With its 
cost of $25 and some comments I have researched this may very well be a 
Xilinx XC9500 series CPLD. A simple VGA willfit in a Xilinx XC9572 and 
with memoryinterface you would need at least a 84 pin PLCC package that 
they do come in.
