[Coco] Blank PCB for EPROM-Based Cartridge

[Bruce W. Calkins]

That looks just about how I would do it.  I would probably not bother 
supporting the 2732 though and just have 1 socket for the EPROM.  You might 
consider another jumper or two to support 4k, 8k and 16k banks.  There were 
a very few CoCo ROM pack games larger than 16k, but they used fancy bank 
switching modes that might be hard to reproduce.
