32K Supercart
#2

The current method leaves a lot to be desired--and a lot of room for error. Springing off from that point this weekend, I've done a layout specifically designed to be used as a 32K Supercart (it gives the user 4 banks of 8K each, switch controlled). Both chips can be socketed, as can the coin cell battery to back up the RAM contents. If there is enough interest in them, I may do a small run of the boards for the community, otherwise, I'll just get a couple of them made for my own uses.

2 chips meaning a E/A grom and a 32K x 8 static ram.
