Static RAM on Cartridge

One area which peaked my interest is the idea of adding more memory. I was excited about the idea of going beyond that 72 K boundry. I was not quite ready to take a jump an add a full 64 K, but a leap to 16 K, maybe. I had one of John Oliger’s User Cartridge Boards with no eproms and no way to program my own. I noticed that the price of 8 K by 8 static rams were down to a reasonable price. So, with John’s board in hand, I set out to find a way to interface them to my 2068.
