Anyone know about these? It's about 5.75" X 6.75", with a 100 position (50 each side) card-edge connector, and ejection levers on the front. 64K ram, 1x 2716 EPROM with a handwritten label `Satrom 0942 24 Mar 81' over the window. A little googling reveals that 20002 is the zip code for DC and not much else so far. :( Thanks! Bob
