Anyone happen to have this? It's what the IMP16 board uses, and I'd like to see if I can build an adapter for my programmer to read the data out of the ROMs before I get rid of the boards... (I suspect it's a 3-rail device, but the address and data lines are TTL, so hopefully I can make them appear as 2Kx8 devices* to my programmer) (* The smallest ROM my programmer knows about is a 2716 single-rail device) ta Jules
