I've been working on some new hardware for the classic Bally/Stern system and I made up some boards to move the ROM from the original sockets to a daughter board that plugs into J5 on the MPU. The daughter board accepts 2 2732 EPROMs. This is a proof of concept for a future design which will use a single 2764 EPROM and move the 5101 RAM to the daughter board in NVRAM. I probably won't make any more of this version so get them while they're hot... and cheap. I have 4 available. Your choice of game code. $30 each. Shipped.
Caveat: MPU100 and Bally -17 MPUs don't have A14 connected to J5. This means that you can only use ROMs intended for MPU100 or -17 MPUs on those boards. I could have fixed this but like I said... it's a proof of concept design.
The ideal use for these boards (IMO) is for use with Leon's test ROM.
Who wants one?
