Here's the backstory. I'm on a circuit board design kick, and am making up some small diagnostic testing boards for people to use on older machines. Nothing complicated, but useful if you do a lot of repair work.

Now,while I am on this kick, I managed to damage one of those rare PROM chips on my Mom's Firepower. I know I can just modify the board to take a 2732, but I hate doing semi-permanent board modifications...particularly those that require jumper wires.

So I sketched out a design for a plug-in, no solder, no-modification needed conversion board that allows you to use three 2716 EPROMS in place of the three unavailable PROMs.

But I just don't know if this is something people would be interested in.

Thoughts?

When it comes to Gottlieb, you need to buy the chips from PBR either way. IIRC they're the only approved re-seller, and Gottlieb won't allow the ROM files out in the open.

Something worth thinking about though for the future.

Took a suggestion, refined the idea, now it's a much smaller board that only takes a single 2764 EPROM and replaces all 6 of the original PROM/EPROM chips.

Fits into the CPU socket.

Actually, I'm looking to eventually sell the things if it all works out properly.

Will be reviewing the board layout over this weekend, may have a functional prototype end of next week.... maybe.
