Quoted from o-din:The rom in question is the IC17 flipper rom which uses a 2532, all the rest are 2716s, is there a difference? This is a Black Knight system 7. Where would be the best source for a replacement?
2716 is a 16K rom. 2532 is a 32K rom (with a slightly different pin out).
You can get new ROMs here.

Beware the during the time of jungle lord and black knight, WMS mislabeled two of the rom IC## designations. So when replacing the ROM ICs, use the drawing the MPU from a sys 7 manual to place your new ROMs. The new replacement ROMs will be labeled properly and match the drawing in the manuals.
