I'm wondering if the PCBs out there share any common RAM chips? This board I have some of the RAM chips have some rust on them and will most likly need to replace them so I am hoping that a lot of the PCBs share the same type of RAM chips so I can order them in bulk if I have to.

2114 ram, 4114, 2148, 4164 are pretty common


As far as ram goes, rust is okay might not be pretty but as long as the game works don't waste your money replacing working chips.
