Is it possible to use a 27C512 eeprom in the ROM Expansion Card? I have some of them and I was wondering if I could use them here. Thanks!

Hi,

If you are using ROM board v1.0, it is compatible with 27C512.

If you are using ROM board v1.2, you won't be able to use the 27C512 directly, but I think you can do some jumper work on the board to adapt the 27C512 chips.

Thanks,

Liu

I’m using the ROM board v1.2 so I prefer to order some 27C256 then. Thanks Liu!
