hi,
if you are interested, I have 2 project of elektor of emulator for 27c256 eprom with RS232 control, and a simple 27c256 emulator (with a GAL16V8 mcu)

The design from Elektor is posted somewhere in MCU fileman :wink: . It have some mistakes in schematics, but PCB is OK. **broken link removed** It is only emulates 27C256.
