Added Steps to reproduce. It's not necessary to change the difficulty - just choosing Save and Exit is enough.

The PCB has a 59C11 which is not the same as ER5911.

I traced this back February 22/23, 2023 changes starting where both EMUDEV and 68000 cpu series changes took place.

The error message comes from src/devices/machine/eepromser.cpp

Perhaps the eeprom isn't hooked up correctly.
