    [Electrical] 250 with bad EEPROM and error C2654

    Hello there, guys and girls.

    I've got a 250 with a problem which, after a lot of troubleshooting, forum reading and parts swapping with another machine, boiled down to a bad EEPROM - the little one on the PWB-A.

    Trouble is, I couldn't find a part number for that eeprom so I went and bought a clean identical one at an electronic boutique, but the machine apparently doesn't like it, because it throws a C2654 error, which the manuals claims - quite rightly - that it's because the EEPROM is empty.

    Now, is it possible that:

    - There's a part number for that eeprom that I don't know of?
    - I can make the machine work with a new eeprom somehow?
    - What the heck can I do to correct this?

    Cheers!

          Can you - or someone else - provide me the pn?
