    z80 cpu alarm and any panel button (such as F1, F2) no response

    The Hitachi seiki HC 400 had z80 cpu alarm firstly.

    Now realized its pannel buttons no working now.
    Does it mean the operation pannel faulty too?

    Does anyone know if it can be caused by the z80 cpu alarm?

    Thanks,
    Bob

    It can either be your micon board is faulty or possibly a bad ladder due to corruption or low battery
