    Citizen M12 " Cannot download NC system" Alarm

    Hi All,

    Has anyone experienced this alarm on their early 2000 model L or M machines?

    The machine's control simply shut off on me while in a power on state(but not running). When I try cycling power back on, I always get this message and can't go any further.
    I talked to a Citizen tech and he said its a 50/50 chance it could be either the hard drive(or cable) or mother board. He told me 1st to get the hard drive and see if that fixes the problem, but I'm just looking for some other opinions on if anyone experienced this issue first hand before I start emptying my wallet.
    Any feedback would be greatly appreciated.
