    Hallo Andrew,

    - what are the voltages on the four pins?
    - does the power cord include a transformer?
    - if it uses a transformer, what voltages/current
    does it provide?

    AFAIK you have to feed this drive with 9 VAC and 15 VAC. The 9V is
    used to supply the 5V, the other one to supply the 12V.

    I don't know what pins are used for what. But it isn't that difficult
    to trace things back from the voltageregulators, through the
    rectifiers, towards the pins.

    One possible tip: I thought the MSX SONY HitBit 75 used the same
    powersupply.

    Hi All:

    I have an Amtech RF512C but no power cord. I need some info
    in order to fabricate a new power cord:

    - what are the voltages on the four pins?
    - does the power cord include a transformer?
    - if it uses a transformer, what voltages/current
    does it provide?

    Any info on the RF512C supply would be helpful.

    Thanks for your time,
    Andrew.
