    keyword=scaler moved to Compton FADC crate

    The CAEN scaler that was at the far right of the formerly used
    MWPC DAQ in the lower VME crate was moved to the Compton FADC crate,
    with Brad's permission.

    The scaler appears in the datastream with header dae56000 and is
    at the end of the regular scaler bank. It looks like the analyzer
    does not get confused by this.

    The 40 MHz clock is in the 4th channel and tracks the other scaler.
    I did not touch the other scaler. It has been working all after-
    noon since the power-cycle / re-seating.

    Now there is a new disease: The FADC crate constantly reports
    interrupt: FADC not busy state= 1

    I suppose something got unplugged. Will check tomorrow.
