    ** Summary of DAQ problems:
    Last night ~18:00 "busy" from E-arm stuck (halog 47086).
    Next a TDC on H-arm went bad (halog 47097,98,99)
    perhaps as a result of cycling the crate power.
    The replacement TDC had suspicous data but we
    think we can live with it. However, we will try to
    replace it Monday during day shift (halog 47119,122,123,137,140).
