** 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).
