  dPMon: 
Cycled Plessey boot to recover from Halle runaway.

  MkIII :
Line driver overload light A on the channel 1 has been lit since starting.
It just went out after flashing for a few minutes.
This condition has been present for a 'long' time at least a year.
We will formulate a plan and then Eric will take corrective action after
we leave.
Sun Feb 27 19:35:38 GMT 1994
  MkIII :
Switched line driver gain on channel 1 from 4 to 2 to eliminate 
clipping in Negative going signal on PGA monitor.  This also turns
off the A LED.
Sun Feb 27 19:51:18 GMT 1994
  dPMon: 
after cycling the analog power for the mkIII there was a run away of the
Objective wheel and the halle filter.  Boot of Plessey stopped run away
of Objective wheel.  Halle filter is also fixed..

  dPMon: 
Wild guiding since we are swapping line drivers on the back of the mkIII.
Sun Feb 27 20:33:41 GMT 1994
  MkIII :
Channel 1 is loud.  With line driver gain of 2 the PGA signal is 3/4
of saturation.  With line driver gain of 4 PGA signal is pegged negative.
Also with a gain of 4 in AM differential driver error light A is lit.
P+S for channel 1 is only slightly less than that for channel 0 with a gain
of 2 on the line driver.  Decision: run at line driver gain off 2.
We will try  to do a cal this AM to compare before to after.
