Tom Sargent:
     1. I added a correction for up/down focus position to the 
        pointing model. The up/down displacement is presently set by a 
        manual command.
     2. I implemented slew messages to the inclinometer task (which 
        doesn't exist yet).
     3. At the SMT we noticed the A/Ds reading the encoders had one 
        channel become very noisy on 2 different occasions.  The A/Ds 
        had to be power cycled to fix the problem.
     4. We started having problems with servo apparently not servicing 
        the DSP often enough. It is as though Linux gets busy and 
        doesn't allow the servo program to run, or the servo program 
        gets busy doing something else and can't keep up.  I spent a 
        couple days st the SMT looking for an explanation of this 
        without any success.  A few diagnostics were added to servo 
        and to the DSP code.

Pete Hubbard:
     1. Received parts for cables that are used with Focus drive 
        electronics.
     2. SMT for testing and installing a 100Ms output BNC on the back 
        panel of the Servo computer that will be routed to  the Sam 
        Buss.
     3. Hooking up the signal cables that interface between Tracker 
        chassis and the Sam Bus.
     4. Helped with Sambus channel 28 and 29 problem . Still 
        oscillates at the control room chassis only. Making it the 
        Xmit mode and output at logic "hi" the oscillation is not 
        there.
     5. Helping get the optical telescope ready to mount on SMT.
     6. Building a interface panel for the servo to encoder cables.
     7. Finding all the tools that are needed to make cables for the 
        focus drive.
