Tom Sargent:
     1. With Bill's help I seem to have the pointing working just like 
        the old control system. I checks a grid of about 20 points 
        across the sky and the agreement is generally to within 0.01 
        arcsec.
     2. I wrote a function to decelerate the telescope to a stop while 
        keeping it on the sun avoidance path.  It has been inserted 
        into the servo program and is being debugged now. This will be 
        used if the operator switches to a different object while the 
        telescope is following a sun avoidance path. When it gets to 0 
        velocity, it will start on the path to the new object. 
     3. Servo now writes out a file once every 3 minutes which 
        describes the sun avoidance zone in AZ-EL. Catalog has been 
        changed to read this in and display the actual sun avoidance 
        zone. 
     4. Servo has been altered to send an "at source" message to 
        monitor and catalog when it finishes a slew.

     1. Received samples from TI, SN74HCT157 mux chip and SN74ABT2244 
        octal buffer with series resistor on the output. This will 
        help with ringing in the output ribbon cables driving the 
        counter chips AM9513.
     2. Looked at logic families ACT, ABT, BCT, LVC and LV-A. Only ABT 
        and HCT have proper logic compatibility to drive the AM9513 
        counter chips.

Lori Warner:
     1. Learning some gtk. Root installed the necessary config file 
        this morning so I can compile. Going through the on line 
        tutorial.
     2. Brought in a spare (personal) computer to learn how to install 
        Linux.
     3. Using two GTK+ and GDK books to gain skills.

Dave Ashby:
     1. No Report.
