     The meeting yesterday on Jim's "Control Box Programming and Description"
was very useful.  Below I summarize some of the key issues. Please send comments 
and corrections. 
      1.) "Who's is charge"?  I am worried about who has control, especially
at first when there is no computer interface. I would suggest for manual control, a two
position switch.  When enabled, manual control is in charge, when disabled, it is
completely disabled.  However, it is too late to modify the present control box since
it is to be shipped in one week. This modification might be considered for the 2nd
control box. However, if the first control box works as is, then this modification is 
not really necessary.
      2.)Manual and USTC operation must be tested completely with the final 
control box assembly.  Is the temperature readout not operational at this time?
      3.) We need to contact USTC to see if they can supply the USTC control 
signal requested by Jim.
      4.) We need to generate a DAQ trigger for use when running under PC 
control.  We need to contact USTC about the specifics of the USTC DAQ trigger so ours 
will be similar.
      5.) We want to readout the control box Xilinx board for two cases: slow
monitoring (say once per hour) and after laser firing (say once per day but multiple 
times).  The first would be done under the slow control monitoring; the second would
 be by the TOF monitoring software.  We need to learn more about the monitoring 
 software and data bases.  How do we get hold of the TOF data?
      6.) The control box does not read the PS voltages.  To make it easier 
to check these voltages, it would be useful to have them available on the front panel.
Maybe control box 2?
      7.)  We need a contact at IHEP, who can update the control box firmware
and software if necessary.
      8.) According to Andrew there may be a lack of memory available on the 
Xilinix for the program and firmware
      9.)  We plan now to ship on the 9th.  Marc will need help with packing.
