Changes

The 74" 1.9m telescope control system (TCS ) is written in C , using XFORMS to create the Graphical User Interface (GUI). The software runs on a PC running real-time linux.  The TCS allows the control of the telescope; the acquisition and guiding (A/G) camera; and the dome (including opening and closing of the shutters , and control of the windblind, as of December 2009and flatfield lamps). <!--As of May 2016, the TCS allows powering and slewing of the telescope.-->Upgrades are currently in progress that require a new TCS PC (tcs74v4) to be used when SpUpNIC is mounted, and the earlier version (tcs74v3) with HiPPo and SHOC.
