  Several miscellaneous interfaces have been implemented into the system, or are planned. Parallel interfaces are used in several places, such as to communicate with the 140 ft. telescope for servo control system testing. A raw encoder parallel readout will be implemented to allow a redundant check of the contractor supplied servo system outputs. Analog I/O points are provided to complete the interfacing of the computers.
