Looking Left then Right, we see the North and south pier. Remember the black box on the outside of the dome? There is the radio on the North pier. The "control" computer is mounted on the South pier and connected to the "catalog" computer next to the North pier via an underground RS-232 cable. The software in the control computer was custom written in C and portions of the ConTroL for Astronomy Command Language (CTLACL) are copyrighted by Warren Walker (a club member), The Warren Rupp Observatory and Merlin Controls Corp.
