When Simcart (missile simulator cart) is being run, it is pad checkout - a good checkout if you are really on it and no one makes a mistake can be done in 2 - 2 1/2 days. More than that you are having problems. There were times when debugging is takes longer than usual. Problems being identified could be due to a broken wire, or a change in the logic with a wire put on the wrong terminal. Brian was the "orchestra director" for debugging. The skids are looked at by the logic sequence. Terminal boards were housed in the cabinets of 5 terminal boards and 72 connections per cabinet. It was all hardware - no software. You had to trace the wiring back to where the pressure switch came in and where it went. Sometimes the wiring was transposed. Brian was suppose to direct the technicians of where CDU [cable distribution unit] went due to a change in "logic". Or someone might have stuck the wire in the wrong spot. Then you would need to find the problem and change it appropriately. [Mary and Linda were 2 wiring technicians who had a soft place in their hearts for Andrew.]
