Summary

Description Space Shuttle upgraded GPC.jpg	English: The NASA Space Shuttle General Purpose Computer (GPC) IBM AP-101S , 1991. "At 64 pounds, the shuttle's general purpose computers are heavier than several modern desktop machines combined. However, they can operate for years without failing, a reliability mark that is no accident. Engineers spend months making sure any change to a computer or its software is tested repeatedly."
