High Quality Content by WIKIPEDIA articles! The AN/FSQ-7 was a computer model developed and built in the 1950s by IBM in partnership with the US Air Force. Fifty-two were built and used for command and control functions for the Semi Automatic Ground Environment (SAGE) air-defense system. An AN/FSQ-7 computer contained 55,000 vacuum tubes, occupied about half an acre (2,000 m ) of floor space, weighed 275 tons, and used up to three megawatts of power. Performance was about 75,000 instructions per second. The fifty-two AN/FSQ-7s remain the largest computers ever built, and will likely hold that record in the future.
