II design. It proved too much for MIT's resources, resulting in IBM being retained as prime contractor – though the MIT Lincoln Laboratory Division 6 still participated in AN/FSQ-7 development. Similar to the Q7, the smaller AN/FSQ-8 Combat Control Central was produced without an Automatic Initiation Area Discriminator and other equipment. A simplex version of the AN/FSQ-7 was located at the premises of the System Development Corporation in Santa Monica, California from 1957 until the premises were vacated some time after 1981. Uses SAGE The experimental SAGE subsector, located in Lexington, Massachusetts, was completed in 1955, equipped with a prototype AN/FSQ-7 known as XD-1 in Building F. The third evaluation run with the XD-1 was in August and the prototype was complete in October 1955, except for displays. DC-1 at McGuire Air Force Base was the first operational site of the AN/FSQ-7 with consoles scheduled for delivery Aug–Oct 1956. Groundbreaking at McChord Air Force Base was in 1957 where the "electronic brain" began arriving in November 1958. The Cape Canaveral BOMARC 624-XY1's intercept of a target drone in August 1958 used the Kingston, New York, Q7 1500 miles away. By 1959, the 2000th simulated BOMARC intercept had been completed by the Q7. The SAGE/Missile Master test program conducted large-scale field testing of the ATABE mathematical model using radar tracks of actual Strategic Air Command and Air Defense Command aircraft conducting mock penetrations into defense sectors (cf. Operation Skyshield). The vacuum-tube SAGE network was completed (and obsolete) in 1963, and a system ergonomic test was performed at Luke Air Force Base in 1964. According to Harold Sackman, it "showed conclusively that the wrong timing of human and technical operations was leading to frequent truncation of the flight path tracking system." Back-Up Interceptor Control Systems (BUIC) were used to replace the AN/FSQ-7s: two remained at SAGE sites until 1983 including McChord AFB, and the Q7 at Luke AFB was demolished in February 1984. Sabre The SABRE airline reservation system used AN/FSQ-7 technology. In popular media Q7 components were used as props in numerous films and television series needing futuristic-looking computers, despite the fact they were built in the 1950s. Q7 components were used in The Time Tunnel, The Towering Inferno, Logan's Run, WarGames, Independence Day, Planet of the Apes TV series (Season 1, Episode 5, "The Legacy" aired October 1974), and many others. Today The Computer History Museum displays several AN/FSQ-7 components.
