Where the work was done: TBD
What we accomplished: IBM produced the avionics computer used to control the Space Shuttle and a variety of other aircraft.
Adapted from writeups by NASA and Wikipedia: The AP-101 was a derivative of the 4Pi introduced by IBM in 1966. It used the basic instruction set architecture from IBM's mainframe System/360. The AP-101 processed 480,000 instructions per second. Five AP-101s were installed aboard each shuttle. The AP-101 was also used in a broad set of US military aircraft, including the B-52 and B-1 bombers and the F-15 fighter.
