The IBM System/360 Model 75 is a discontinued high end/high performance system that was introduced on April 22, 1965. Although it played many roles in IBM's System/360 lineup, it accounted for a small fraction of a percent of the 360 systems sold. Five Model 75 computers housed at NASA's Real Time Computer Complex were used during the Apollo program.
