The IBM 702 was an early generation tube-based digital computer produced by IBM in the early to mid-1950s. It was the company's response to Remington Rand's UNIVAC, which was the first mainframe computer to use magnetic tapes. As these machines were aimed at the business market, they lacked the leading-edge computational power of the IBM 701 and ERA 1103, which were favored for scientific computing,[1] weather forecasting, the aircraft industry, and the military and intelligence communities.
Within IBM, the 702 was notable for adapting the new technology of magnetic-core memory for random-access applications.
The 702 was announced September 25, 1953, and withdrawn[2] October 1, 1954, but the first production model was not installed until July 1955.[3][4] It was superseded by the IBM 705.
