content: The IBM 702 was one of the first electronic computers built by IBM for its business customers (the earlier IBM 701 was designed primarily for scientific calculations. The earlier IBM 650 was directed at business, more popular, but less powerful). The IBM 702 was announced in 1953, with deliveries to begin in 1955. Machines delivered in 1955 had cathode ray tube memories, but this provided maintenance difficulties and magnetic core memories replaced these on both installed IBM 702s and those sold in 1956. A successor machine, the IBM 704, quickly replaced it, and sold from 1955 until 1960. Some fourteen examples of the IBM 702 were made, this one went to the Monsanto Chemical Company in St. Louis, Missouri.
