IBM 701 Computer, LLNL, 1950s

The IBM 701, known as the Defense Calculator while in development, was announced to the public on April 29, 1952, and was IBM's first commercial scientific computer. In June 1954, the first of two IBM 701s arrived at Lawrence Livermore National Laboratory The IBM 701 had a 4,096-word memory, each word being 36-bits; equivalent to almost 12 decimal digits. The parallel feature meant the machine did most of its internal operations including arithmetical on whole words and much faster than the Lab's UNIVAC. According to computation pioneer George Michael, however, the machine "freely made mistakes, but never reported them." Input for the 701 was prepared on a keypunch and entered through a card reader. No photographer credited, circa 1950s.
