In 1954 IBM announced the 704 Data Processing System. Though the company did not designate it as a computer, it was the first commercially available computer to incorporate indexing and floating point arithmetic as standard features. The 704 also featured a magnetic core memory, far more reliable than its predecessors’ cathode ray tube memories. A commercial success, IBM produced one hundred twenty-three 704s between 1955 and 1960.
