First Computer to Incorporate Indexing & Floating Point Arithmetic (1954)

In 1954 IBM announced the 704. 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.
