Hardware Description

The AN/UYK-20 "Data Processing Set" was a ruggedized small computer manufactured by Univac and used by the United States Navy for small and medium-sized shipboard and shore systems built in the 1970s. It featured non-volatile magnetic core memory and was housed in a heavy-duty metal cube-shaped box which was designed to fit through a 25-inch circular hatch. In 1972, in response to the proliferation of small computer types in the Navy's inventory, the Chief of Naval Material mandated the use of the AN/UYK-20(V) in systems requiring a small digital processor.
