The UNIVAC Solid State was a 2-address, bi-quinary coded decimal computer, with memory on a rotating drum, announced by Sperry Rand in December 1958, as a response to the IBM 650. It came in two versions: the Solid State 80 (IBM-style 80 column cards) and the Solid State 90 (UNIVAC-style 90 column cards).

With 20 vacuum tubes, 700 transistors, and 3000 FERRACTOR amplifiers in its CPU, the Solid State was one of the first computers to use solid state components.
