Description
The UNIVAC Solid State was a 2-address, bi-quinary coded decimal computer, with memory on a rotating drum with 5000 signed 10 digit words, spinning at 17,667 RPM in a helium atmosphere. It was 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 (Remington-Rand 90 column cards).
