The UNIVAC Solid State was a magnetic drum-based solid-state computer announced by Sperry Rand in December 1958 as a response to the IBM 650.It was one of the first [1] [2] [citation needed] computers offered for sale to be (nearly) entirely solid-state, using 700 transistors, and 3000 magnetic amplifiers (FERRACTOR) for primary logic, and 20 vacuum tubes largely for power control.
The UNIVAC Solid State was a 2-address, decimal computer, with memory on a rotating drum with 5,000 signed 10-digit words, aimed at the general-purpose business market. It came in two versions: the Solid State 80 (IBM-Hollerith 80-column cards) and the Solid State 90 (Remington-Rand 90-column cards).

The UNIVAC 1107 was the first solid-state member of Sperry Univac's UNIVAC 1100 series of computers, introduced in October 1962. It was also known as the Thin-Film Computer because of its use of thin-film memory for its register storage. It represented a marked change of architecture: unlike previous models, it was not a strict two-address ...
Used solid-state diode circuits for its logic. Several computers were based on the SEAC design. SWAC: 1950 1 Built for the U.S.'s National Bureau of Standards, it had 2,300 vacuum tubes. It had 256 words (each 37 bits) of memory, using Williams tubes: ERA Atlas: 1950 (Military version of Univac 1101) Used 2,700 vacuum tubes for its logic ...

The UNIVAC 1103 or ERA 1103, a successor to the UNIVAC 1101, [1] is a computer system designed by Engineering Research Associates and built by the Remington Rand corporation in October 1953. It was the first computer for which Seymour Cray was credited with design work.
This is a list of transistorized computers, which were digital computers that used discrete transistors as their primary logic elements. Discrete transistors were a feature of logic design for computers from about 1960, when reliable transistors became economically available, until monolithic integrated circuits displaced them in the 1970s.
