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.
This is a list of UNIVAC products. It ends in 1986, the year that Sperry Corporation merged with Burroughs Corporation to form Unisys as a result of a hostile takeover bid [ 1 ] launched by Burrough's CEO W. Michael Blumenthal.
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 ...

The UNIVAC 1103A or Univac Scientific is an upgraded version introduced in March 1956. [8] [9] [1] [page needed] Significant new features on the 1103A were its magnetic-core memory and the addition of interrupts to the processor. [10] The UNIVAC 1103A had up to 12,288 words of 36-bit magnetic core memory, in one to three banks of 4,096 words each.
An ERA drum was the internal memory for the ATLAS-I computer delivered to the U.S. Navy in October 1950 and later sold commercially as the ERA 1101 and UNIVAC 1101. Through mergers , ERA became a division of UNIVAC shipping the Series 1100 drum as a part of the UNIVAC File Computer in 1956; each drum stored 180,000 6-bit characters (135 kilobytes).
VS/9 was controlled by a computer operator at the central site. Computer operators interacted with the system through a system console. Initially, this console was a teletype device, but was later upgraded to a video display device with an attached system console printer. All system console messages were logged to the system console printer.
