The UNIVAC 1004 was a plug-board programmed punched-card data processing system, introduced in 1962 by UNIVAC. Total memory was 961 characters (6 bits per character) of core memory . Peripherals were a card reader (400 cards/minute), a card punch (200 cards/minute) using proprietary 90-column, round-hole cards or IBM-compatible, 80-column cards ...
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 I at Case was still operable in 1965 but had been supplanted by a UNIVAC 1107. [citation needed] A few UNIVAC I systems stayed in service long after they were made obsolete by advancing technology. The Census Bureau used its two systems until 1963, amounting to 12 and 9 years of service, respectively.
An upgraded 1106 was called the UNIVAC 1100/10. In this new naming convention, the final digit represented the number of CPUs or CAUs in the system, so that, for example, a two-processor 1100/10 system was designated an 1100/12. An upgraded 1108 was called the UNIVAC 1100/20. An upgraded 1110 was released as the UNIVAC 1100/40.
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.

Mounted in a trailer van, making it the first computer to be transportable. WISC: 1954 1 Built by the University of Wisconsin–Madison: REAC 400 (C-400) [12] 1955 [13]
The UNIVAC 9000 series (9200, 9300, 9400, 9700) is a discontinued line of computers introduced by Sperry Rand in the mid-1960s to compete with the low end of the IBM System/360 series.
VS/9 is a computer operating system for the UNIVAC Series 90 mainframes (90/60, 90/70, and 90/80), used during the late 1960s through 1980s. The 90/60 and 90/70 were repackaged Univac 9700 computers.
