** UNIVAC 1103, also known as the Atlas II

Some early computers in the USA also used the Williams tube, including the IAS machine ( originally designed for Selectron tube memory ), the UNIVAC 1103, Whirlwind, IBM 701, IBM 702 and the Standards Western Automatic Computer ( SWAC ).

* October – The UNIVAC 1103 is the first commercial computer to use random access memory.

Atlas II, slightly modified became the ERA 1103, while a more heavily modified version with core memory and floating point math support became the UNIVAC 1103A.

The commercial version then became the UNIVAC 1103.

Remington Rand announced the UNIVAC 1103 in February 1953.

Computers with 36-bit words included the MIT Lincoln Laboratory TX-2, the IBM 701 / 704 / 709 / 7090 / 7094, the UNIVAC 1103 / 1103A / 1105 / 1100 / 2200, the General Electric GE-600 / Honeywell 6000, the Digital Equipment Corporation PDP-6 / PDP-10 ( as used in the DECsystem-10 / DECSYSTEM-20 ), and the Symbolics 3600 series.

In the process of merging the companies, the ERA division was folded into Sperry's UNIVAC division.

However, one major project was moved from UNIVAC to ERA, the UNIVAC II project, which led to lengthy delays and upsets to nearly everyone involved.

In 1953 or 1954 Remington Rand merged their Norwalk tabulating machine division, the ERA " scientific " computer division, and the UNIVAC " business " computer division into a single division under the UNIVAC name.

The UNIVAC 1101, or ERA 1101, was a computer system designed by Engineering Research Associates ( ERA ) and built by the Remington Rand corporation in the 1950s.

Although ERA and UNIVAC were run separately within the company, looking to cash in on the UNIVAC's well known name, they renamed the machine to become the " UNIVAC 1101 ".

The UNIVAC 1102 or ERA 1102 was designed by Engineering Research Associates for the United States Air Force's Arnold Engineering Development Center in Tullahoma, Tennessee in response to a request for proposal issued in 1950.

In the years before successor models of the UNIVAC I appeared, the machine was simply known as " the UNIVAC ".

* The UNIVAC 494 was a 30-bit word machine and successor to the UNIVAC 490 / 492 with faster CPU and 131K ( later 262K ) core memory.

The successor machine was the UNIVAC 1103A or Univac Scientific, which improved upon the design by replacing the unreliable Williams tube memory with magnetic core memory, adding hardware floating point instructions, and a hardware interrupt feature.

( In the years before successor models of the UNIVAC I appeared, the machine was simply known as " the UNIVAC ".

The direct successor to the UNIVAC 1100 is the Unisys 2200 series computers, which use Fieldata to this day ( although ASCII is now also common with each character encoded in 1 / 4 of a word, or 9 bits ).

The EDVAC was the ENIAC successor ( first working in 1949 ), designed by the team who then marketed the UNIVAC.

* UNIVAC 1101, also known as the Atlas

Trochotrons were used in the UNIVAC 1101 computer, as well as in clocks and frequency counters.

The 1102 was a variant of the UNIVAC 1101, using its 24-bit word and a smaller ( only 8, 192 words ) drum memory.

Even before the completion of the Atlas ( UNIVAC 1101 ), the Navy asked Engineering Research Associates to design a more powerful machine.

Burroughs was one of the eight major United States computer companies ( with IBM, the largest, Honeywell, NCR Corporation, Control Data Corporation, General Electric, RCA and UNIVAC ) through most of the 1960s.

The group of manufacturers was first known as " IBM and the Seven Dwarfs ": IBM, Burroughs, UNIVAC, NCR, Control Data, Honeywell, General Electric and RCA.

Shrinking demand and tough competition started a shakeout in the market in the early 1970s — RCA sold out to UNIVAC and GE also left ; in the 1980s Honeywell was bought out by Bull ; UNIVAC became a division of Sperry, which later merged with Burroughs to form Unisys Corporation in 1986.

Magnetic tape was first used to record computer data in 1951 on the Eckert-Mauchly UNIVAC I.

The company was sold in 1975 to Sperry UNIVAC, while Saab retained its flight computer development.

were sold to what was then UNIVAC to become the UNIVAC 90 / 60 and later releases.

Kristen Nygaard was invited to UNIVAC late May 1962 in connection with the marketing of their new UNIVAC 1107 computer.

The implementation was based on the UNIVAC ALGOL 60 compiler.

SIMULA I was fully operational on the UNIVAC 1107 by January 1965.

Although the term " Unicode " had previously been used for other purposes, such as the name of a programming language developed for the UNIVAC in the late 1950s, and most notably a universal telegraphic phrase-book that was first published in 1889, Becker may not have been aware of these earlier usages, and he explained that " he name ' Unicode ' is intended to suggest a unique, unified, universal encoding ".

In the mid-1960s MAD was ported at the University of Maryland to the UNIVAC 1108.

A UNIVAC I computer was accepted by the Bureau in 1951.

CDC was one of the nine major United States computer companies through most of the 1960s ; the others were IBM, Burroughs Corporation, DEC, NCR, General Electric, Honeywell, RCA, and UNIVAC.

The A-0 system ( Arithmetic Language version 0 ), written by Grace Hopper in 1951 and 1952 for the UNIVAC I, was the first compiler ever developed for an electronic computer.

The A-2 system was developed at the UNIVAC division of Remington Rand in 1953 and released to customers by the end of that year.

ARITH-MATIC was originally known as A-3, but was renamed by the marketing department of Remington Rand UNIVAC.

In 1975, the D23 system was seriously delayed and the solution was a joint company with Sperry UNIVAC.
