The UNIVAC Solid State was a 2-address, decimal computer, with memory on a rotating drum with 5000 signed 10 digit words, aimed at the general purpose business market.

The UNIVAC Solid State was a 2-address, bi-quinary coded decimal computer using signed 10 digit words.

Volume 1, Number 2, December 1992 ( revised 1999 )-The UNIVAC Solid State Computer

Only one large-scale mag amp machine was put into production, the UNIVAC Solid State, but a number of contemporary late-1950's / early-1960s computers used the technology, like the Ferranti Orion and the English Electric KDF9.

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.

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.

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.

UNIVAC, the first computer designed for business applications, had many significant technical advantages such as magnetic tape for mass storage.

This was corrected by adding offline card processing equipment, the UNIVAC Card to Tape converter and the UNIVAC Tape to Card converter, to transfer data between cards and UNIVAC magnetic tapes.

The improvements included magnetic ( non-mercury ) core memory of 2000 to 10000 words, UNISERVO II tape drives which could use either the old UNIVAC I metal tapes or the new PET film tapes, and some circuits that were transistorized ( although it was still a vacuum tube computer ).

Up to 24 I / O channels were available and the system was usually shipped with UNIVAC FH880 or UNIVAC FH432 or FH1782 magnetic drum storage.

FASTRAND was a magnetic drum mass storage system built by Sperry Rand Corporation for their UNIVAC 1100 series and 490 / 494 series computers.

The UNIVAC 1105 had either 8, 192 or 12, 288 words of 36 bit magnetic core memory, in two or three banks of 4, 096 words each.

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.

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.

The IBM 702 was IBM's response to the UNIVAC — the first mainframe computer using magnetic tapes.

A variety of UNIVAC embedded computers, including the first fielded version of the late 1950s, the CP-642A ( AN / USQ-20 ), typically with 30 bit words, 32K words of magnetic core memory, 16 parallel I / O channels ( also 30 bits wide ) connected to radars and other peripherals, and a RISC-like instruction set, were used.

* 1951 – Remington Rand delivers the first UNIVAC I computer to the United States Census Bureau.

After the war, development continued with tube-based computers including, military computers ENIAC and Whirlwind, the Ferranti Mark 1 ( the first commercially available electronic computer ), and UNIVAC I, also available commercially.

* March 31 – Remington Rand delivers the first UNIVAC I computer to the United States Census Bureau.

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

UNIVAC, the first commercial computer manufacturer, produced a series of EXEC operating systems.

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

With John Mauchly he invented the first general-purpose electronic digital computer ( ENIAC ), presented the first course in computing topics ( the Moore School Lectures ), founded the first commercial computer company ( the Eckert – Mauchly Computer Corporation ), and designed the first commercial computer in the U. S., the UNIVAC, which incorporated Eckert's invention of the mercury delay line memory.

John William Mauchly ( August 30, 1907 – January 8, 1980 ) was an American physicist who, along with J. Presper Eckert, designed ENIAC, the first general purpose electronic digital computer, as well as EDVAC, BINAC and UNIVAC I, the first commercial computer made in the United States.

His experience with programming the ENIAC and its successors led him to create Short Code ( see " The UNIVAC SHORT CODE "), the first programming language actually used on a computer ( predated by Zuse ’ s conceptual Plankalkul ).

Acquiring then Eckert-Mauchly Computer Corporation and Engineering Research Associates along with Remington Rand, the company developed the successful UNIVAC computer series and signed a valuable cross-licensing deal with IBM.

The UNIVAC I ( UNIVersal Automatic Computer I ) was the first commercial computer produced in the United States.

As well as being the first American commercial computer, the UNIVAC I was the first American computer designed at the outset for business and administrative use ( i. e., for the fast execution of large numbers of relatively simple arithmetic and data transport operations, as opposed to the complex numerical calculations required by scientific computers ).
