The first configuration interaction calculations were carried out in Cambridge on the EDSAC computer in the 1950s using Gaussian orbitals by Boys and coworkers.

Electronic Delay Storage Automatic Calculator ( EDSAC ) was an early British computer.

EDSAC was the second usefully operational electronic digital stored-program computer.

Later the project was supported by J. Lyons & Co. Ltd., a British firm, who were rewarded with the first commercially applied computer, LEO I, based on the EDSAC design.

They also learned from Goldstine that, back in the UK, Douglas Hartree and Maurice Wilkes were actually building another such machine, the pioneering EDSAC computer, at the University of Cambridge.

He started his computing career programming the pioneering EDSAC computer, designed and built at Cambridge University.

In 1952, OXO ( or Noughts and Crosses ) for the EDSAC computer became one of the first known video games.

It was developed on the EDSAC computer, which uses a cathode ray tube as a visual display to display memory contents.

* May 6 – EDSAC, the first practicable stored-program computer, runs its first program at Cambridge University.

On May 6, 1949 the EDSAC in Cambridge ran its first program, and due to this event, it is considered " the first complete and fully operational regular electronic digital stored-program computer ".

In the early 1960s Peter Swinnerton-Dyer used the EDSAC computer at the University of Cambridge Computer Laboratory to calculate the number of points modulo p ( denoted by N < sub > p </ sub >) for a large number of primes p on elliptic curves whose rank was known.

Wilkes received the Turing Award in 1967, with the following citation: " Professor Wilkes is best known as the builder and designer of the EDSAC, the first computer with an internally stored program.

The Computer Laboratory built and operated the world ’ s first fully operational practical stored program computer ( EDSAC, 1949 ) and offered the world ’ s first taught course in computer science in 1953.

In October 1946, work began under Maurice Wilkes on EDSAC ( Electronic Delay Storage Automatic Calculator ), which subsequently became the world ’ s first fully operational and practical stored program computer when it ran its first program on 6 May 1949.

It was replaced by EDSAC 2, the first microcoded and bitsliced computer, in 1958.

* EDSAC – world ’ s first practical stored program electronic computer ( 1949 – 1958 )

OXO was a computer game written for the EDSAC computer in 1952, an implementation of the game known as Noughts and Crosses in the UK, or tic-tac-toe in the United States.

OXO did not have widespread popularity because the EDSAC was a computer unique to Cambridge.

This lead to the development of a commercial version of EDSAC developed by Lyons, called LEO, the first computer used for commercial business applications.

* Leslie Treloar, rheologist and expert on rubber, and Maurice Wilkes, creator of the EDSAC computer and inventor of microprogramming, worked at TRE briefly during World War II.

EDSAC ran its first programs on 6 May 1949, when it calculated a table of squares and a list of prime numbers.

EDSAC was completed and ran its first program in May 1949.

Built in 1949, the EDSAC used a mercury delay line memory.

It was on the boat home that Wilkes planned the original design of EDSAC, which was to become operational in May 1949.

It was not a Turing complete computer, which distinguishes it from more general machines, like contemporary Konrad Zuse's Z3 ( 1941 ), or later machines like the 1946 ENIAC, 1949 EDVAC, the University of Manchester designs, or Alan Turing's post-War designs at NPL and elsewhere.

Auerbach discusses his work at Burroughs 1949 – 1957 managing development for the SAGE project, BEAM I computer, the Intercontinental Ballistic Missile System, a magnetic core encryption communications system, and Atlas missile.

It was the outline of a stored-program computer that would eventually be completed in August 1949.

Alan Turing searched for them on the Manchester Mark 1 in 1949, but the first successful identification of a Mersenne prime, M < sub > 521 </ sub >, by this means was achieved at 10: 00 P. M. on January 30, 1952 using the U. S. National Bureau of Standards Western Automatic Computer ( SWAC ) at the Institute for Numerical Analysis at the University of California, Los Angeles, under the direction of Lehmer, with a computer search program written and run by Prof. R. M.

* 1949 – Ward Cunningham, American computer programmer, developed the first wiki

* 1949 – Bill Buxton, Canadian computer scientist and designer

In 1949 – 1950, Charley Adama created a " Bouncing Ball " program for MIT's Whirlwind computer.

Howard G. " Ward " Cunningham ( born May 26, 1949 ) is an American computer programmer who developed the first wiki.

BINAC, the Binary Automatic Computer, was an early electronic computer designed for Northrop Aircraft Company by the Eckert-Mauchly Computer Corporation in 1949.

Using computer equipment coupled with an electronic incarnation of the player piano, they created re-performances of Tatum ’ s first four commercial tracks, from March 21, 1933, and the nine tracks from the April 2, 1949 live concert at Los Angeles ' Shrine Auditorium.

Anita Borg ( January 17, 1949 – April 6, 2003 ) was an American computer scientist.

Index registers, commonly known as a B-line in early British computers, were first used in the British Manchester Mark 1 computer, in 1949.

Around 1949, Leontief used the primitive computer systems available at the time at Harvard to model data provided by the U. S. Bureau of Labor Statistics to divide the U. S. economy into 500 sectors.

However, his laboratory's computer was the first practical stored program computer to be completed, and operated successfully from May 1949.

Dr Charles L. Forgy ( born December 12, 1949 in Texas ) is a computer scientist, known for developing the Rete algorithm used in his OPS5 and other production system languages used to build expert systems.

* John Markoff ( born 1949 ), American journalist of computer industry and technology

Established in 1949, it is housed in the heart of the campus and is served by studios, workshops, computer lab and library.

When Cuthbert Hurd became the next PhD to be hired by IBM in 1949, he was offered a position with Eckert, but instead founded the Applied Science Department, and later directed the development of IBM's first commercial stored program computer ( the IBM 701 ) based on the demand demonstrated by applications such as those of Eckert.
