Apart from the computers discussed above, some other notable devices of the first generation were EDSAC by Maurice Wilkes (1949), BINAC by Eckert's and Mauchly's Electronic Control Company (1949). Whirlwind I by J. Forrester (1949), SEAC by Samuel Alexander and Ralph Slutz (1950), SWAC by Harry Huskey (1950), UNIVAC by Eckert-Mauchly Corporation (1951), IAS computer by Institute of Advanced Study (1952) and IBM 701, 1952.
The first generation computers were run by several types of memories and the gradual advancement in the technology applied for development of memories deserves mention. Mercury filled tubes called "Delay Lines" were used for high speed internal memory in computers like EDSAC, BINAC, SEAC, DEUCE and pilot model of ACE. In Manchester baby it was the electronic memory where a two-dimensional rectangular array of binary digits was stored on the face of a cathode ray tube.
This technique was also employed in SWAC, IAS computers and IBM 701. In drum memory, data was stored magnetically on the surface of a metal cylinder. The final discovery in the history of first generation computer was the development of magnetic core memory by Jay Forrester. The ferrite core memory, as it was called, was tested in a computer in 1953 and the device was put to use in 1954 for the first simulations of the neural network.
