In 1946, the researchers resigned from the University of Pennsylvania and formed the Eckert–Mauchly Computer Corporation. ENIAC was a large, modular computer, composed of individual panels to perform different functions. Twenty of these modules were accumulators that could not only add and subtract, but hold a ten-digit decimal number in memory.
The U.S. Army introduced ENIAC, the Electronic Numerical Integrator And Computer, to the public in a press conference at the University of Pennsylvania in Philadelphia. The world's first electronic computer weighed 30 tons, had 18,000 vacuum tubes , and was 8 feet (2.4 m) tall, 3 feet (0.91 m) deep, and 100 feet (30 m) long.
The Manchester Mark 1 was dismantled and scrapped in August 1950, [28] replaced a few months later by the first Ferranti Mark 1, the world's first commercially available general-purpose computer. [1] Between 1946 and 1949, the average size of the design team working on the Mark 1 and its predecessor, the Baby, had been about four people.
ENIAC (Electronic Numerical Integrator and Computer): One of the first totally electronic, vacuum tube, digital, program-controlled computers was unveiled although it was shut down on 9 November 1946 for a refurbishment and a memory upgrade, and was transferred to Aberdeen Proving Ground, Maryland in 1947.
The Manchester Baby was designed as a test-bed for the Williams tube, an early form of computer memory, rather than as a practical computer.Work on the machine began in 1947, and on 21 June 1948 the computer successfully ran its first program, consisting of 17 instructions written to find the highest proper factor of 2 18 (262,144) by trying every integer from 2 18 − 1 downwards.
SEAC (Standards Eastern Automatic Computer) demonstrated at US NBS in Washington, DC – was the first fully functional stored-program computer in the U.S. May 1950: UK The Pilot ACE computer, with 800 vacuum tubes, and mercury delay lines for its main memory, became operational on 10 May 1950 at the National Physical Laboratory near London.
EDVAC (Electronic Discrete Variable Automatic Computer) was one of the earliest electronic computers. It was built by Moore School of Electrical Engineering at the University of Pennsylvania . [ 1 ] [ 2 ] : 626–628 Along with ORDVAC , it was a successor to the ENIAC .
