A vacuum-tube computer, now termed a first-generation computer, is a computer that uses vacuum tubes for logic circuitry. While the history of mechanical aids to computation goes back centuries, if not millennia, the history of vacuum tube computers is confined to the middle of the 20th century. Lee De Forest invented the triode in 1906.
A follow-up to the UNIVAC 1103 scientific computer AN/FSQ-7: 1958 Largest vacuum tube computer ever built. 52 were built for Project SAGE. ZEBRA: 1958 55: Designed in Holland and built by Britain's Standard Telephones and Cables [24] Ferranti Perseus: 1959 2 [25] [26] [27] Rice Institute Computer: 1959 1: Operational 1959-1971, 54-bit tagged ...
A vacuum tube, electron tube, [1] [2] ... (such as the television picture tube, ... The 1946 ENIAC computer used 17,468 vacuum tubes and consumed 150 kW of power.
Valves (vacuum tubes) seen on end in a recreation of the Colossus computer. Colossus was developed for the "Newmanry", [31] the section headed by the mathematician Max Newman that was responsible for machine methods against the twelve-rotor Lorenz SZ40/42 on-line teleprinter cipher machine (code-named Tunny, for tunafish).
7AK7 vacuum tubes in a 1956 UNIVAC I computer. UNIVAC I used 6,103 vacuum tubes, [24] [25] weighed 16,686 pounds (8.3 short tons; 7.6 t), consumed 125 kW, [26] and could perform about 1,905 operations per second running on a 2.25 MHz clock. The Central Complex alone (i.e. the processor and memory unit) was 4.3 m by 2.4 m by 2.6 m high.
Whirlwind I was a Cold War-era vacuum-tube computer developed by the MIT Servomechanisms Laboratory for the U.S. Navy.Operational in 1951, it was among the first digital electronic computers that operated in real-time for output, and the first that was not simply an electronic replacement of older mechanical systems.
A January 15, 1941, story in the Des Moines Register announced the ABC as "an electrical computing machine" with more than 300 vacuum tubes that would "compute complicated algebraic equations" (but gave no precise technical description of the computer). The system weighed more than seven hundred pounds (320 kg).
The Gamma 3 was an early electronic vacuum-tube computer.It was designed by Compagnie des Machines Bull in Paris, France and released in 1952.. Originally designed as an electronic accelerator for electromechanical tabulating machines, similar to the IBM 604, it was gradually enhanced with new features and evolved into a first-generation stored program computer (Gamma AET, 1955, then ET, 1957).
