If the TRADIC can be called fully transistorized while incorporating vacuum tubes, then the Manchester University Transistor Computer should also be, in which case that is the first transistorized computer and not the TRADIC. If neither can be called fully transistorized, then the CADET was the first fully transistorized computer in February 1955.
NCR 304 computer system Camp Pendleton, California. The NCR 304 computer, announced in 1957, [1] first delivered in 1959, [2] [3] was National Cash Register (NCR)'s first transistor-based computer. The 304 was developed and manufactured in cooperation with General Electric, [4] where it was also used internally. [5]
TRADIC. This is a list of transistorized computers, which were digital computers that used discrete transistors as their primary logic elements. Discrete transistors were a feature of logic design for computers from about 1960, when reliable transistors became economically available, until monolithic integrated circuits displaced them in the 1970s.
IEEE Global History Network, The Transistor and Portable Electronics. All about the history of transistors and integrated circuits. Transistorized. Historical and technical information from the Public Broadcasting Service; This Month in Physics History: November 17 to December 23, 1947: Invention of the First Transistor.
A transistor computer, now often called a second-generation computer, [1] is a computer which uses discrete transistors instead of vacuum tubes. The first generation of electronic computers used vacuum tubes, which generated large amounts of heat, were bulky and unreliable.
Harwell CADET Computer. The Harwell CADET was the first fully transistorised computer in Europe, and may have been the first fully transistorised computer in the world.. The electronics division of the Atomic Energy Research Establishment at Harwell, UK built the Harwell Dekatron Computer in 1951, [1] which was an automatic calculator where the decimal arithmetic and memory were electronic ...
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.
The development of transistor technology, followed by the invention of integrated circuit chips, led to revolutionary breakthroughs. Transistor-based computers and, later, integrated circuit-based computers enabled digital systems to gradually replace analog systems, increasing both efficiency and processing power.
