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 team created a functional transistor to switch electronic signals using cellulose-based electrolyte and lignin-derived organic semiconductors. This breakthrough could lead to further research in creating environmentally friendly electronic devices and exploring the possibility of integrating electronics into living plants for monitoring and ...
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.
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.
Its first fully electronic turntables. The first industrially manufactured car radio, the "Philco Transitone" from the "Storage Battery Co." in Philadelphia, USA, comes on the market. The first shortwave radio – Rundfunkübertragung overseas broadcast by the station PCJJ the Philips factories in Eindhoven in the Dutch colonies.
Whirlwind, the first real-time computer was built at MIT by the team of Jay Forrester for the US Air Defense System, became operational. This computer is the first to allow interactive computing, allowing users to interact with it using a keyboard and a cathode-ray tube.
A second application was a transistorized digital computer to be used in a Navy track-while-scan shipboard radar system. Several models were completed: TRADIC Phase One computer, Flyable TRADIC, Leprechaun (using germanium alloy junction transistors in 1956) and XMH-3 TRADIC. TRADIC Phase One was developed to explore the feasibility, in the ...
