The TR-63 was also the first transistor radio to use all miniature components. (The term "pocket" was a matter of some interpretation, as Sony allegedly had special shirts made with oversized pockets for their salesmen.) 1955 Chrysler–Philco all transistor car radio – "Breaking News" radio broadcast announcement
The world's first transistorised computer was the Manchester Transistor Computer, operational in 1953. [3] The 1955 Harwell CADET is a contender for the title of first fully transistorised computer. Many of the early transistorised computers used valves for non-computing elements such as the power supply and clock.
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 ...
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 Regency TR-1, which used Texas Instruments' NPN transistors, was the world's first commercially produced transistor radio in 1954. Size: 3×5×1.25 inch (7.6×12.7×3.2 cm) Following development of transistor technology, bipolar junction transistors led to the development of the transistor radio.
An early 2000s transistor radio (Sony Walkman SRF-S84 transistor radio, released 2001, shown without earphones) Rock 'n roll music became popular at the same time as transistor radios. Parents found that purchasing a small transistor radio was a way for children to listen to their music without using the family tube radio.
The 48-bit machine they completed in November 1953 was the world's first transistor computer, with 550 diodes and 92 transistors, and was manufactured by STC. An improved version completed in April 1955 had 1,300 diodes and 200 transistors, and was sold by Metropolitan-Vickers as the Metrovick 950. [10]
The transmitter Witzleben uses the new standard with 441 lines and 25 image changes, i.e. 50 fields of 220 half-lines. Until the HDTV era the interlace method remains in use. First movie encoder make it possible not to send the TV live, but to rely on recordings. 1938 The improved AEG tape-recorder "Magnetophon K4" is first used in radio studios.
