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
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 ...
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.
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.
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 world's first mass-produced computer IBM 704: 1954 123: The first mass-produced computer with floating-point arithmetic hardware for scientific use IBM 705: 1954 Mostly compatible with the IBM 702, for business use. There is one that is not in operating condition at Computermuseum München. BESK: 1954 1 Sweden's first computer and was the ...
1954: Regency introduced a pocket transistor radio, the TR-1, powered by a "standard 22.5V Battery". 1960: Sony introduced their first transistorized radio, small enough to fit in a vest pocket, and able to be powered by a small battery. It was durable, because there were no tubes to burn out.
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.
