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.
Similarly, indirect addressing became more common in the second generation, either in conjunction with index registers or instead of them. While first-generation computers typically had a small number of index registers or none, several lines of second-generation computers had large numbers of index registers, e.g., Atlas, Bendix G-20, IBM 7070.
Flyable TRADIC was used to establish the feasibility of using an airborne solid-state computer as the control element of a bombing and navigation system. Leprechaun [6] [7] [8] was a second-generation laboratory research transistor digital computer designed to explore direct-coupled transistor logic (DCTL). The TRADIC Phase One computer was ...
Computers introduced between 1959 and 1964, often regarded as second-generation computers, were based on discrete transistors and printed circuits – resulting in smaller, more powerful and more reliable computers. 1959 UK
Typically, second-generation computers were composed of large numbers of printed circuit boards such as the IBM Standard Modular System, [143] each carrying one to four logic gates or flip-flops. At the University of Manchester, a team under the leadership of Tom Kilburn designed and built a machine using the newly developed transistors instead ...
After three years of development, RCA introduced by 1959 [1] the all-transistor RCA 501, a medium- to large-scale computer which – according to the sales brochures – was "the world's most advanced electronic data processing system". [2]
