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.
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 ...
In the first generation, word-oriented computers typically had a single accumulator and an extension, referred to as, e.g., Upper and Lower Accumulator, Accumulator and Multiplier-Quotient (MQ) register. In the second generation, it became common for computers to have multiple addressable accumulators.
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 ...

A vacuum-tube computer, now termed a first-generation computer, is a computer that uses vacuum tubes for logic circuitry. While the history of mechanical aids to computation goes back centuries, if not millennia, the history of vacuum tube computers is confined to the middle of the 20th century. Lee De Forest invented the triode in 1906.
After the second world war he established the Computing Machine Laboratory at the University of Manchester where he created the project that built the world's first stored-program computer, the Manchester Baby. 1962 Nygaard, Kristen: With Ole-Johan Dahl, invented the proto-object oriented language SIMULA. 1642 Pascal, Blaise
