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.
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.
First stored-program computer to be sold, but did not work for customer. CSIRAC: 1949 1: Oldest surviving complete first-generation electronic computer — unrestored and non-functional. SEAC: 1950 1 First U.S. stored-program computer to become operational. Built by and for the U.S. National Bureau of Standards. Used solid-state diode circuits ...
An early portable computer with integrated monitor; the 5100 was possibly one of the first portable microcomputers using a CRT display. Sphere 1: 1975: A personal computer that was among the earliest complete all-in-one microcomputers that could be plugged in, turned on, and be fully functional. Tandberg Radiofrabrikk/Tandberg Data TDV-2114 ...
The first computer to use magnetic tape. EDVAC could have new programs loaded from the tape. Proposed by John von Neumann, it was installed at the Institute for Advance Study, Princeton University, Princeton, New Jersey, US. 1951: Australia CSIRAC used to play music – the first time a computer was used as a musical instrument. 1951: US
The original IBM Personal Computer, with monitor and keyboard. The IBM Personal Computer, commonly known as the IBM PC, spanned multiple models in its first generation (including the PCjr, the Portable PC, the XT, the AT, the Convertible, and the /370 systems, among others), from 1981 to 1987.
First known system with 4 line "caption" [48] and software scaling and rotation Commodore PET 2001: 1977 — 1000 Bytes: 40×25 Mono 9" Mono monitor "Full": Limited 320x200 Mono Semi: 80×50 using part of its pseudo graphic characters set (80x50, 40x200) BG, SG — Original computer with non ASCII character set. Exidy Sorcerer: 1978: 1920 Bytes ...
The cassette tape was a common low-cost and low-performance mass storage device for a generation of home computers. Home computers were a class of microcomputer that existed from 1977 to about 1995. During this time it made economic sense for manufacturers to make microcomputers aimed at the home user.
