The fourth generation computers began with the shipment of CPS-1, the first commercial microprocessor microcomputer in 1972 and for the purposes of this list marks the end of the "early" third generation computer era. Note that third generation computers were offered well into the 1990s. The list is organized by delivery year to customers or ...
The A-0 high-level compiler is invented by Grace Murray Hopper. April 1952: US IBM introduces the IBM 701, the first computer in its 700 and 7000 series of large scale machines with varied scientific and commercial architectures, but common electronics and peripherals. Some computers in this series remained in service until the 1980s. June 1952: US
Zuse, however, did not know of Shannon's work and developed the groundwork independently [11]: 149 for his first computer Z1, which he designed and built from 1935 to 1938. Zuse's coworker Helmut Schreyer built an electronic digital experimental model of a computer using 100 vacuum tubes [29] in 1942, but it was lost at the end of the war.
Third-generation computers were offered well into the 1990s; for example the IBM ES9000 9X2 announced April 1994 [30] used 5,960 ECL chips to make a 10-way processor. [31] Other third-generation computers offered in the 1990s included the DEC VAX 9000 (1989), built from ECL gate arrays and custom chips, [32] and the Cray T90 (1995).
Timeline of computing presents events in the history of computing organized by year and grouped into six topic areas: predictions and concepts, first use and inventions, hardware systems and processors, operating systems, programming languages, and new application areas.
