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).
The microprocessor led to the microcomputer revolution, with the development of the microcomputer, which would later be called the personal computer (PC). Most early microprocessors, such as the Intel 8008 and Intel 8080, were 8-bit. Texas Instruments released the first fully 16-bit microprocessor, the TMS9900 processor, in June 1976. [71]

The TI-99/4 and TI-99/4A are home computers released by Texas Instruments in 1979 and 1981, respectively. [2] Based on Texas Instruments's own TMS9900 microprocessor originally used in minicomputers, the TI-99/4 was the first 16-bit home computer. [3]
Date Location Event January United Kingdom (UK) Sinclair ZX80 was released for under £100.: 22 May Japan: The game Pac-Man was released. [1]June United States (US) Commodore released the VIC-20, which had 3.5 KB of usable memory and was based on the MOS Technology 6502 processor.
SEAC (Standards Eastern Automatic Computer) demonstrated at US NBS in Washington, DC – was the first fully functional stored-program computer in the U.S. May 1950: UK The Pilot ACE computer, with 800 vacuum tubes, and mercury delay lines for its main memory, became operational on 10 May 1950 at the National Physical Laboratory near London.
While the earliest microprocessor ICs literally contained only the processor, i.e. the central processing unit, of a computer, their progressive development naturally led to chips containing most or all of the internal electronic parts of a computer. The integrated circuit in the image on the right, for example, an Intel 8742, is an 8-bit ...
In 1984, the U.S. Census Bureau began collecting data on computer and Internet use in the United States; their first survey showed that 8.2% of all U.S. households owned a personal computer in 1984, and that households with children under the age of 18 were nearly twice as likely to own one at 15.3% (middle and upper middle class households ...
