The first chips that could be considered microprocessors were designed and manufactured in the late 1960s and early 1970s, including the MP944 used in the Grumman F-14 CADC. [1] Intel's 4004 of 1971 is widely regarded as the first commercial microprocessor. [2]
In 1970 and 1971, Weisbecker developed a new 8 bit architecture computer system. This work preceded the release of the 4004 by competitor Intel.He built a demonstration home computer powered by the 1802 called FRED (Flexible Recreational and Educational Device) that utilized cassette tape for storage and a television for display.

The earliest multi-chip microprocessors were the Four-Phase Systems AL1 in 1969 and Garrett AiResearch MP944 in 1970, each using several MOS LSI chips. [33] On November 15, 1971, Intel released the world's first single-chip microprocessor, the 4004, on a single MOS LSI chip.
The most famous member of the 650x series was the 6502, developed in 1975, which was priced at 15% of the cost of an Intel 8080, and was subsequently used in many commercial products, including the Apple II, PET, VIC-20, Atari 8-bit computers, arcade video games, Oric computers, and the BBC Micro.
Using a locally produced microprocessor based on the design of the Intel 4004. First built in 1972, a small number shipped in early 1973. [22] [23] Micral N: Intel 8008 [24] 1973: Awarded the title of "the first personal computer using a microprocessor" by a panel at the Computer History Museum in 1986. [25] Seiko 7000 Intel 8080: 1974
Gary Arlen Kildall (/ ˈ k ɪ l d ˌ ɔː l /; May 19, 1942 – July 11, 1994) was an American computer scientist and microcomputer entrepreneur. During the 1970s, Kildall created the CP/M operating system among other operating systems and programming tools, [5] and subsequently founded Digital Research, Inc. to market and sell his software products.
In 1969, he worked with Intel's Ted Hoff and Stanley Mazor to reduce the three-chip Busicom proposal into a one-chip architecture. In 1970, that architecture was transformed into a silicon chip, the Intel 4004, by Federico Faggin, with Shima's assistance in logic design. [3] [4] [5] He later joined Intel in 1972.
Gerald Anderson Lawson (December 1, 1940 – April 9, 2011) was an American electronic engineer.Besides being one of the first African-American computer engineers in Silicon Valley, Lawson was also known for his work in designing the Fairchild Channel F video game console, leading the team that refined ROM cartridges for durable use as commercial video game cartridges.
