Fairchild SemiconductorFairchild Semiconductor International, Inc. was an American semiconductor company based in San Jose, California. It was founded in 1957 as a division of Fairchild Camera and Instrument by the "traitorous eight" who defected from Shockley Semiconductor Laboratory. It became a pioneer in the manufacturing of transistors and of integrated circuits.Four-Phase Systems AL1The AL1 was an early 8-bit microprocessor slice designed by Four-Phase Systems and unveiled in February 1970. The chip was first used as part of Four-Phase's System IV/70 24-bit minicomputer to be used with terminals shipped in January 1971. It has been widely reported as one of the first microprocessor central processing units (CPU) publicly disseminated, pre-dating the Intel 4004 by one year. In modern terms, the AL1 is a bit-slice design.
IntelAmerican multinational technology companyIntel Corporation is an American multinational technology company headquartered in Santa Clara, California. It designs, manufactures, and sells computer components such as central processing units (CPUs) and related products for business and consumer markets.
Lee BoyselLee Loren Boysel (December 31, 1938 – April 25, 2021) was an American electrical engineer and entrepreneur. While at Fairchild Semiconductor, he developed four-phase logic and built the first integrated circuit with over 100 logic gates, and designed the Fairchild 3800 / 3804 8-bit ALUs. Boysel designed the Four-Phase Systems AL1. He founded Four-Phase Systems to commercialize the technology, and sold the company to Motorola in 1981.
24-bit computingIn computer architecture, 24-bitintegers, memory addresses, or other data units are those that are 24 bits (3 octets) wide. Also, 24-bit central processing unit (CPU) and arithmetic logic unit (ALU) architectures are those that are based on registers, address buses, or data buses of that size.
Wafer fabricationWafer fabrication is a procedure composed of many repeated sequential processes to produce complete electrical or photoniccircuits on semiconductorwafers in a semiconductor device fabrication process. Examples include production of radio frequency (RF) amplifiers, LEDs, optical computer components, and microprocessors for computers. Wafer fabrication is used to build components with the necessary electrical structures.
Robert NoyceRobert Norton Noyce (December 12, 1927 – June 3, 1990), nicknamed "the Mayor of Silicon Valley", was an American physicist and entrepreneur who co-founded Fairchild Semiconductor in 1957 and Intel Corporation in 1968. He was also credited with the realization of the first monolithic integrated circuit or microchip made with silicon, which fueled the personal computer revolution and gave Silicon Valley its name.
MotorolaMotorola, Inc. () was an American multinational telecommunications company based in Schaumburg, Illinois. It was founded by brothers Paul and Joseph Galvin in 1928 as Galvin Manufacturing Corporation and was renamed Motorola in 1947. Many of Motorola's products had been radio-related communication equipment such as two-way radios, consumer walkie-talkies, cellular infrastructure, mobile phones, satellite communicators, pagers, as well as cable modems and semiconductors.
Joint Computer ConferenceThe Joint Computer Conferences were a series of computer conferences in the United States held under various names between 1951 and 1987. The conferences were the venue for presentations and papers representing "cumulative work in the [computer] field." Originally a semi-annual pair, the Western Joint Computer Conference (WJCC) was held annually in the western United States, and a counterpart, the Eastern Joint Computer Conference (EJCC), was held annually in the eastern US.
Apple Infinite Loop campusThe Apple InfiniteLoopcampus (also known as AppleCampus 1 and by its address, 1 Infinite Loop) is an office complex owned and occupied by Apple Inc. in Cupertino, California. When it opened in 1993, the campus was used exclusively for the company's research and development activities. After returning to Apple in 1997, Steve Jobs made the campus the company's corporate headquarters.
