A general-purpose computer is made up of three basic functional blocks. The central processing unit (CPU), which combines arithmetic and control logic functions; a storage unit for storing programs and data; and I/O units (UART, DMA controller, timer/counters, device controllers, etc.) that interface to external devices such as monitors, printers, ...
A major step in meeting the Westinghouse engineers’ goal of putting a CPU on a single chip took place as IC manufacturing processes transitioned from bipolar to metal oxide Semiconductor (MOS) technology. By the mid-1960s, MOS enabled large scale integration (LSI) chips that could accommodate hundredsof logic gates. Designers of consumer digital pr...
Fairchild Semiconductor began the development of standardized MOS computer system building blocks in 1966. The 3804, its first complete CPU processor bit slice, featured instruction decoding, a parallel four-bit ALU, registers, full condition code generation, and the first use of an I/O bus. Designer Lee Boysel noted that it would not be considered...
Intel’s first effort in this product category, the MCS-4 Micro Computer Set, was conceived as the most efficient way of producing a set of calculator chips. Created in January 1971 by a team of logic architects and silicon engineers—Federico Faggin, Marcian (Ted) Hoff, Stanley Mazor, and Masatoshi Shima—for Japanese calculator manufacturer Busicom,...
Presented with this convoluted history, how should historians assign credit for the invention of the microprocessor? Ultimately it depends on the definition of the word as expressed by different experts in the field. According to technology analyst Nick Treddenick, “I have looked at [Boysel’s] AL1 design from the papers written about it through the...
Most historians who follow the tangled threads underlying the origins of the microprocessor conclude that it was simply an idea whose time had come. Throughout the decade of the 1960s, numerous semiconductor manufacturers contributed to an ever-increasing number of transistors that could be integrated onto a single silicon chip. Correspondingly man...

In 1969, Nippon Calculating Machine Corporation approached Intel to design 12 custom chips for its new Busicom 141-PF* printing calculator.
The first commercial product to use a microprocessor was the Busicom calculator 141-PF. The 4004 was also used in the first microprocessor-controlled pinball game, a prototype produced by Dave Nutting Associates for Bally in 1974.

Nov 15, 2021 · This chip, originally created to power a calculator from a Japanese company called Busicom, was the first really general-purpose computing chip.
Marcian “Ted” Hoff (PhD '62 EE), is best known as the architect of the first microprocessor. Intel’s 4004 was released in November 1971, 35 years ago this month. The history that his ingenuity helped spawn is now the subject of a new DVD, the Microprocessor Chronicles.
