The 180-mil-square [0.18 inches-square (4.6 mm-square)] chip contains the logic for a four function 12-digit calculator - more than 2,100 transistors in 360 gates plus 160 flip-flops. Its promise of lower labor costs means a giant step toward a calculator for the consumer market. ... ...
4003, 10-bit shift register. 4004, 4-bit central processing unit (CPU) (the microprocessor) with a maximum clock speed of 750 kHz. Complete 4004 chip-sets were sent to Busicom early in 1971 and by March Shima had built a working 141-PF calculator.

In 1969, a Japanese calculator manufacturer called Busicom hired Intel to create chips for a calculator that Busicom designed. Intel devised a chipset (called the MCS-4---short for "Micro Computer System") composed of four integrated circuits (ICs) that dramatically simplified the calculator's internal design. In delivering its solution, Intel deve...
Some controversy existsover which chip was actually the first microprocessor, so historians generally add qualifying statements such as "single chip" and "commercial" to place a narrow focus on each company's achievement. At the time of the Intel 4004's commercial debut in mid-1971, a multi-chip microprocessor was already flying in the US Navy's F-...
Microprocessor technology has dramatically changed since 1971, when Intel's 4004 CPU ran at a mere 740 KHz and contained only 2,250 transistors using a 10 micrometer process. To show just how dramatically things have changed, we've compared the 4004 with Intel's latest top-of-the-line desktop CPU, the recently-announced Intel Core i9-12900K. Here's...
Due to its limited capabilities---and quickly getting eclipsed by more powerful chips such as the Intel 8008---the 4004 didn't see widespread use relative to the 8-bit Intel chips that followed. Still, here's a list of some products that incorporated a 4004 CPU. I've pulled many of these examples from a piece about the 4004I wrote for Technologizer...
Only five months after Intel announced the 4004 in Electronic News, the firm shipped the Intel 8008, the first 8-bit microprocessor. The 8008 launched an era of at-home hobby computers like the Mark-8, whose appearance on the cover of Radio-Electronics in 1974 spurred the personal computer industry. After the 8008, Intel followed up with the 8-bit ...
Jan 29, 2018 · In April 1969, Japanese company Busicom hired them to do LSI (Large-Scale Integration) work for a family of calculators. Busicom’s design, consisting of twelve interlinked chips, was...
Busicom was a Japanese calculator company. It owned the rights to the first commercial microprocessor, the Intel 4004, which began as the "Busicom Project" in 1968, before being developed as a single-chip microprocessor in partnership with Intel from 1969 to 1970. Busicom asked Intel to design a...
Nov 15, 2021 · And it all started with a calculator. In 1969, Japanese manufacturer Nippon Calculating Machine Corp. approached Intel to design a set of integrated circuits for its engineering prototype calculator, the Busicom 141-PF.

After many Zoom debugging session with Kintli, Scheffler got his transistor 4004 running the complete Busicom calculator app at 250kHz, only 3x slower than the original 750kHz chip. At first you might think “how slow,” but IMHO this is really a respectable result.
