Limit production cost
- In order to limit production cost, Busicom wanted to design a calculator engine that would be based on a few integrated circuits (ICs), containing some ROMs and shift registers and that could be adapted to a broad range of calculators by just changing the ROM IC chips.

History
The Nippon Calculating Machine Corp was incorporated in 1945 and changed its name in 1967 to Business Computer Corporation, Busicom. Due to a recession in Japan in 1974, Busicom became the first major Japanese company in the calculator industry to fail. Originally, they made Odhner type mechanical calculators and then moved on to electronic calculators always using state of the art designs. They made the first calculator with a microprocessor for their top of the line machinesand they were th...

In order to limit production cost, Busicom wanted to design a calculator engine that would be based on a few integrated circuits (ICs), containing some ROMs and shift registers and that could be adapted to a broad range of calculators by just changing the ROM IC chips. Busicom's engineers came up with a design that required 12 ICs. In April 1968, engineer Masatoshi Shima was tasked with designing a special-purpose LSI chipset, along with his supervisor Tadashi Tanba, for use in the Busicom 14...
Broughtons of Bristol is a company selling and maintaining a broad line of business machines. They used to buy most of their equipment from Busicom and bought their trade name when they went bankrupt in 1974.

Nov 15, 2023 · The 4004 was primarily used in calculators, the first being the Busicom 141-PF. In fact, it was Busicom that actually developed the design of what would become the Intel 4004. Busicom approached Intel to help them finalize the design and manufacture their “calculator engine”.
Sep 25, 2024 · One of the most technologically adventurous calculator manufacturers in the late 1960s and early 1970s was the small Japanese company Busicom Corporation. Under its previous name of Nippon Calculating Machine Corporation (NCM) it produced mechanical pinwheel calculators in the mid-1960s.
Work on the 4004 began in 1969, when Japanese electronics company Busicom asked Intel to design a chipset for its upcoming desktop calculator, the 141-PF. That calculator was where the microprocessor found its first application, but it would ultimately turn up in millions of devices.
