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.
In the late 1960s Busicom sought contracts with U.S. semiconductor companies, which were then the leaders in semiconductor development, to produce advanced integrated circuits for its calculators and other business machines. Two contracts in particular were of great technological importance.

In the very beginning, of course, was the abacus, a sort of hand-operated mechanical calculator using beads on rods, first used by Sumerians and Egyptians around 2000 BC. The principle was simple, a frame holding a series of rods, with ten sliding beads on each. When all the beads had been slid across the first rod, it was time to move one across o...
The story of the electronic calculator really begins in the late 1930s as the world began to prepare for renewed war. To calculate the trigonometry required to drop bombs 'into a pickle barrel' from 30,000 feet, to hit a 30-knot Japanese warship with a torpedo or to bring down a diving Stuka with an anti-aircraft gun required constantly updated aut...
It had taken 3,700 years to move from the abacus to the first mechanical calculators and a further 250 years for mechanics to give way to electronics. Yet it would take barely a decade for the calculator to make its third metamorphosis, from a heavy, bulky, expensive desktop machine that needed AC mains power to a cheap and compact battery or solar...
By 1980, pocket and desktop calculators had essentially reached the forms we recognise today; compact in form, using single chips and LCD displays, operated via silicone membrane or dome switch keyboards, powered by solar cells or button batteries and capable of a wide range of functions. Pocket calculators had also become very cheap, with some sel...
Sep 25, 2024 · The first was with Mostek for the development of advanced LSI (Large-Scale Integration) technology for Busicom’s basic calculators that were manufactured in its Osaka factory. The second contract was with a small start-up company, founded in 1968, called Intel Corporation.
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.
A Brief History: The Busicom LE-120A, known as the HANDY, is the first handheld calculator to use a “calculator on a chip” integrated circuit. According to the Vintage Calculators Web Museum, the calculator featured a 12-digit display in red LED and cost $395 when it first went on sale in January 1971.
The history of the calculator, or what we know of it, began with the hand-operated Abacus in Ancient Sumeria and Egypt in around 2000-2500 BC. These are very simple devices compared to...
