An electronic calculator is typically a portable electronic device used to perform calculations, ranging from basic arithmetic to complex mathematics.. The first solid-state electronic calculator was created in the early 1960s. Pocket-sized devices became available in the 1970s, especially after the Intel 4004, the first microprocessor, was developed by Intel for the Japanese calculator ...


The first step was seen in 1961 with the arrival of ANITA (A New Inspiration To Arithmetic/Accounting). This was the world's first all-electronic desktop calculator and it was developed in Britain by Control Systems Ltd., marketed under its Bell Punch and Sumlock brands.


Research into downsizing calculators by replacing transistors with ICs (integrated circuits) resulted in creation of the world's first electronic calculator incorporating ICs (CS-31A). The weight, number of parts and price of the new product were almost half those of the first calculator Sharp put on the market.


The “calculator-on-a-chip” is a metal oxide semiconductor (MOS) integrated circuit announced by Texas Instruments in September of 1971. A variation was sold in the early handheld electronic calculators of companies like Bowmar, as well as in TI's first portable calculator, the Datamath, introduced in September, 1972.


The first all-electronic desktop calculator was the British Bell Punch/Sumlock Comptometer ANITA, which used vacuum tubes, cold-cathode tubes, and Dekatrons in its circuits. ANITA weighed 33 pounds but was quiet and quick, which made her an instant success. In 1963, Friden EC-130 overtook ANITA with an all-transistor design, able to stack 13 ...


It used a CRT (cathode ray tube ) television tube - type of display and was also one of the first fully electronic calculators in the world. 1964 -- In March, Japan's Sony Corporation claims to perfect the world's first all-transistorized (no vacuum tube) desk-top electronic calculator.


Electronic CalculatorsThe Electronic Age elbowed out the Mechanical Age in the 1960s. Calculator manufacturers had to adapt or perish. Electronics firms not previously in the calculator business saw this transition as a chance to compete on a newly level field. Competition fueled innovation. By the late 1960s, desktop electronic calculators were lighter and quieter than their mechanical ancestors.


It was not until 1948 that a pocket-sized calculator was invented and came in the form of the Curta calculator. It was not until the 1960s and the advent of electronic devices that the electronic calculator came to be. ANITA (A New Inspiration To Arithmetic/Accounting) was the first all-electric desktop calculator and was released in 1961.


The first electronic desktop calculators. They use vacuum tubes. The world's first electronic desktop calculators were announced by the Bell Punch Co., Uxbridge, England - the Anita Mk VII for the continental European market and the Anita Mk 8 for other markets. These models used cold-cathode vacuum tubes and numerical display ("Nixie" type) tubes.


William Seward Burroughs invented the first practical calculator. Read more about the history of calculators. ... Electronic Calculators . William Seward Burroughs (1857 – 1898): In 1885, Burroughs filed his first patent for a calculating machine. However, his 1892 patent was for an improved calculating machine with an added printer.
