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.
IBM 604 Electronic Calculator at NEMO national science museum in Amsterdam. Note plugboard control panel used to program the 604, at bottom.. The IBM 604 Electronic Calculating Punch was the world's first mass-produced electronic calculator along with its predecessor the IBM 603. [1]
ENIAC (/ ˈ ɛ n i æ k /; Electronic Numerical Integrator and Computer) [1] [2] was the first programmable, electronic, general-purpose digital computer, completed in 1945. [ 3 ] [ 4 ] Other computers had some of these features, but ENIAC was the first to have them all.
The first all-electronic prototype was demonstrated to the board of the company in December 1958. [4] This prototype was later donated by the company to the Science Museum in London, where Kitz had originally had the idea for the electronic calculator. It has been on display surrounded by the mechanical calculators that it was to make obsolete.
The Victor 3900 is the first electronic calculator to have been built entirely of integrated circuits (ICs). [1] [2] For its era, the 3900 is extremely advanced; it has a 4-inch (100 mm) cathode ray tube screen to produce a 5-line display, has separate memory for storing three intermediate results, supports numerical rounding, and is still "smaller than a typewriter".
Was the first scientific calculator to fly in space in 1973. [5] HP-35 calculators were carried on the Skylab 3 and Skylab 4 flights, between July 1973 and February 1974. [6] Is the first pocket calculator with a numeric range that covered 200 decades (more precise 199, ±10 ±99). [5]
Most of the calculators at that time worked using gears and could be operated by hand using a crank or using a motor (see adding machine). The model 14-A, the first electronic calculator produced by Casio. Toshio possessed some knowledge of electronics and set out to make a calculator using solenoids. After dozens of prototypes were tested, the ...
The Sharp EL-8, also known as the ELSI-8, [1] was one of the earliest mass-produced hand-held electronic calculators [1] and the first hand-held calculator to be made by Sharp. Introduced around the start of 1971, [ note 1 ] it was based on Sharp's preceding QT-8D and QT-8B compact desktop calculators and used the same logic circuits, but it ...
