Pocket calculators

"Pocket calculator" redirects here. For the song, see Computer World. By 1970, a calculator could be made using just a few chips of low power consumption, allowing portable models powered from rechargeable batteries. The first portable calculators appeared in Japan in 1970, and were soon marketed around the world. These included the Sanyo ICC-0081 "Mini Calculator", the Canon Pocketronic, and the Sharp QT-8B "micro Compet". The Canon Pocketronic was a development of the "Cal-Tech" project which had been started at Texas Instruments in 1965 as a research project to produce a portable calculator. The Pocketronic has no traditional display; numerical output is on thermal paper tape. As a result of the "Cal-Tech" project, Texas Instruments was granted master patents on portable calculators. Sharp put in great efforts in size and power reduction and introduced in January 1971 the Sharp EL-8, also marketed as the Facit 1111, which was...

Internal workings

In general, a basic electronic calculator consists of the following components: Power source (mains electricity, battery and/or solar cell) An office calculating machine with a paper printer. To perform the calculation 25 + 9, one presses keys in the following sequence on most calculators: 2 5 + 9 =. When 2 5 is entered, it is picked up by the scanning unit; the number 25 is encoded and sent to the X register; Keypad (input device) – consists of keys used to input numbers and function commands (addition, multiplication, square-root, etc.) Display panel (output device) – displays input numbers, commands and results. Liquid-crystal displays (LCDs), vacuum fluorescent displays (VFDs), and light-emitting diode (LED) displays use seven segments to represent each digit in a basic calculator. Advanced calculators may use dot matrix displays. A printing calculator, in addition to a display panel, has a printing unit that prints results in ink onto a roll of paper, using a prin...

Calculators compared to computers

The fundamental difference between a calculator and computer is that a computer can be programmed in a way that allows the program to take different branches according to intermediate results, while calculators are pre-designed with specific functions (such as addition, multiplication, and logarithms) built in. The distinction is not clear-cut: some devices classed as programmable calculators have programming functions, sometimes with support for programming languages (such as RPL or TI-BASIC). Typically, the user buys the least costly model having a specific feature set, but does not care much about speed, since speed is constrained by how fast the user can press the buttons. Thus, designers of calculators work to minimize the number of logic elements on the chip, not the number of clock cycles needed to do a computation. For instance, instead of a hardware multiplier, a calculator might implement floating point mathematics with code in read-only memory (ROM), and compute trig...
