In the late 1960s, the Burroughs sponsored "nixi-tube" provided an electronic display calculator. Burroughs developed a range of adding machines with different capabilities, gradually increasing in their capabilities. A revolutionary adding machine was the Sensimatic, which was able to perform many business functions semi-automatically.
The ten digits of a GN-4 Nixie tube. A Nixie tube (English: / ˈ n ɪ k. s iː / NIK-see), or cold cathode display, [1] is an electronic device used for displaying numerals or other information using glow discharge. The glass tube contains a wire-mesh anode and multiple cathodes, shaped like numerals or other symbols.
ANITA Mk VIII. The ANITA Mark VII and ANITA Mark VIII calculators were launched simultaneously in late 1961 as the world's first all-electronic desktop calculators. [1] [2] Designed and built by the Bell Punch Co. in Britain, and marketed through its Sumlock Comptometer division, they used vacuum tubes and cold-cathode switching tubes in their logic circuits and nixie tubes for their numerical ...
From 1965 to about 1971, Wang was a well-regarded calculator company. The dollar price of Wang calculators [17] was in the mid-four-figures. [18] They used Nixie tube readouts, performed transcendental functions, had varying degrees of programmability, and used magnetic core memory.
In 1911 there were 78 Burroughs models ranging in price from $175 to $850 and Burroughs introduced its Burroughs Class 3 visible adding machines based on the Pike design. Also in 1911, Burroughs introduced a key-driven calculator that looked very much like a Felt & Tarrant Comptometer. In 1912, the Burroughs Calculator was $150.
The last ANITA machine with a Comptometer keyboard was the ANITA mk 10 introduced in 1965, still using cold-cathode switching tubes and that will be replaced in 1968 by the ANITA mk 11, a 10 key machine. Sharp's first all transistor desktop calculator, the CS-10A COMPET, introduced in the summer of 1964, also had a Comptometer type keyboard.
Some types contain a source of beta radiation to start ionization of the gas that fills the tube. [5] In some tubes, glow discharge around the cathode is usually minimized; instead there is a so-called positive column, filling the tube. [6] [7] [note 2] Examples are the neon lamp and nixie tubes. Nixie tubes too are cold-cathode neon displays ...
A few different versions of the fourteen segment display exist as cold-cathode neon lamps. For example, one type made by Burroughs Corporation was called "Panaplex". Instead of using a filament as the incandescent versions do, these use a cathode charged to a 180 V potential which causes the electrified segment to glow a bright orange color. [6]
