Info: (Extract from WIKIPEDIA):
A Nixie tube, or cold cathode display, is an electronic device 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.
Applying power to one cathode surrounds it with an orange glow discharge. The tube is filled with a gas at low pressure, usually mostly neon and often a little mercury or argon,
in a Penning mixture.
Although it resembles a vacuum tube in appearance, its operation does not depend on thermionic emission of electrons from a heated cathode.
It is therefore called a cold-cathode tube (a form of gas-filled tube), or a variant of neon lamp.
Such tubes rarely exceed 40 C (104 F) even under the most severe of operating conditions in a room at ambient temperature.
The early Nixie displays were made by a small vacuum tube manufacturer called HAYDU BROTHERS Laboratories, and introduced in 1955 by BURROUGHS Corporation, who purchased HAYDU.
The name Nixie was derived by BURROUGHS from "NIX I", an abbreviation of "Numeric Indicator eXperimental No. 1",
although this may have been a backronym designed to evoke a mythical creature.
Hundreds of variations of this design were manufactured by many firms, from the 1950s until the 1990s.
The most common form of Nixie tube has ten cathodes in the shapes of the numerals 0 to 9 (and occasionally a decimal point or two),
but there are also types that show various letters, signs and symbols. Because the numbers and other characters are arranged one behind another,
each character appears at a different depth, giving Nixie based displays a distinct appearance.
