Alca Electronics

Alca Electronics, styled ALCA on their products, was a British manufacturer of arcade games, starting with electro-mechanical games and later moving to video games. While they designed their own electromechanical games, most of their video games were unlicensed copies of other designs, starting with Atari's Pong, which they called Ping Pong. Ping Pong reached the UK market six months before Atari, becoming the first video game made in Europe. During their heyday, they branched out to pool tables and fruit machines and similar devices, becoming one of the larger electronics manufacturers in Manchester area.

A series of events in the early 1980s led to the rapid downfall of the company. In August 1981, Martin Bromley, former founder of Sega and now one of the company's major distributors, was convicted of VAT tax fraud and his assets were frozen. In November, Alca began selling off their machines at low prices to keep the cash flowing. In February 1982, Sega's recently formed European division sued Alca for copyright infringement over their copy of Frogger. With little money coming in, and the costs of a lawsuit only starting, the company was liquidated in August 1982.
