The Acorn Electron is a budget version of the BBC Micro educational/home computer introduced by Acorn Computers Ltd on 25 August 1983. It has 32 kilobytes of RAM, and its ROM includes BBC BASIC v2 along with its operating system.
The Electron was able to save and load programs onto audio cassette via a supplied converter cable that connected it to any standard tape recorder that had the correct sockets. It was capable of basic graphics, and could display onto either a television set, a colour (RGB) monitor or a "green screen" monitor.
For a short period, the Electron was reportedly the best selling micro in the United Kingdom, with an estimated 200,000 to 250,000 machines sold over its entire commercial lifespan.
