Designed by Acorn, the Electron was designed to be a budget version of the BBC Micro. Acorn designed a single, customized ULA chip that was able to emulate the BBC Micro hardware, but it did feature a few limitations including the sound being limited to only one channel (as opposed to three on the BBC Micro) as well as the inability to provide teletext mode.
The Electron came with 32 kb of RAM, Acorn MOS operating system and ROM BBC_BASIC v2. Programs were loaded via an audio cassette and with a supplied converter cable, could be used with any standard tape recorder with the correct sockets. graphics output options included TV set, colour (RGB) monitor or green screen monitor.
At one point, during it’s peak, the Electron was the third best selling micro-computer in the UK.
