A home computer created by Acorn in the UK in the early 80s. Basically a cut-down version of the BBC Micro, mostly compatible apart from less channels of sound and the lack of teletext display Mode 7. Never really as popular as the Spectrum and Commodore 64, but still had a loyal band of followers and it's own magazine, Electron User, which had such joys as building your own weather station and the ten-liner section, how complex a program can you fit into ten lines? Eventually faded away, Acorn went on to produce the Archimedes line of computers, based on the ARM chip, used in a number of mobile phones. Rather incestuously ARM have now bought Acorn.
