A series of 6502-based personal computers launched by AcornComputers Ltd. in January 1982, for use in the British

Broadcasting Corporation's educational programmes on

computing. The computers are noted for their reliability (many

are still in active service in 1994) and both hardware and

software were designed for easy expansion. The 6502-based

computers were succeeded in 1987 by the Acorn Archimedes

family.
