BBC Microcomputer
     
        A series of {6502}-based personal computers launched by {Acorn
        Computers} 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.
