    Hardware description (from targets.mame.net):

        In the late 80s, Arcadia collaborated with Mastertronic to create their own
        ten-interchangeable-game arcade platform called the Arcadia Multi Select system,
        using the same hardware as the beloved Commodore Amiga computer.

        (In fact, the Multi Select's main PCB is an A500 motherboard, to which the ROM
        cage is attached through the external expansion port).

        Reportedly the system was also (or was originally) supposed to have been released
        in two five-game Super Select versions--"Arcade Action" and "Sports Simulation"
        -- but no specimens of these have ever been seen.

    NOTES and TODO:
        - To get into service mode, hold down F2 before pressing a button after
        the 'INITIALIZATION OK' message. Pressing F2 during game brings service
        mode also.
