    JPM IMPACT with Video hardware

    driver by Phil Bennett

    Games supported:
        * Coronation Street Quiz Game
        * Cluedo (3 sets)
        * Hangman
        * Scrabble
        * Trivial Pursuit

    ROMS wanted:
        * Snakes and Ladders

    Known issues:
        * I/O documentation for lamps, reels, meters etc is possibly incorrect.
        * DUART emulation is very simplistic, in progress.
        * Digital volume control is not emulated.

        * During the attract mode of Cluedo, just after the camera flash,
        the camera colours go screwy and proceeding text is printed behind
        the camera. Is it a TMS34010 emulation flaw or original game code bug?
        For now, the GAME_IMPERFECT_GRAPHICS flag remains.
