    Raiden (Modular System)

    As with most of the 'Modular System' setups, the hardware is heavily modified from the original
    and consists of a multi-board stack in a cage, hence different driver.

    For this game the Modular System cage contains 8 main boards and 1 sub board.

    8086/1 red board - 2 V30s, M68000 socket for connecting to board 6/1 + 6 ROMs + RAMs.
    MOD-6/1 - RAMs, 20 MHz XTAL and  M68000 socket used for connecting to board 8086/1.
    MOD 21/1 - 24 MHz XTAL.
    MOD 1/5 - Sound board (Z80, 2xYM2203C). 2 8-dips banks + small sub board with OKI M5205.
    MOD 51/3 - Sprite board, has logic + 4 sprite ROMs.
    MOD 4/3 - Tilemap board, has logic + 4 tilemap ROMs, long thin sub-board (CAR-0484/1) for terminating the connector (it's not used).
    MOD 4/3 - Tilemap board, has logic + 4 tilemap ROMs, long thin sub-board (CAR-0484/1) for terminating the connector (it's not used).
    MOD 4/3 - Tilemap board, has logic + 4 tilemap ROMs, long thin sub-board (CAR-0484/1) for terminating the connector (it's not used).
