    PQFP 100(?)pin chip marked "SP-BE0"
    PQFP 100(?)pin chip marked "SP-BH0"
    PQFP 100(?)pin chip marked "SP-AF0"
    Lattice pLSI 1024-60LJ B604S03
    6116 SRAM    x2
    AS7C256 SRAM x8
    jumper pack (12)
    dsw8         x2
    Xtal 24.576 MHz
    Xtal 21.47727 MHz
    volume pot
    27c801       x4
    two empty eprom sockets

    It's SNES version of KI with few mods (removed copyright messages,
    extra code for coin input, etc).

    256 bytes of RAM ( mapped to reserved area) are shared with some
    device (probably Lattice PLD) used for handle coin inputs and dips

    Data lines of eproms are bitswapped.
