    Skeleton driver for gambling (?) games running on hardware manufactured by 'Minivideo'.

    Probably manufactured in Italy since PCBs' solder sides are marked LS, which stands for 'lato
    saldature' (solder side in Italian).

    All dumps are missing the HD6473258P10 internal ROM. This chip is also used in Tecmo's V Goal Soccer as a MCU.

    Devices:
    1x  HD6473258P10 at u14 - 16-bit Single-Chip Microcomputer with undumped internal ROM (H8/325)
    1x oscillator 20.000MHz at xt1
    1x oscillator 8.000MHz at xt2

    ROMs
    3x TMS27C040

    RAMs
    1x M48Z08-100PC1 at u37

    Others
    1x 28x2 non-JAMMA edge connector + JAMMA adapter
    1x trimmer (volume)(R34)
    1x 2 legs jumpers (JP3)
    2x 3 legs jumpers (JP1,JP2)
