  Hardware info (29/07/2008 f205v):

  Chips:
    1x missing main CPU (u1)(from the socket I would say it's a 68000)
    1x A40MX04-PL84 (u29)
    1x AD-65 (equivalent to M6295) (u9)(sound)
    1x MC1458P (u10)(sound)
    1x TDA2003 (u8)(sound)
    1x oscillator 10.000MHz (QZ1)
    1x oscillator 16.000000 (QZ2)
  ROMs:
    1x AT27C020 (1)
    2x M27C4001 (2,3)
    2x AT49F010 (4,5)
    2x DS1230Y (non volatile SRAM)
  Notes:
    1x 28x2 edge connector
    1x trimmer (volume)

  - This hardware is almost identical to that in magic10.cpp

  CPU is a MC68000P10, from the other games boards...
