Quoted from pinball4ever:According to IPDB, it uses a lot of Zaccaria boards and parts (except the sound board). That's definitely good news:
"Notes: Uses Zaccaria CPU, power supply, driver boards, and 8-digit displays. Uses a Tecnoplay specific sound board."

Also, the ROMS are available for download if needed.
I'd also make sure it has all the boards shown in this pic:

And if the machine didn't have the boards, you would pass for $100? I would load it up and not ask a single question.
