Note to any interested parties in this game. I will have a populated complete Farfalla pf that I will eventually sell as well as a Devil riders complete game with battery roached boards in a rough cabinet and missing the backglass and neon. Soccer Kings uses the same board set so you might be able to swap all 3 games back and forth into the same cabinet just by switching the ROMS.

Wish this was on the west coast as I'd probably pick it up myself for just that type of project.

well good thing there were no batteries on the Devil Riders sound board as that one should probably still work.

Why wouldn't there be any sound for soccer kings. The one in the ad has a sound board. Simply swap that in as well when swapping the mpu roms.

Looks like the Farfalla/Devil Riders sound board might be backwards compatible to the soccer kings board. Looks to be the same sound generation with an unpopulated section for further improvements that never came.

Pretty easy system to work on.

Homepin even makes replacement CPU and driver boards and displays for these games.

Displays, coils and power supply all mimic the Bally set-up pretty closely.

David Gersic's website is pretty complete as far as documentation and free-play roms and even has spare parts.
Leon made test ROMs
Clay even had a short Zaccaria repair section.

Probably the only hard part would be sourcing the 2650 processor and the sound board amp and misc sound issues.

Oops look like Homepin gave up on the replacement ZAC MPU and somebody else did it instead.
