Williams Pinball, System 11B MPU Board Repair Part 1

Have a board from a customers Cyclone that has issues. I swapped them my board for a loaner and I will work on this one.

Thanks for watching. These are where I cut my teeth on learning board repairs. I got into the arcade business back in 1987 and the early system 9 and 11 board are what I started on.

@@bfpsa64 Williams FunHouse from 1990 would been the first pinball machine I worked on. Not sure what board that has in it but the video reminded me of it.

@Cinncinnatus Funhouse was a weird one. Early versions were 11c but it was also the first WPC version but still had the alphanumeric displays.
