I plugged mine into my Spider-man cabinet, played some Joust.
Had my hands on a cheap very abused joust a month or so ago, but walked away, now i'm wishing i had done otherwise.
GL with your search, hopefully someone comes up with some adapters, or pictures, or both.
what about using the arcadeshop panel? (looks like they might carry a harness as well (instead of an adapter))
