More investigation needs to occur to see exactly what happened but I ordered a 20A toggle switch to replace it. The power switch does nothing, so the switch either must have failed with the circuit closed, or was non-working and the game must have been wired to turn on/off only at the plug.
In any case, that was a bit of relief as the brains, from what I know, are in a good spot. Something that can't be said about most projects. I also see that a lot of the connectors have been reworked, so at some point, someone cared enough for this game to put in time, money and effort. Good news to me since that's about half of the cost of the game It appears to have the original driver board but looks clean. After initial set up, I looked at the boards and connectors and see that it came with a Rottendog power supply and a Ni-Wumpf MPU, unbeknownst to the seller (not a pin person). This will be my first System 1, so hoping that some knowledge and experience from Bally SS can carry across. As with my other project games, this thread is meant for me to document fixes, vent frustrations, and get some help as I work through bringing this Joker Poker back to life. This game has been on my list for some time, and despite it being a 'common' game that showed up occasionally, they were usually out of my price range, but one popped up for sale recently that was listed as non-working, from a classified ad and I was happy to have been able to snag it.
