Just joined the club today! Excited to have a system 11 game!
Mine works besides the displays. It has been narrowed down to a bad displayed driver. I can't get the machine to go into attract mode and take credits. I was able to do it by randomly pressing sequences of the adjustment buttons and then it worked and took credits and played games. I have seen some posts about this issue so I will try to hunt those down and see the solutions.
I'm missing the revolving light as well.
