Museum of the Game® & International Arcade Museum® Forums

Hello,
i am new here, i am located in the middle of germany. I am a pinball guy since many years. Some time ago i found a Williams Defender Arcade prototype in really nice shape, complete but not working.
I read many things about this Williams technique. I fixed many things (ribbon cable, ram, reset and watchdog circuit), but it wont run. I hope to find some help here. I will post another thread for this.
Thanks
Dennis
