Does anyone know how to contact the maker of the Tron Arcades to confirm availability of the Tron Arcade mod? I visited the PinballLooking site, but it's nearly a year out of date and the e-mail function doesn't seem to be working. Perhaps the maker is a Pinside member?

Thanks!

What's the secret to getting consistent credit from shots to the spinning disc? Mine has gotten to where about half the time I don't get credit for my shots. I've tried using q-tips through the metal holes to try and clean the optos, which look painful to get to otherwise. Has anyone had to trouble shoot a similar problem, or replace the optos, who would like to share their insight?

I think I've got it fixed now, but only time will tell. I took the two screws out mounting the left opto in place, tinkered with it a bit as best I could with not much access, and then reinstalled the screws. I didn't think to run the opto switch, #41, test before tinkering though. However, the beam breaks 100% in test and play since then. I don't know if that will take care of whatever the problem was long term or not. Maybe a mounting screw was loose or some foreign matter was blocking a part of the beam? Thanks for the advice.
