Had the fortune of going to Portland, OR and seeing an arcade there called Ground Kontrol a while back. It was almost like stepping into the '80s. Games seemed to be kept in good shape, in general. Impressive little arcade.
Tron and
Discs of Tron were in good condition and worked quite well. Check out their list of games... and they had a bunch of pinball machines upstairs:

Here's a video someone did showing Ground Kontrol at 6:57; with Discs of Tron and Tron briefly seen there 8:45 - 8:55. Not the best of videos, but should give an idea:

Recommend this arcade to any Tron fan who goes out that way. It's a bar, too, though... so there may be some sort of age restriction. But it's open late! And they had a line of people trying to get in on a Friday or Saturday night. I think that'd be pretty common there. It's okay during the day, too, though, as I think they darken/tint the windows so it's relatively dark inside.
