I spent a lot of time playing Bally Twilight Zone at the Munich Maker Lab a few years back. I still miss the tungsten bulbs which lit the ball consistently, as opposed to LEDs which tend to "blink" rapidly (at 60Hz?). It makes the ball much easier to track at high speed, and has such a nostalgic soft glow which gently fades off into nothing.

I also miss reading the manual and fixing little things every so often.

It looks like this machine has either moved on from MuMaLab, or was never listed in the first place.

It would be nice to be able to filter machines here by what kind of lights they use. I imagine most places tend to use LEDs to save on electricity. At least that's been my experience checking the barcades I've found from this site.
