My panel now is similar to the SUPERCADE PANEL except that it isn't two levels and there is a real Tron stick instead of an analog flightstick. I mis-judged the placement of some buttons and one stick, so I find it to be not as player-friendly as I wanted. With all the new stuff I bought I am going to come up with an interchangeable control panel system.
Here are the panels I could populate with all this stuff:
1. Discs of Tron
2. Ikari Warriors
3. Williams Multigame (also for asteroids)
4. 2 Player Fighter panel with a 4 way joy in the middle
5. Trackball panel for GoldenTee, Shuffleshot, Schuuz, & WC Bowling
6. Star Wars Yoke Panel
7. 360 Steering Panel
8. 270 Steering Panel
I had considered making a rotating panel like 1up, but there's too much crap. I would just build 8 different machines, but the computer and monitor costs would be too much (plus my wife would throw me out of the house).
