While they're in there, how about reducing the "IN THE PYRAMID!, IN THE PYRAMID!" speech?

You're right, if you own such a machine you're getting used to pressing the flipper key to start a game and to prevent the speech ;D
About the STTNG... Man, that was a long story, still not fixed!
The pin kept blowing up LM339's on the 16 opto and on the 7 ball through on an irregular basis. I noticed it was the same ic every time: U3 on the 16 opto and U1 on the 7 ball through. I tried moving the machine off from the carpet that somethimes was quite static, no solution. I replace the molex connecting the 7 ball through because the power led on the PCB was flashing sometimes, not good. But: no solution, it's still eating a couple of LM's a week.
Now yesterday I found a loose connector on one of the PCB's that drives the cannon motors. So it might be induction current from that bad connector? I disconnected it and played 3 games without blowing stuff up. I keep my fingers crossed...
