Terminator 2 hiscore

I brought my wife with me to the game room on the way home from shopping. She got a couple of games on Hot Shots while I was playing Terminator 2.

I had a great first ball, with approximately 115 millions. But then it all went downhill, and I drained the two next ones very fast.

Anyway, I ended up with 120,380,800, which is my highest score since I got T2 up and running again.

I noticed a problem, though. I used to have an error with the left flipper not registering on Bride of Pinbot. Of course the flipper moved whenever I pushed the button, but the game wasn't noticing that I did. For example for the extra ball lane change, or when entering initials after a good game. Only the right flipper button worked.

As you may remember, I swapped the power driver board between these two games, and now the problem has moved to T2. Suddenly I can't go left in video mode or when entering my initials. I was convinced that the cause was on the cpu board up until now, but it's the power driver board. Seems I have some troubleshooting to do.
