Good to know, the reset switch on my High Speed doesn't work (but the other two do) so I will trace it physically back and make sure there isn't a break in the wire somewhere along the line.

As for setting free play on Space Shuttle, it is not in the manual. I had to Google it when I reset my settings to factory.
From Ed Cheung's site:

From Usenet, figured out how to put the game in free play mode. Surprisingly, this is not in the manual. The way to do it is to change 'Function 18' (Maximum Credits) to zero.
With all diagnostic buttons UP.
Press 'Advance' until 'Ball' display reads 18.
Press middle diagnostic button DOWN.
Press 'Start' button until 'Credit' display goes to zero.
Power cycle game to clear book keeping mode.

Keep us updated on your progress.

That is great to hear! You are going to love this game, tons of fun to play. I feel like it bridges the gap between older, more traditional pinball and the modern mode driven games.

You're making me want to pick your brain on this intermittent problem I'm having where High Speed sometimes kicks a second ball into the shooter lane after one ball is locked... but I don't want to muddy up this thread.
