So, there's 5 knobs on that gun board. 4 and 5 are obvious... horizontal and vertical. What about 1,2 and 3?



I ask this, because my game is almost perfect now. However, I notice on the sides of the screen the marker bows away from the edges slightly. Both guns do it, and both gun markers bow in a bit as you go along the edge of the screen (instead of straight down, where I'm actually pointing the gun).



Could this be because I'm using a perfectly flat monitor? I'm GUESSING that maybe one of those other three knobs controls if it bows in or out.



Now, I find it hard to believe that nobody on planet earth knows what those three knobs does. Anyone have any idea where to find the service manual for this gun board?

I did some tweaking once with these knobs (maybe because Andy keeps saying don't touch them ). It seems they've some kind of trapezoid-funtion, but I'm still not sure. I'd recommend: don't touch them! You can fuck up the whole calibration forever.



If Andy has no service manual then it's kinda unlikely anyone else have.

Final update. I replaced one last sensor that looked good, but through a digital camera was flickering with a new sensor. Boom. All problems fixed. The game is SUPER accurate with both guns. Glad I didn't mess with the pots now.

Cool! And now go play!!
