After leaving my machine to sit for a few weeks while I worked on other house-related projects, I finally got around to finishing all the maintenance I had been meaning to do.
-Took apart the whole playfield and gave it a good cleaning.
-Replaced the mylar leading out of the left bumpers to the left drain lane (just above the red car). It was starting to completely lift off and collect dirt, which is apparently common with this particular one.
-Waxed the whole playfield.
-Repaired some stripped holes for wood screws.
-Added a set of plastic protectors and replaced the broken rocket plastic.
-Rebuilt my clock so that it sat right-side up.
-Installed the pinbits gumball light mod.
-Re-adjusted the rocket kicker a tad higher so that it wouldn't brick the ball.
-Right slingshot switch readjusted to match the left's sensitivity.
This game freakin' zooms now and is dialed-in perfect!
Now I can work on my backbox lighting mod. I designed a nice little circuit that, when plugged into the backbox's GI wiring, will flash an LED with a period of 3 seconds and a slow turn-on/turn-off. The idea is that I'll hook one up to each of the 6 black bulb slots. That way I can put any LED with a 555 wedge base in the slots and it will blink with a nice "starlight twinkle" effect. Already soldered together 3 PCBs, so I'm about halfway there.
