Well, I ended up taking two Centipede cocktails off of another local collector as a package deal. Still want that Gorf, though… Will have to come back t that one soon!
But I digress… So I have two Centipede cocktails here. One of them has a dead monitor (and a non-working board, I later discovered), and the other will not sync:
(Note how dirty the control panel is, as well as the color of the button and trackball to compare with another picture later in this post.) Checked the wiring, the connectors, adjustments/controls and nothing would get it right, so I went to capping it. Here is a picture of it half way done on my bench:
After capping it (and also doing the sync improvement upgrade while I was there), all it took was a few adjustments and the screen came up sharp and clear. This image also shows one of the rebuilt trackballs, which is now running as smooth as when it came out of the crate:
The text looks a bit blurry, but only in the picture. The screen is really sharp! You can also see a new shiny trackball at the bottom too. Next to it is a really dirty button. Here is one of the panels (from the other cocktail, because its panels are in better condition) with a replacement button and a (unmounted) rebuilt trackball after being cleaned up a bit:
All in all, not bad for about 3 or so hours of work, if I do say so myself. (3 hours for everything, not just cleaning this panel!
Now, that other cocktail… that one is gonna be a bit harder…
