Picked up a "was working before I moved it, now plays blind" Tempest recently. Reseating the edge connector on the board got it to fire up, and it's playable - but the screen has some irregularities and was wondering where I should start.
Basically some of the lines on the boards are too long (or short), the screen image in general is too large, the words on the bottom of the screen are folded over, and when it shows the Tempest logo in attract mode it has a curve to it (and is definitely too large - you can see a slight burn in the monitor to where the regular size Tempest logo should be). I've reseated the chips on the board and replaced "big blue" and it made no difference.
Here's a link to 3 photos of the issue:

Not sure if I should be messing with the X Y settings on the board or looking at other issues?
Thanks!
