I have an issue with my Joust. It has some graphic glitches that appear at times. But if you fly over the glitches they will disappear. Any thoughts before I pull the chips and reseat them??
That is usually an indication of problems with the RAM, even if you're not currently getting RAM errors. Sometimes a simple chip leg cleaning of all 24 RAM chips will fix it. I'd recommend doing the 4164 RAM upgrade to it though.
Also, sometimes you can get stuff like this if you have a problem with the ribbon cable from the ROM board, but that is less common...
+1 on the convergence. I'd try the RAM, but I wouldn't expect it to fix the problems. Pic #2 is a clear example of convergence issues. You probably bumped the nexk or moved the cabinet. A good degaussing might help a liitle alse.
