I took out the intellivision for a spin last night and after a while noticed the controller was getting a little unresponsive. Being in a good mood I took it apart for some cleaning... no luck
Multimeter comes out... testing...
well looks like the plastic cicuity thingy has a bad area in the fold, where 8 (yes 8) lines are just barely connected (I did on continuance test to find the area, and then pulled out a magnify glass).
I tried to tape tin-foil (tested for conductivity) over each line, but they kinda flake out - the fold seems to push it out of place after a few minutes.
Anyone have any tricks up their sleeves? (Short of finding a new system, I've never seen one in the wild)
