I'm having some issues with an Atari XE keyboard and I'm not sure what to make of it. It's one of those fold over Mylar jobs with the extra plastic piece in the center.
I plugged it in and the only key that worked is the HELP button at the top. None of the other keys respond while in basic or in the keyboard test app.
I took the keyboard apart and found that some of the traces were looking pretty corroded so I took some rubbing alcohol and cleaned the traces up best I could.
I then took a multimeter and traced the, errrr..traces all around the board to make sure they had continuity. I specifically traced the space bar key and a couple others and they all tested ok.
I plugged the keyboard back in and still nothing. Not one single key responds except the HELP button which takes me out of the keyboard test app.
I expected that at least ONE key would work to at least let me know that the Mylar sheet is indeed the issue. Since I can not seem to get a response from anything other than the HELP button (which, ironically, is of no help - haha) I'm not sure what the issue is. I don't want to purchase a new Mylar insert if that isn't going to resolve the issue.
Does anyone have any advice on what else I should try?
