I know this is an old thread, but I have a TC1100 and I'm thinking of trying to add a touch screen to it, I have some doubts though.
Does soldering the touch panel to the keyboard connector affects the keyboard use? If I attach the keyboard would it work at same time than touch panel, or will only one of them work? Or none of them work?
Another doubt is what happens when I use the pen instead the finger? The OS will receive two signals one for the Wacom and another for the touch panel (which is resistive and so it would react to the pen tip touch)? Or is the OS smart enough to listen to the Wacom interface only?
