And it could be damaged too.  The screen is in beautiful shape, and that might be misleading.  It could be just so far outta wack that it is calibrating the input way out of the range of the screen or something and it knows better, so it doesn't ever complete the calibration.  Once I get my hands on it again I'll give an update.  Hopefully I can make this thing useful for the first time in the 8 years I've owned it.
