These are great hardware documents. Does anyone know where to get the specs on the T301 LCD screen and the touchscreen manufacturer or its schematics?

No but it is definitely worth contacting Velocity about those particular details since they are pretty good about responding. I don't see why they would not want to divulge the touch screen specs. While they have not been willing to share the source code for either the t301 or t10x, this should really be no problem.

Are you simply curious or with the touchscreen information could someone use this to improve responsiveness...or other characteristics?

I would like this info to fix my touchscreen. My touchscreen has become unresponsive and I have traced the problem to the touchscreen hardware. I initially thought that it was a calibration problem and updated the tablet, but that didn't fix the issue. Then I borrowed a friend's tablet and the result was unequivically a hardware issue. My next step is to try and source the touchscreen specs and trace that portion. I am pretty confident that once I have it I can fix it. I was able to source the LCD screen manufacturer for the screen. I would appriciate any help or direction anyone can provide.
