So, I bought some touchscreens from Digikey and the $30 controllers to go with them because they have a "PS2" mode.· I thought it was going to be easy to get this going with the Prop...
Well, it wasn't so easy.· It uses some non-standard communications format.· But, I was able to get enough from the datasheet to get·this modified driver going.·
It works pretty well now.· We have two 19" versions that we stuck inside regular LCD monitors.· We did have to modify the bezel a bit so that it didn't touch the sensitive part of the touchscreen.
Anyway, here's my driver and test program:

That is very cool !
Any pic's of this project ?
I wanted to try this as a project, but right now too much on my plate.
Did you run into any problems getting the touch screen to handle touch inputs ?
What are the screens you bought from digikey and the controllers Part # ?
I have completed my breadboard SD card and monitor but to upgrade to a touchscreen. "WoW" !

I made the PS2 cable myself...
We've installed in two type of monitors, but the Planar PL1910M was the easiest of the two.· Here's pics:
