I have info for Paul regarding how to make The NCR touchscreen kiosk work.
Here's what you need to do. The system is designed to run on windows. The entire system WILL run on linux....but not the touch controller. If you look at you picture marked cpu w/ fan....lok at the chip under the fan. It says AMI microtouch - excalibur. That is the controller chip. It sends its info through the PS/2 mouseport, inside the motherboard, and reqires a cutom driver to do so. For that you need Microtouch touchware 5.64....a windows program. When you install it, it will ask if you want a serial, ps2 or USB connection. Select PS/2. follow the rest of the instructions, when you restart, it should work.
