Are the legacy screens Full Colour? i dont know exactly what they are, but make sure theyre colour.

For a touch screen, there are basically 3 parts:
1)the screen, just an lcd screen.

2)the touch screen overlay: this goes over the screen (or is built into the screen casing) and is basically the sensor that detects where your finger presses. There are several different kinds, the 2 most popular are capacitive and resistive.

3) the touch screen controller: this connects to the touch screen overlay and then either connects to the serial, ps2 or USB port. The controller basically translates between the overlay and the computer, so that the computer sees it as a mouse.

You can usually buy any of the pieces on their own, or all in one big package. You do need to make sure that the overlay and the controller are compatable, as there are no standards for them. you can usually get a generic (3M) overlay to fit onto most any screen, but you need to make sure of the exact dimensions for it to fit.
