I am wanting to know if anyone remembers the old light pens that used to turn your tv into a tablet screen. They look like the pen style barcode scanners but rather than read barcodes, it would send the position of the pen back to the atari and then the atari would plot the lines that you draw on screen.
Here is a picture of one if you dont know what im talking about http://www.mr-atari.com/afbeeldingen/XLXE%20boxes%20carts/lightpen%20boxed.jpg
Anyhow back to my question. Does anyone know if you can get one of these for modern computers?
The reason I ask is because I just purchased a new jap import subaru with an lcd screen in it. The touch screen part only works for the gps which cant be used in nz. I have managed to hook up my laptop to it using the composite output and a low resolution in ntsc mode. Now i just need to send mouse signals back to the laptop rather easily.
