Hello.
The display uses a BIOS driven digitizer.
It uses the same protocol a light pen equipped graphics card uses.
What happens in a CGA graphics card with a light pen is that the screen
location is scanned, 525 lines, interlaced, this is vectored by the page
memory and sent out as an analog signal.
A light pen is a device with a fast photosensor, as the line is scanned, an
output pulse is created by the light beam, this is corrolated with the beam
position and the vector sum.
The graphics card can then be polled for this information.
Hence, no real driver as such, just a device called " pen "
Windows needs a driver but the hardware support is native to the 730T.
LINUX might have light pen support, I will need to check.
