It will work, but only if you write a device driver for it. Parallel I/O (or any direct hardware access for that matter) is made much harder in NT by the HAL (Hardware Abstraction Layer). One of it's functions is to keep NT portable accross different processors, so hardware access cannot be made execpt through a device driver that makes calls to the HAL. I'm not sure if anyone has written a driver for an LCD screen yet.
