Do you have any experience with parallel LCD's?
They are very sensitive, I have had three go dead from the parallel port just from using it (they were all hooked up correctly).
I have been working on a "buffer" for Parallel LCD use. It is still in the testing stages and it seems to work fine. It is based on a PIC that "passes" through data information. This should safely allow the LCD to be used for parallel use, but it is still in the testing stages.
PM me if you are interested.
