I recently purchased a used TT4 with the optional display. I got a new PS/2 style keyboard from Amazon, it works with my PC no problem. However, I cant figure out what's going on with the TT. It will not recognize any input from the keyboard. I've re-loaded the current firmware and even tried the previous version. The display shows location information and received messages no issue. Am I missing something? Has anyone had compatibility issues??
