You can measure resistance from about 0 to 200K (which is what a joystick is), or current from 0 to some few mA, or various other things. Also, you *can* output through a game port, in an odd way: when the joystick positions are sensed, a pulse appears. I did an article about game ports for PC Tech Journal around 1985. This should be in your library. It's just the beginning, but it does give some nice temperature- and voltage-measuring circuits. Oh, by the way, you have +5V and ground at the game port connector. You could power all sorts of peripherals with it. -- ------------------------------------------------------- Michael A.
