I'd like to find some cheap digital I/O cards with simple and well-documented interfaces and then try to get them working with Python. The parallel port is great, and widely available, but it's not exactly state-of-the-art and not convenient for controlling or accepting input from many devices at once.
How about the PC joystick port? Can't get much cheaper than that! And it's also very well documented. ;-) There are 4 digital inputs and 4 analog inputs. The analog inputs actually aren't very good at doing analog input, but they can easily be used as digital (pulse) outputs. I also found this site with a lot of dedicated interface offerings: http://www.vernier.com/mbl/index.html Brent
