Analog Game Port Interface (joystick)

[blcpro]

Does anyone know where to find the specs for the standard game port interface? This is the analog interface for joysticks, etc. I have a project with components that are very much like a joystick, so for development I want to test it out on the game port of my PC. Specifics that I am looking for are:

1) The max current draw from the interface. (Will this be a variable between different manufacturers of game ports?)

2) Details of the pushbutton interface. (is there pullup or pulldown resistors involved? Is there debouncing in the game controller or on the joystick?)

3) The limits of the analog signal. (What are the normal ranges for this signal... I would expect a range of 0 to 5V. Is that correct?)

4) Defining a generic joystick in Windows. Can this be done without any special drivers?


Any help here would be greatly appreciated.
