[sci.electronics] What can you do with a PC game port?

Hi all,

    I've got one of those "multi-IO" cards in my 386 box, and one of the
connectors is a game port.  Is it possible to do anything with this game
port other than use joysticks, etc?

    There are two analog inputs (resistance), correct?  Suppose I connect
a photocell across one and the temperature probe from a microwave oven
across the other; would I then be able to read the room temperature and
light intensity (assuming I've worked out the scaling of values)?

   Could someone mail me a list of the pin descriptions for the game port?

   Is it possible to OUTPUT anything through the game port?

   ...anything else I should know?
