The simplest way would be to take a temperature dependant resistor of
max. resistance approx. 470 kOhm and connect it directly to the second
mouse/joystick port, just like an analogous paddle. Which pins to use
and how the software can monitor this is spreaded across several books.
Look into the Addison-Wesley RKM Hardware Reference Manual.
But note: This is simple AND VERY UNPRECISE!
