- The amiga can use analog joysticks, if the software knows how to read them.
- (No drivers are included in the system libraries).
- One or more of the "intro to amiga" booklets has the required pinout.
-
- The joysticks must be variable resistors somewhere in the range of 470K to
- 1M; they are read by charging a capacitor through the variable resistor and
- seeing how many video scanlines it takes to cross a threshold. Its a
- resistance measurement, not a voltage measurement. In this reguard, the
- port is a lot like the old Apple-2 joystick port. (I think PC game cards
- may acutually have a A/d converter measuring voltage, but I'm not sure).
