: Whoops you could be right, but the optical encoder one works like a trackball/mouse.. there is no click positon.

: : An ohm is a measure of resistance, not a signal. I think what you were trying to say is that it is a variable resistor. Which is true in some cases. Other types are optical encoders (as you mentioned) and there are rotary encoders. The rotary encoders are most likely what you are referring to that 'click'.
: : : Rotary joysticks are joysticks that have a knob which rotated, there are two different types.
: : : Rotary (fixed postional), these send ohm signals to represent where the rotary postion is, as used in games like Ikari Warriors, Gurrella War, Heavy Barrell (these probably could be connected to a PC, although MAME/Allegro would need to be modified to support it, and I am 99% sure that the ohm signal would be too low for PC ports to pickup).
: : : The other type is optical rotary as used in games like Caliber 50, Downtown, Forgotten Worlds, this has an optical encoder which works very similar to a mouse, I have these and can safetly say they are easy to hook up (in MAME this functions all rotary type games, and its pretty good fun, although you don't get that nice clicky feel like Ikari warriors).
: : : I hope that helped.
