touchdown fever optical rotary joystick (ikari like) spinner specs
rockin_rick:
Does anyone know anything about the touchdown fever optical rotary joystick? Like what the pinout of the spinner is? How many pulses per revolution? What the electrical specs are for the pulses (e.g. low pulses/high pulses)? Can this be connected directly to a opti-pac or opti-wiz or TT2 opti-wiz?
Thanks,
Rick

Man, that seems like a simpler design than the Happ....
Crowquill:
Have you checked it against the wiring for an Ikari LS-30?
According to the manual that I found at crazykong.com, this joystick is SNK part number LS-40. Surprisingly the manual doesn't give the pinouts though.
EDIT: Just noticed that in the Wiki it states that the Touchdown Fever sticks are actually optical. It also states this though:
The Touchdown Fever games used a Happ Optical rotary, which is basically a Happ Super with the encoder wheel and optics added to the bottom
Maybe Touchdown Fever 2 did, but that definitely doesn't look like a Super. It does match the pictures in the manual.
If that's the original wiring harness, Red and black should be 5V and Ground respectively leaving the other two to be the signal and clock wires. That makes sense as that would match the pinouts for the optical boards on Happ, Atari, and Wico trackballs.

Thanks, I hadn't yet been able to track down a manual. Also never heard of that site - there's some good stuff there...
I'm not sure about assuming the red and black, though. Makes sense, but I've seen way too many games where red and black were not pos and gnd while some other colors were.
I'll try looking for LS40 info.
