Pole Position wheels with an Opti-Pac - A Mini HOWTO
trcroyle:
When I tried (and I just confirmed it with an extra board) all I got was a slight "jiggle" without the modifications.

Ah fine.
But are the boards compatible? ie if you have a pole-position machine with a broken original board, can you replace it with a complex version?
If you can I would expect both to work with an optipac?

I haven't had this problem unless there was a bad connection (with different boards).
The symptom you list is what happens if one of the sensors is not connected or broken. It could be a bad chip, resistor, diode, cap, or broken weld/short. I'm guessing it's a short with all that grime around the chip.
OTOH, I could be wrong about these specific boards, as I never had one of those.

I believe I've read elsewhere that the later boards send additional information, I assume by varying the output voltage (what else are all those extra resistors for?). I don't think the optipac is capable of reading anything other than a pretty solid 5v signal, but I could very well be wrong about that.

If the boards can be swapped, then I doubt it. The signal these boards send out is simply a series of 'pulses'. Technically it's a 2-bit Gray encoding (If I recall the term correctly). It's quite simple, but a lot of optical devices use it.
