Dose anyone know if its possible to power the joystick optics through a 5 volt encoder like a cheap easyget controller?I'm messing around with the ideal for a mame cab and figured it might work if I can run down all the input and outputs .I already have the data sheet for the LM339N chip and all ground traces are good along with all resistors I did find one bad diode and I'm currently waiting on some new ones to arrive.I don't know if the chip is any good but I have a few of those on the way as well. I need to know if there is more than one power source coming into this board, from what I see it looks like the joystick and lights might get there source from another part of the system other than the optics board,they do share a ground.I guess to make this a simple question I should say ,is there anyway to use this optical joystick with a windows pc by plug and play?I'm not using the original stick or leaf switch with lights just a Satans Hollow stick and switch as a substitute for a Disk of Tron . Thanks for any insight and help.

Ok it's been nearly 20 years since I converted mine, so keep that in mind... details might be off/fuzzy. The optic pcbs need voltage to operate but the actual signal they send back is within tolerances of most input boards/avrs. You just need to tie to that common ground with your avr and have the wires that go back to the pcb go to the various inputs of the avr.

Thanks for the response, I was kind of thinking it might work out something like that I'll give it a shot once I get the diode in place.My concern is the way the board was laid out I know where the voltage is coming in for the main board but not for the joystick layout it's separate . Its like this lll llllll the first three go to another pin out that the joystick connects to, it looks like this l lll and its to the left of the three pin out like a kitty corner position, those are traced together by the circuit board and grounded with the circuit board but no voltage unless the first three pin out has a hot that feeds the 4 pin that's kitty corner to it, so if that's the case than there would be another voltage loop coming into the board for the joystick and the lights that the game operates in the joystick as you play,another board to control the lights as you fire.

Download the manual. Look for the control grip assembly on page 51. The pin out is there.
