I picked up this EMCO brand joystick a little while back in a lot of stuff, and can't find much information about it. It's a dual Apple/IBM joystick, with a switch on the bottom. Then there are 4 pegs that look like some kind of adjusters sticking out of the bottom. They aren't for centering/trimming though, as those adjustments are on top of the stick. The pots measure just shy of 1Meg across, which seems odd to me. And the switch for Apple/IBM mode seems to switch in or out 2 resistors. I didn't have time to trace everything out to see exactly what is going on. The stick seems to work OK, just printing the PDL numbers in basic. Its a little twitchy, the pots could probably stand to be cleaned.
Does anyone know anything about this joystick? How can 1Meg pots work in this? And what those pegs are for? I assume they are some kind of adjustment, but the little diagram next to them doesn't make much sense. It also says ON/OFF next to each one. And they go up inside the joystick box. Maybe some kind of physical restriction? But then the ON/OFF notation on the bottom of the case don't make sense.
