Hatta Posted July 13, 2010 Share Posted July 13, 2010 I picked up this joystick for Apple II/IBM PC at the salvation army. It has quite the array of connectors. A is the standard 9 pin Apple II joystick. B is some strange 16 pin plug I'm not familiar with. C and D are a converter cable from 9 pin female to 15 pin male. And yes, they're all lettered that way. Two questions come to mind. What is plug B for? And can I expect the converter cable to work with other Apple II joysticks? There's a switch on the bottom to change modes of the joystick so I'm guessing not. Quote Link to comment Share on other sites More sharing options...

Hatta Posted July 13, 2010 Author Share Posted July 13, 2010 OK, I'm having a strange issue with it. Whenever I move to the left and release, it shortly moves to the right. This is not a bouncing of the stick itself, it doesn't move much past center. However, reading PDL(0) returns 255 for about a second or two which usually decays back to 128 after a few more seconds. Sometimes it'll stick at 255 until I move the stick again. I've already opened it up and sprayed down the pots good, which is about the extent of my hardware troubleshooting. Any thoughts as to what could cause this kind of error? Quote Link to comment Share on other sites More sharing options...

I just popped open my GS and there it was. That's an odd place for a joystick connector. It functions the same as the 9 pin game port then? Mutually exclusive with the external game port I'd imagine.

Yeah the internal game port was there in the GS for the whole backwards compatibility thing with the Apple II. This might explain it a bit better then what i could http://rich12345.tripod.com/OPHP/gameport.html just scroll down to pinouts or read to that point. but they do share some of the signals. Depending on what connection you used have you tried the other connection to see if its a connection issue causing the drift ?
