I just registered here when I found the topics about Grendel's gameport to usb adapter.
10 years ago I wanted this specific JS, and recently I was in a junk shop and found one for $3!!

But I need it to work on USB. I found out that this model (based on part no.) shipped with a gameport to usb adapter. I also found out that this adapter is really only a wiring from game port to usb pins, and the JS figures out whether it's plugged into game port or usb and sends data appropriately.
I don't have one of these adapters, and have spent over a week trying to figure out the wiring. I have even found people on the net mentioning what pins are supposedly used (and they are contradictory), but they haven't worked for me. I have even read the patent and that didn't refer to specific pins.
I was hoping one of you with one of these adapters could quickly use a multimeter and find out which pins are used. You guys seem pretty cluey so I probably don't have to tell you how, but you will probably need a female usb adapter connected to nothing so you can get to the pins. Then stick a wire into the gameport pin holes and see what connects up.
Thanks a lot!
