Running neo sticks on your PC is easy, relatively speaking. Here's a picture of my keyboard's neo port sticking out, which sadly only works on my custom sticks (
here and
here) and the original neo stick. It's probably possible to use all the neo pads, but I'm too lazy to rewire everything.
I had also completed, but found far less useful,
this little device (See
here and
here for more pics) which proved to be a hassle 'cause it had no pass-through, and couldn't offer the other useful keys (like arrows, esc, ret, etc) so I've abandoned it. It was a PitFighter cart, FYI.
Again, if anyone's interested I'll whip up docs on the procedure. It involves some soldering and you'll want to cut a hole in your KB, but that's as hard as it gets.
