Great hacking hardware if you can get it. Sadly not available in the UK, and probably would be to dear if it was..... :dunno

it is hard to see from the pic, but the trackball pcb has a gray ribbon cable already attached that is plenty long enough to use to connect it to the mouse PCB..so the only additional wire you will need is to connect the mouse buttons.

that takes care of the golden tee trackball part, the mouse hack can vary based on which mouse you use.  there are several tutorials on line on how to hack a mouse to use with an arcade trackball.  here is a good one...

basically, you use a multimeter to locate a ground and 5v source on the mouse circuit board.  you unsolder the button switches, and the ir emitters and receivers.  it is easy to tell which receiver goes to which axis, so just attach wires from the mouse board to the proper location in the trackball...once it is all hooked up, give it a spin, if any of the directions are reversed, just unsolder and swap the two corresponding wires.  it is really pretty simple.

Old thread dig to say that this post and link helped me to perform this hack myself.  It was helpful that someone had figured out the pins on the device for me and the link answered some questions about working with the mouse.

I wired button 1 to both outside buttons and the other 2 mouse buttons are the inside buttons.  I used tape to keep my wires down, but I just kinda left the mouse board wedged in and floating.  The USB cord wraps around the plastic screw housing closest to the cord exit hole for strain relief.

Some tips here would be that all 3 of the +5v lines need to be connected on the ball.  At first, I assumed that only one was needed but that is not true.  Knowing this now, I would have routed all 3 through a small board like I did with button 1 and the ground.  This would have eliminated 2 solder points on the mouse PCB.  I could have eliminated another solder point If I'd routed direction and button ground to the same point, but I was testing directions and ended up with 2 ground points.

I learned that I am a bad guesser when it comes to picking which point will be U/D L/R.  I traced the lines to the chip but that didn't help me guess as I guessed wrong both times.  I also wasn't paying very close attention to the way the mouse rolled as I wired Up/Down to Left/Right at first - ugh.  I even ended up wiring button 2 where I wanted button 3, but that's not a big deal.

i'm glad i was able to help.  i almost forgot about this..i may have to dig mine out and try it again

You certainly left a nice trail for me to follow here.  I keep it out and it works as a mouse and trackball for my upright cab.  I was actually surprised at how much fun I had using this with spinner and flight stick games.  This really enhanced my MAME experience.

Here is an action shot:

I got one of these with the intent to use it in my first build. Never did use it. I total forgot I had it.
