Trackball mouse hack

If the question is about soldering to pins vs an open hole, then I'd DEFINITELY choose the open hole!  If you do that, then you just put the tinned wire through the hole, apply heat to it and the pad, and flow some solder onto the two such that it is mechanically strong.  Soldering to pins works just fine so I guess it's just preference.

And yeah, I would be concerned about interference with the original transmitters installed.  Good call on just clipping them if you don't think you'll ever need them again!  I always keep that type of stuff for some reason knowing that I'll likely never find anything to do with it.   :dunno

Thanks for the help.
I've got my hands on a good PS2 mouse, but I need to use a PS2-USB connector as my PC doesnt have PS2
Does that alter things any?
Im still not getting the power part. I need to tap the ground and power wire from the trackball into the wires on the long mouse cable to get power?
Or the trackball will draw power from the main circuit board when I attack the x/y wires where the receiver chips used  to be?

I haven't done a trackball hack and have never worked with an arcade trackball beyond looking at Happs.  What I can say is that on my Atari encoder boards that fit my steering wheels, there are 5 wires on the mouse (2 for transmitter, 3 for receiver) for each axis that connected to 4 wires for each wheel (1 axis).

The mouse wires are +5v, ground (for transmitter), +5v, ground (for receiver) and signal.  I think one of the wires on the Atari board is not connected, so that means you need 3 wires for one axis or 4 wires for 2 axis.
