Hacking a Betson 3" Trackball
SirPeale:
I just got a Betson 3" Trackball. I thought I could just take off the wires to a PS/2 mouse and connect it up, but didn't know the pinout.
So, hoping someone had done something similar, I found this:

Snazzy. Problem is, I don't get most of it. I now wish I had taken electronics when I was in school.

Reading further into it it seems easier than I first thought. I'm definitely going to give this a go, but I wish I had a molex connector so I would not have to chop the existing setup.

I've noticed my RadioShack carries molex's, though I've never looked at the sizes.

Looking at the pinout for a typical PS/2 mouse:

It's difficult to make a connection between the trackball pinout and a mouse pinout. They both have six wires, GND and +5V, but for PS/2 we've got 'DATA' 'CLOCK' and two 'RESERVED'. On the trackball there is 'VCLOCK' 'VDIR' 'HCLOCK' and 'HDIR'.
I'm confused.

Wouldn't Oscar's pre-hacked mouse be a good solution here?
