Does anyone know how to correctly wire an old "Track and Field" Trackball up to a PS2 mouse? The trackball says its by Wico. I've read several topics, but everyone seems to be using Happs trackball optics (expensive!). I figured out the PS2 mouse from reading up, but I don't know where to connect the wires to the pins on the trackball optics.
I know there is a 5v, ground (both y-axis and x-axis have one each which are eventually connected), 2 signals for the x-axis, and 2 for the y coming from the trackball. Is there a diagram out there somewhere to show how to wire these to a PS2 mouse hack? ???
(By the way, I'm new to making controls, and BYOAC has been an EXCELLENT ;D resource!!! I built my own control pannel-2 ball-head joysticks, 6 buttons each side, player 1 and 2 start. Coin 1 and 2 are set up like a pinball style on the sides. I'm using an I-PAC usb interface. My uncle gave me a Track and Field control panel, and I'd like to hook up the trackball to my panel!)
Any help would be great!! Thanks in advance!!

Thanks a bunch Bob, your write up really helps. I still have two questions though.
1) How do I find out where to connect the +5v and Gnd wires to the mouse circuit board? (is it directly where the ps2 wires connect to the mouse?: there are four wires there)
2) Do I hook both red wires to the +5v and both black wires to the gnd?
By the way, my wires are Blue, Purple, Green, and Yellow. I'm assuming my purp is your brown.
Thanks!

The PS/2 mouse connector has the following pinout when looking at the connector on the back of the computer:
6 Pin PS2
1 DATA
2 No connection
3 GND
4 +5V
5 CLK
6 No connection
The PS2 on the computer is numbered as follows:
6 5
4 3
2 1
When looking at the connector on the mouse it
is nmbered as follows:
5 6
3 4
1 2
I just followed the lines from the connector back to the mouse to establish the +5V and GND
I connected the +5 and GND of both optical boards to the +5V and GND of the mouse. I checked this with a Volt meter to make sure.

Thanks BobA! That's exactly what I needed! :) I'll give it a try as soon as I get some solder.

Just wanted to say I got my trackball hack working! ;D It is a little slow in windows, but I can jack up the sensitivity. Marble Madness, Centipede and Missile Command all played great when I turned up the sensitivity.
1 question:
Is there any way to set the analog sensitivity for all the trackball games at once, or do I have to set them one by one (what I did for the games listed above)?
Thanks again! :)

Glad to hear that you got it working.
Under Windows you can increase the speed of your pointer under Mouse in the control panel. I am not sure how this will affect your overall performance if you are using a windows based MAME or how it interacts with the individual game sensitivity settings.

No. :(
Well, I guess you can edit each game's driver in mame source and recompile, but mame is not designed to set global analog settings. :-\
