Mouse Hack Issues

[crashball]

I picked me up a suzo trackball from Ultimarc and am attempting the mouse hack interface like on Lusid's web site.  My problem is I can't get it to work after soldering the connections to the mouse PCB.  I tried to test it before removing the light reader diode thing (not the technical name i know) just by holdin the wires to the soldered contacts and was able to get some movement.  After removing the sensors and soldering the wires, i get nothing.  I think I am using the right kind of solder but the package is long gone. Is there anyway to tell what kind I have?  If I remove the solder on the connections it looks as if the metal or shiny ring around the hole is not longer there, like it got rubbed off when I tried to get the solder off. I think the etching may even be coming off on one, I probably baked it.  The PC still detects the mouse and the buttons still work, but no movement.  I Think I have toasted 2 mouse PCBs in one way or another and snapped a 3rd in half trying to get it out of the case. Would the wrong kind of solder not conduct a connection or is my conenction bad?  Any tips from those who have done it would be appriciated.

Oscar sells a premade mouse hack for a good price. Check his webpage

It's a touchy hack.  Some mice just don't work, and I only tried it with Happ's sensor board. 

I think you've killed enough rodents.  Time to buy an interface.

Try this one from Minwah's site. Worked for me.

Minwah's hack works fine, but you need some pull up resistors to get the Ultimarc t'balls working:

Ah, I was not aware of that. I used an Imperial TB.
