yeah, after some sleep, the next morning I started looking at the wires coming from the mouse.
There are only 5.
One for ground, one for voltage, then 3 more.
In those three would need to be a clock signal, movement data, and mouse click signal.
Just a guess.
So there aren't wires for left/right, up/down like I was hoping.
I was trying to figure out a way to turn the board upside down, but there wasn't enough room, so I may go with extending the decoder wheel later, thanks Kremmit.
I'll just stick with the software option originally mentioned by Vizzinni, but if you can find the info on the logitech software, I'll try that Sev.
Thanks all.
