Title: Happs trackball: Why the green grounding wires?
Post by: Mugzilla on October 16, 2003, 11:27:51 pm: I installed my highlip happs trackball. The green ground wires that connect to the outside of the case in 2 places are NOT connected.

In fact, since I had to uninstall the trackball to change the ball, I took the ground wires off completely,... and it still works. Are they there for a reason? Part of some super secret circuit? Static electricity grounding?

FWIW, my 3" Betson also has a grounding wire. My wico 3" and 2 1/4" don't. [shrug] I haven't hooked the grounding wires, but I don't have a carpet floor and 100 people using the TB, building up that much static.
