Tie a Happ trackball on a mini-pac, how?
(1/2) > >>
speeder:
I just got the totally awesome happ trackball.

And the surprisingly small mini-pac.

Fitting the buttons are easy, all parts needed for that came with the mini-pac, but the trackball I have no idea on how to put it on the mini-pac.
BobA:
If you have the new minipac the wiring for the trackball x and y is shown on the LHS of the minipac.  You will have to rig up a wiring harness to connect to the trackball connector or cut the wires and make a direct connection.

What about connecting a HAPP trackball to the "old" MiniPAC?

Thanks.

BobA:
Here is the wiring diagram for the old minipac.

D_Harris:
That's a terrible diagram. The following one is better.(Though the optical connections can be made more clear). I think someone here drew it up.
