ISEN-ASTC-L is a service of the Association of Science-Technology Centers
Incorporated, a worldwide network of science museums and related institutions.
*****************************************************************************
We have a sub-contractor who claims to have had numerous problems
with Happ Trackballs being troublesome (bearings not engaging
smoothly); I've had the opposite experience. Nevertheless, since he
is responsible for the interface, I'm wondering if a) you've had
mechanical issues with the Happ controller, other than routine
cleaning and b)if you've used other panel mount trackballs with
success that I can direct him towards.
We're using a Mac in this case, so it needs to be USB compatible, and
it needs to have at least one pushbutton, or pushbutton interface.
Thanks....
