Unfortunately, testing the OPTI-PAC interface with the Happ trackball (and Fultra spinner which uses the same PCB) has revealed a problem. Happ have added extra circuitry to the optical PCBs on the trackballs. They are not just an optical sensor (unlike the Wico and Suzo trackballs). This means some more work is needed to interface these to the OPTI-PAC. I'm working on a solution but in the meantime have amended the website to indicate not to order this interface for use with Happ trackballs. (actually for these trackballs that new Hagstrom interface looks pretty good I have to say!)

Cheers

Andy
