Any one know how to connect a Happ rotary optical joystick up to the opti-pac.
Andy should have instructions on
www.ultimarc.com. The Happ optical rotary uses the same opto boards as their trackballs.
Also with the i-pac can you connect two joysticks upto the same port and use either one, ie a 4 way joystick and a 8 way joystick or in my case a t-stick and a happ rotary joystick.
Absolutely, as long as you realize that they will work together. I.e., if you are playing using the T-stick and you (or your opponent!!!) accidentally (?) bumps your rotary stick upwards, the character will move upwards. If this is a problem, you could either use an I-PAC/4 to gain more inputs, or use either a pair of DPDT or a 4-pole rotary switch to select between the joysticks.
