Hi, I have an older Turbo Twist 2 spinner and board from circa 2007. Everything works great, but I just picked up a U-Trak trackball and would like to use the same board interface for both. I am looking at the Optiwiz 3 from Groovy Game Gear. Anybody know if I can hook up a U-trak to the Optiwiz 3 using just the stock trackball harness? Posed a few question to Randy from GGG and never heard back. Thought I'd ask here. Any help is truly appreciated. Thanks. |

Put the four data lines in the UTrak Y-axis 1x4 Dupont housing. Put the 5v lines in a 1x2 housing or two 1x1 housings and put the ground in a 1x1 housing. - You might have some of these 1x1 or 1x2 housings on computer or breadboard jumpers. - If you don't have any of them, put the 5v lines in the X-axis 1x4 housing (leave the two un-filled positions hanging over the PCB) and put the ground line on the ground pin without a housing.
