Thanks to forum member Talon2000, my Tempest boardset is doing its thing. He was a pleasure to work with.
In keeping with my Tempest's theme, apparently work needs to be done on every part, from transformer on up. We've reached the opto board on the spinner. Opto appears to be dead, since its gettings its 5V and putting out nada when interrupted. I cleaned it, tried viewing it through an IR sensitive camera (nothing), etc.
Been doing some extensive reading, but unclear to me what the best solution is. The best replacement opto parts seem to be a farichild part (H22a1) that is no longer available.
Suggestions? Can I just pick up a trackball sensor from Bob Roberts, and switch up the wiring?
