Finally. The cabeling is done for the control panel and amazingly has tested out fairly well with WinIPAC. A few of the original buttons are flakey and I may be replacing them in the future, but onward we go on the build. The wiring seems AOK so I felt comfortable in cinching them up with wire ties to straighten the whole thing out.
My buddy Stan (also a fellow OHMSpace member) pointed out that I should be doing a shared grounding ring for the buttons and joysticks instead of consolidating the individual grounds...Stan didn't point this out until the panel was mostly wired. The lower portion of the panel with coin drops and player start buttons has been wired with the shared grounding ring. I blame Stan for the inconsistency, he should have been watching me closer.
