tt - NICE WORK! I've updated the pinout with your info. We've accounted for all 86 leads that go from the CPU to the daystar slot.

I've examined the capacitors on the various non-se/30 daystar adapters I own, and it looks like they're merely charge "buffers" intended to sustain +5v at all times. I'm going to assume the capacitors on the IIcx adapter do the same. If you can, scrutinize the 3 resistors close to the CPU socket next.

Once we figure out where the resistors connect, it's safe to assume the rest of the red pins aren't used
