Alright, so we are missing 17 which looks pretty much exactly like 10 and 16 and the others. 18, 19, and 20 are GND. 21, 22, and 23 carry 32V when needed, but since I do not have a voltage divider, I didn’t measure that. For line 24, I don’t know. It’s a wide line, so it carries some higher wattage. I’ll have to scope that again before using the logic analyses. I may well be logic GND.
