Awesome possum! Now I can start cross checking stuff.
My color switch card does nothing when connected, so I just threw a few bucks at it and replac d these parts... Let's see.
Bought the same chips with the same intent of replacing them on a (seemingly) non-working ColorSwitch... but then never found the time to do it
Anyway I guess the new ColorSwitch pcb project could be a place to look at, for finding some answers, even related to the pinout we're all trying to figure out; for instance your question:
have been bugging me for a couple years alreadyAlso, does Ground need to get connected to each of the various grounds at the DB15, or is one sufficient? (Pin1+Pin6+Pin13)
