<One thing I didn't mention is that there's a pin on both the AVO and

It's actually a DIP setup on the AVO and main board of the VT100. Stp
for the most part was null functionality save for the printerbuffer cards.

You forgot the VT103 that was a VT100 with AVO using a cost reduced card.
I ahve one or two of those loose.

Older video sources like cameras were deigned to be genlocked off somthing
else and had two cables (the one I'd seen) and the sync return was usually
from the output of the GENlock/timebase to the VT100
and a TEE connector
seemed to work for that. Should work for color as well.
