Actually, I beleive (confirmed by the VT100 tech manual and schematics)
that you have to sync the external video to the VT100 and not the other
way round. In other words, you take the signal from the Video Out socket,
extract the sync, then use that to sync the video source (camera or whatever)
that you feed into the Video In socket

It works perfectly well with the VT100 set to 60Hz, provided that is the vertical
rate of the external video source.
