Did some more on this set, specifically looking at and adjusting the matchup of the luma and the decoded chroma as presented on the CRT display. Found I needed an extra 90 nSec of delay on the luma to get the match looking better.

a football game down line graphic (green-yellow-green transitions), and below the football captain symbol on the uniform (blue-yellow-blue transitions), showing that the chroma-luma group delay timing is reasonably correct.

The setup I used between the CM7000 and the CTC108 circuit board (the video line driver circuit is to buffer the delay line from the unterminated feed to the CTC108 board)
