That first widescreen would have been the CTC-172 chassis. I had one of those too. Also knew Joe Clayton who went onto to Direct TV fame. I designed the analog circuitry in the wide screen module that turned a CTC-170 into a wide screen set. One of my challenges was making the two pictures in the side by side mode look the same. Two different chroma demodulators, one created by a PIP chip with only 6 bits while the main channel was 8 bits. I had to use a D/A to align the offset on the video and chroma clamps. When I was younger I hunted down all the artifacts and history I could from the older RCA engineers from the pre-war days. I guess no one will ever care about recent television history.
