alespn got it. ABC bought Ampex BC-100 cameras in 1967 for sports and we are seeing one. It is a two tube effort with a backpack. One backpack was for live video via cable. The other option was a microwave xmtr option with batteries. But the best part is the two tube operation. It was a L/G tube and a R/B tube which was pushed by a field-sequential spinning disc with R/B filters. It's 1952 again. The R/B signal went to a delay line then to be re-inserted with the L/G. First via an optical disc recorder then upgraded to a giant quartz crystal delay in a huge cabinet. The internet can explain this better than me. The Ampex brochure makes no mention of spinning discs. This may explain some of the RGB stutters in the above photo. Goldmark must have been laughing.
