Hi
you might be interested to know that EMI in the UK had a go at a field sequential colour (UK spelling!) camera. see
http://www.tvcameramuseum.org/emi/ex...2/seqcolp1.htm
This was an experimental colour wheel camera using a similar arrangement of 3 CRTs and 3 cameras looking at them, as sort of standards converter. I have a write up on it somewhere but it was much the same as the CBS one.
There were many defects and a lot of electronics to go with it all, but at that time there were not many choices for colour cameras the only good (ish) was the BIG 3 IO option.
