The Chromacoder cameras used the field sequential method, but that was about it. Chromacoder =/= CBS field sequential. They scanned 525 lines at 180 fields per second, 60 of them red, 60 of them blue, 60 of them green. The raster was rotated 90 degrees so the scan lines would run vertically so as to reduce the moire patters when converting the result to NTSC. The output from the camera was then fed in a round robin fashion to one of three special CRTs operating at 27ish kV with a specially formulated P1 phosphor, one tube for red, one for green, and one for blue. Each CRT had a camera tube aimed at it, and the output of the three camera tubes was used, along with a storage tube, to develop an NTSC signal.
