I know the wheel turned considerably faster for Chromacoder than for the CBS fs standard. I also know that the interim step scanned the line top-to-bottom rather than side-to-side, that is, the image that the fs camera delivered to the three NTSC cameras was, although right side up, being scanned at a 90 degree rotation.
Sorry, I know I'm not explaining it well and I can't seem to locate the detailed article I read (a long time ago) that explains the technical aspects in depth.
