Actually, the video circuitry in the Plus and earlier is nearly identical to early 9" B&W security monitors. So to say that it is analogous to a Lexus is stretching it quite a bit. It's more like a circuit someone found laying around and stole for use in the Mac (or used a reference circuit for the CRTs they had chosen).

I found a small stash of replacement Mac CRTs several years ago which were originally sold as service parts for security monitors. The attached circuit board is very similar to the Mac analog board.
