Looks like they chopped the BBU ASIC of the SE into a pile of Video Logic crap, a Video ROM and a modicum of VRAM to put Crappy@$$ Compact Video, slightly improved by the dedicated VRAM, in there for the worst Video on a MacII ever and, barring any improvement (doubtful) in the Classics, a slightly better Video implementation than the SE's.
BIG WHOOP! Shoulda' been grayscale from day one.
