Yes, you are correct. There is a VLSI variant that we like to pretend doesn’t exist.(Isn't it the case that there are two possible flavours of CRTC in a beeb??)
In all seriousness, we don’t actually understand the full logic of the VLSI chip (whilst we believe the Hitachi to be mapped) - it differs in substantial ways from the other chips, although these only arise in edge / corner cases.
