LCGuy--good theory on that. They probably were dirt cheap by then so the schools could buy them in bulk for next to nothing. I have reason to believe the 12" RGB monitor was also kept in production longer than we think, not only in Australia but in other parts of the world as well.

Charlieman--I think the extra parts theory is why Apple made SEs into 1991. It also, as I mentioned in my stickied thread in the compact forum, may explain why early Classics used a different CRT connector. It also explains the LCIII issue.
