4. The WindowServer was new code and broke source and bincompat with the old #DisplayPostscript based window server

5. Classic was a para-virtualized environment running almost the entire classic OS. New code was written to support things like FS and Network sharing, etc. As I recall developers were first demo’ed classic running on #NuKernel at labs at #WWDC, and it was ported to Mac OS X shortly after that.
