[...], but Classic is better than emulation because of
its
integration with the OS.
Um, Classic *is* emulation. Perhaps you're thinking that you can't
emulate except by emulating the entire machine? I did a VAX emulator
once that, to speak loosely, trapped to the emulator when doing a
syscall, rather than emulating the privileged side of the hardware as
well as the nonprivileged.
[...] the fact that Classic transparently maps on the
hardware, the
file system and makes the app windows part of the OS is important and
handy.
Right. It's an emulator that emulates certain aspects of classic MacOS
in more useful ways than the "Mac in a window" emulation of the whole
computer as an opaque (from outside the emulator) blob.
