I know, but without getting too technical, I thought that "simulate" was the
easiest word to understand for people who might not know what an emulator
does.  Saying that an emulator is something that emulates isn't really a
very good definition.  It's like if someone asked you to describe the color
red and you said it was kind of reddish.

How's this for a better description:  A Mac emulator is a program that
creates a virtual Mac inside your PC - it allows you to run the Mac OS and
Mac software because it translates all the instructions meant for the Mac
processor, and converts them into instructions that the PC's processor can
understand.  It does not replace the Windows OS (although you could make it
look that way by running it in full screen mode) it's just another Windows
program.

Well, that's something to keep an eye on, but are there any Power Mac
emulators that you can download right now?

If an emulator was perfectly written, and the programs were run on it only
used standard programming techniques, then I'm sure it would work perfectly.
But it's been my experience (Using Virtual PC and several other emulators)
that the emulator will always be missing some sort of functionality of the
real system that I need (like supporting AppleTalk) and the software I want
to run on it will always use some sort of non-standard trick to do it's
thing, that works on the real hardware, but confuses the heck out of the
emulator.

As far as speed goes, I once heard that you needed a computer ten times
faster than the one you wanted to emulate to get comparable speed.  I know
this is a very rough estimate, but it does make sense for an emulated
computer to be slower than a real one, as every instruction has to be
translated from an instruction for one type of computer to an instruction
for another type.

In their PC-Only school, perhaps the boxy beige 5500 would fit in better
than the colorful iMac.  =o)
