Where might I find a RiscOS3 (Acorn Arc) port ?

No clue. I remember my grandpa running a pc emulator with win95 on an Acorn
many years ago. I was very impressed that such a small box could actually do
that. For CISC machines not that hard to emulate a RISC machine. The other
way around is another story! BTW my grandpa was almost eighty years at
that time and he's become a true computer nerd doing all kinds of things
with computers only people like "us" would do!

No, actually the other way around it the easy part. Emulating a CISC on a
RISC system is easy. Emulating a RISC system on a CISC system is difficult.
Of course I am talking in terms of a _fast_ emulation. Some slow emulation
is easy in either case as one can just write it in C and run everywhere. A
fast emulation requires to generate native code. And it is easy to generate
good native code for a CISC system on a RISC system. The other way around
you already run into problems as you most likely don't have enough registers
on the CISC system to store all the emulated RISC registers in...

Then why is emulating a mac on a intel so difficult? I've tried to find out
if there is any way to run OSX on an intel machine and I haven't found one
yet!

Someone has to do it, but who would want to have a Mac if they already
have a PC? :)

Because you need the Apple firmware (aka bios) and you cannot just copy it
because that would be illegal?
Apart from that, I said emulating a RISC processor on a CISC processor is
difficult.

Google helps ... i.e. <http://www.google.com/search?q=Mac+powerpc+emulator>

If you own the relavent hardware then you can make a backup for emulation
purposes, OTOH I am sure any commercial OSX capable emulator will ship with
a rom card

Your question doesn't make sense, I'm gussing you didn't read things
closely enough. As Thorsten said, "Emulating a CISC on a RISC system is
easy. Emulating a RISC system on a CISC system is difficult."
This is why you have things like VirtualPC, but no VirtualMac. Emulating
a Mac on an Intel processor is trying to emulate a RISC system on a CISC
one.

I thought he wanted a POV port for RicsOS. There is a RiscOS 3.11 port
that runs under Windows available under the names "VirtualA5000" and
"VirtualAcorn".

You sure he didn't just have a PC card in his Arc?
That's the usual way I've seen of running PC stuff on Acorns.
