No there is not.

Umm. Yep. Actually, we'll need to have newtons re-manufactured. And
personnaly, I'll need...., well I wonder.
>Question: Is it legal to make an emulator?
It is, I think, if it takes the ROM from the Newton. (you bought the right
to use the ROM, hence if you have an emulator, you can use the ROM in the
emulator if you are not using the Newton).
However, the Newton programs are run in user mode. Hence, there may be some
parts of the memory which you can't access. This just means, that if I were
Apple, I would have protected the startup code, at least because it is
useless once the Newton started. And we will never be able to access this
code in such a case (except if we can find a workaround to go to supervisor
mode).
The investigations I am doing in the NewtonOS shows that if NS is not
protected at all (at least, objects can be patched), it seems that the
system is in fact *very* protected.
Anyway, Apple tried several time to start a Newton Emulator Project, but
they abandonned it.

The thing is that the non NS code is like the kernel for everything in the
NS system. Providing all an environement for a NS shell means writing all
the functions that are *not* NS, and which the programs may call or
require. It is what David Arnold does.
