Why on earth would performance suck? The original hardware was dog

early 90's they were dog slow, their main advantage was I/O. The I/O
on a full blown system is where a modern system might have emulation
problems, still, who is going to want to emulate rows of disks and
tape drives. The various PDP-10 emulators have shown that you can
get decent performance out of a 32-bit CPU running a 36-bit emulator.

That's an
interesting question. I can't think of that many machines
with a hardware ring architecture, and it's not something that can be
easily faked with more traditional architectures. It would be a fairly
invasive "port".
Probably the simplest thing would be to make a CPU emulator, and run it in
that. Then you can be totally architecturally agnostic.
Performance, of course, would suck.
