A look at the PyPy 2.0 release
'course, probably not a major focus for either developers or users at this point...
Indeed not only 32-bit

Nothing new here, as that is a limitation of the processor, not of the system (you can't run 16-bit code on 64-bit mode as you can on 32-bit mode).
But I don't actually run any windows machine, so can't test it.

Hmh. I read in a Finnish computer mag that doesn't tend to get things that wrong that it doesn't do 16-bit code. (If you're talking about running a 32-bit windows in a VM, of course that'll do it at the latest...) Actually, as for Wine, the 64-bit version was last I checked slated to run semi-similarly only 64-bit code, while you can run the 32-bit version for 16/32-bit Windows code using the host kernel's 32-bit userland facilities.
Anyway, I have no first-hand knowledge — or interest — either, was just trying to be funny.

Anyway, not much interested to know the truth either.

no 16-bit in long mode

Entering full-blown virtual 8086 mode is impossible, however.

You can get around that by playing with amd64 virtualization (i.e. run a guest in legacy mode and use _that_ to run 16bit real-mode code). If you don't have that, you are SOL - you pretty much have to emulate 8086. Instruction set is there, but address translation is incompatible.
