Actually the PA is the best example there. Alpha I believe has a functional-enough QEMU port to do real work and m68k has Aranym which I've used to bootstrap m68k within the last 18 months. Hell, I think Aranym actually ran faster than the last shipping real hardware! > I'd say that all ports not in maintainance mode should be at least > secondary archs as we can expect maintainers to be around to keep it > at the quality level we expect for secondary targets.

I could live with that. jeff
