I'll check it out, thanks.

Basically, I'm interested in assembly language programming on those
platforms. So if they ran in an emulator, that would be ideal, but I wouldn=
't
mind a couple of real hardware boxes if there's no software alternative.

BTW, have you guys any experience with emulators/gxemul? It doesn't
cover sparc but claims to implement a complete arm and powerpc
machine, at least for the corresponding netbsd ports.

Thanks,
