I was checking the AROS archives, and there isn't much there. I did see an image file for VMware, though, so that might make it easy to setup in a virtual environment.
My main system is an AMD Athlon 64 X2 5200+ 2.6GHz. It runs Windows 95 and 98 fairly decently on Virtual PC. Heck it even runs XP decently too. (Tried Vista; not impressed.)
I'm guessing that AROS will run just fine for me under VMware.
