I don't know the recommended minimum, but I had an PIII 733 Mhz, 256 MB lying around. I put an old NVidia card in it and AROS boots easily on that one, under 40 sec, and warm reboot about 10 sec. The OS runs ok, no slowdowns with opening closing applications or windows etc.
I not that privileged that I could have tried out that browser
yet but I don't expect it to be sluggish at all on that hardware.
