Hello Dale, your picture doesn't seem to have come through, but
I guess we can manage without it. A G4 v2.1 is the 7450 ("G4e")
version, if I'm not completely mistaken. That said, the other G4
(or even the G3) version will run without damaging your computer,
just a bit slower. However, your Mac is very short on memory with
only 256 MB. TenFourFox will probably run with that, but
unsupported, and at times will be really slow.
