Hi there, My current corral of Macs has a 1 GHz PBG4, 350 MHz Blue G3, and a dead 266 MHz PBG3 (Wall Street). I'm planning on getting Panther RSN, and I believe it will be great on the PBG4. But has anyone here tried it on older machines, i.e. G3s? I'm looking at rotating the PBG3 out to either an employee of my publishing company or a friend in need, and I don't want to burden them with a slow OS. OS X 10.0.4 was slow, almost to the point of unusable (to me) on the PBG3. I didn't get 10.1 or .2 on there before its power supply croaked, but anticipate they'd be slightly better. Perhaps a CPU upgrade would aide it? Thanks, haaz.
