OK, thanks. 🙂
I can't see anything on You Tube with Panther, but put it on because several people said it's more stable. I will put Tiger on, but not today, because we're in the middle of a snowstorm and the electricity has been going on and off. I don't need that in the middle of an OS upgrade. The eMac did a few weird things the last two times the power came back on, so I'd best get off the computer until this is over.
It's great to have helpful people who like these older Macs too, thanks again!
Edited to add: Focus knob? Where is that on an eMac, please?
