Hello, I bought a G3 Clamshell Ibook today and I don't know how to connect to the net with it. So I did some reseach (btw I know nothing about Mac's nothing at all. This is my first one!!) and there is something about an Airport card. So my question is how do I check to see if my computer has it. If it does then how do I access the net. If not, please, please tell me there is another way to get wireless on the thing cause I don't think I can install a wireless card on a computer. I would not even know where to begin.
