I'm falling in love with my G4 lampshade. If any of you have an old Airport card, I'd love one! I don't care how fast it is, if it's cheap enough. Just a few webpages on top of playing movies and I'm a happy camper.
You can install a lucent silver wave card and it works just like airport although some hacking of the card itself may need to happen. I installed one in my 17" imac 800 and it works great! But if you can find an original for a decent price I would do that
My Avatar is my Macbook Pro with an original Apple Sticker.
I use a 15" Macbook Pro, Mac Pro, and a Core 2 Duo Mac Mini. I also use an Apple Cube dual 500 with a radeon 7500 and 1.5 gigs of ram.
Depends on which iMac G4 you have. Later 1.0 ghz and above had Airport Extreme, USB 2.0, used different ram, etc. Both types of cards are available for $20-40 or so used now...
Another viable and usually inexpensive solution is to use a USB wireless card- available in B, G and N speeds. The B sticks will not work with OSX. The G & N sticks will be limited to slower speeds(B speed) on USB 1.0 machines, full speed on USB 2.0 machines, and work only with OSX- no OS9 drivers. That won't matter if you have later model-they won't boot into OS9 anyway.
