AirPort card adapter for iMac G3
Enable your iMac G3 to accept AirPort cards, and you can be surfing without wires in no time! Just connect the AirPort Card into the Adapter cradle and then install the entire assembly into your G3-based, slot-loading AirPort ready iMac. Other Apple products, such as iBook, Power Mac, and PowerBook as well as new G4-based iMacs, do not require this Adapter kit. With AirPort-enabled Macintosh systems, it is a snap to exchange files or play multiplayer games at data transfer rates of up to 11Mb/s. And because AirPort uses radio waves for communication, it can even work through walls.
