Is there any way to add AirPort to a Power Mac G3 model?
No Power Mac G3 models — Platinum/Beige or “Blue & White” — have internal support for an Apple AirPort card (802.11b). However, “Blue & White” Power Mac G3 models can be configured with 802.11b or 802.11g wireless networking by installing a compatible PCI card. Site sponsor Operator Headgap Systems sells an 802.11b/g PCI card compatible with a “Blue & White” Power Mac G3 running MacOS X 10.3 and higher for less than US$25 including shipping within the continental US. Site sponsor Other World Computing also sells a variety of inexpensive options. Older Platinum/Beige Power Mac G3 models can be connected to a wireless network via a wireless ethernet bridge. Please double check to ensure a particular wireless solution of interest is compatible with both your Mac and your operating system.
