AirPort Extreme Card
Background
Corresponding with the release of the AirPort Extreme Base Station, the AirPort Extreme Card became available as an option on the current models. It is based on a Broadcom 802.11g chipset and is housed in a custom enclosure that is mechanically proprietary, but is electrically compatible with the Mini PCI standard. It was also capable of being user-installed. Variants of the user installable AirPort Extreme Card are marked A-1010 (early North American spec), A-1026 (current North American spec), A-1027 (Europe/Asia spec (additional channels)) and A-1095 (unknown). A different 802.11g card was included in the last iteration of the PowerPC-based PowerBooks and iBooks. A major distinction for this card was that it was the first "combo" card that included both 802.11g as well as Bluetooth.
