These look like [PCMCIA] cards but actually aren't. They are used to upgrade "AirPort ready" Apple computers (both desktop and laptop) with wireless capability. Apple's [AppleAirport AirPort Base Stations] are standard 802.11b so AirPort Card equipped Apples will work with non-Apple access points and vice versa.

The special AirPort connector on AirPort-ready Apples carries an antenna pin, which connects to an antenna built into the frame of the machine.  With a bit of futzing about, you can get a pigtail in there.



AirPort-ready, G3-based, slot-load iMacs need a caddy to install an AirPort card.



AirPortExtreme cards are 802.11g and not back-compatible with Airport slots.  Damn you Steve!
