A test AirPort card (11b)

Seen on X, something quite surprising related to 1990s AirPort cards.

It’s a PC Card used to connect another card, such as a Type III card into a Type II slot. Or – in this case – an AirPort card into a standard slot for easy access to the card, I suppose. As a reminder, AirPort cards are essentially PCMCIA (16-bit) cards, and the adapter may have been modified.
