I actually have a couple of old PCI ethernet cards that have both standard RJ45 connectors and BNC coax connectors. Does that mean I actually have something rare?
Probably not. I had a whole drawer of them up until a couple of years ago. I chucked most of them (possibly with the exception of one, "just in case"). You'll probably find hundreds of them piled up in the "spares" rooms of loads of IT departments.
Not as rare as the handful of PCI ethernet cards I have with a RJ45 and a DB9 connector. 100BASE-CX, ethernet over STP, used for a very brief period of time so people could reuse their Token Ring wiring plant for Ethernet.
DB9. As I said, it's so customers with a wiring plant based on Token Ring STP (aka Type 1) could use ethernet at the end points without running new wiring.

As I understand it the BNC connector is not rare, it's the AUI connector that's hard to find.
That's the 15-pin VGA-ish connector in the card pictured.

Is it DB9, or AUI? (AUI is 15-pin, and is the card required for this story)
