The difference between an AUI 15-pin transceiver and an AAUI Apple transceiver other than the connector used is Apple's AAUI port furnishes 5V power, and the AUI port furnishes 12V. If you have a hub with a thinnet port, that will be easy to connect to if you get a couple of Ts, a 50-Ohm terminator for each end, and a piece of 50-Ohm coax. Unless your card has a bunch of video RAM chips and a Brooktree DAC, don't plug a monitor into it! There were video + network combo cards, but this may not be one. If the 15-pin connector has a sliding latch, it's AUI for sure.
