For sale: a vintage Apple M0329 Ethernet Thin Coax Transceiver 14-pin AAUI connector for 10Base2. This kind of ethernet connector is found on Macintosh Quadra computers, as well as on some vintage PowerBooks, Apple Ethernet NB Cards, pre-G3 Power Macs, and some LaserWriter printers. This is what I found on Wikipedia for the AAUI 14-pin standard: "Apple Attachment Unit Interface (AAUI) is a mechanical re-design by Apple of the standard Attachment Unit Interface (AUI) used to connect Ethernet transceivers to computer equipment. AUI was popular in the era before the dominance of 10BASE-T networking that started in the early 1990s; AAUI was an attempt to make the connector much smaller and more user friendly." -- all credit to Wikipedia Contributors, last revision 24 December 2017.
