AAUI transceiver for 10BASE2 with cable
AAUI transceiver for 10BASE-T
Two AAUI 10BASE2/10BASE-T combo transceivers (Linksys MACT2T and LL8-LEENET-C) and an AAUI dual 10BASE-T transceiver that is actually a three-port hub (Farallon)

Apple Attachment Unit Interface (AAUI) is a mechanical re-design by Apple of the standard Attachment Unit Interface (AUI) used to connect computer equipment to Ethernet.[1]: 1  The AUI was popular in the era before the dominance of 10BASE-T networking that started in the early 1990s; the AAUI was an attempt to make the connector much smaller and more user friendly,[2] though the proprietary nature of the interface was also criticized.[1]: 8
