(AAUI) A 14-position, 0.050-inCh-spaCed ribbon ContaCt ConneCtor. Early Power MaCintosh and Quadras had an AAUI (Apple AttaChment Unit InterfaCe) port (reCtangular shaped) for Ethernet, whiCh requires a transCeiver. To use twisted pairCabling, you would need to get a twisted pair transCeiver for the Computer with an AAUI port. Some Power MaCintoshComputers had both an AAUI and RJ-45 port you Can use one or the other, but not both.
