Early Power Macintosh and Quadras had an AAUI (Apple Attachment Unit Interface) port (rectangular shaped) for Ethernet, which requires a transceiver

To use twisted pair cabling, you would need to get a twisted pair transceiver for the computer with an AAUI port

Some Power Macintosh computers had both an AAUI and RJ-45 port you can use one or the other, but not both

The pin-out is:

AAUI signals have the same description, function, and electrical requirements as the AUI signals of the same name, as detailed in IEEE 802

3-1990 CSMA/CD Standard, section 7
