EtherTalk

EtherTalk is an implementation of the AppleTalk protocol over Ethernet that was developed by Apple Computer for its Macintosh product line. It gradually fell out of use as Mac OS X transitioned to.

History
EtherTalk 1.0 was first released in mid-1987 for the Macintosh II computer, which featured NuBus slots to accept early Ethernet cards. It gained wider usage as Apple introduced its Macintosh Quadra line in October 1991 with proprietary AAUI Ethernet connectors, which was carried over into early Power Macintosh models. The "beige" Power Macintosh G3 switched from AAUI to Ethernet in November 1997. Apple eventually phased out support for old AppleTalk-based protocols by Mac OS X 10.6 (Snow Leopard).
