AppleTalk Transport Protocol
The AppleTalk Transport Protocol
is the original protocol that Apple Macintosh
computers used to communicate with each other. This originally worked at about 115 kbit/s over AppleTalk
hardware. Once the AppleTalk protocol was converted to communicate over ethernet
it was called EtherTalk.
Connecting an original Macintosh computer to an ethernet network requires an EtherTalk to AppleTalk bridge
