LocalTalk-to-Ethernet bridge
Encyclopedia
A LocalTalk-to-Ethernet Bridge is a network bridge that joins the physical layer
of the AppleTalk
networking
used by previous generations of Apple Computer
products to an Ethernet
network.
Some LocalTalk-to-Ethernet Bridges only performed Appletalk
bridging. Others were also able to bridge other protocols. For example: TCP/IP in the form of MacIP
