Page "AppleTalk" Paragraph 3

After the release of the Apple Lisa computer in January 1983, Apple invested considerable effort in the development of a local area networking ( LAN ) system for the machines.

Known as AppleNet, it was based on the seminal Xerox XNS protocol stack but running on a custom 1 Mbit / s coaxial cable system.

It was announced early in 1983 with a fall introduction at the target price of $ 500 for plug-in AppleNet cards for the Lisa and the Apple II.
