===AppleTalk Phase II and other developments===
A significant re-design was released in 1989 as '''AppleTalk Phase II'''. In many ways, Phase II can be considered an effort to make the earlier version (never called Phase I) more generic. LANs could now support more than 255 nodes, and zones were no longer associated with physical networks but were entirely virtual constructs used simply to organize nodes. For instance, one could now make a "Printers" zone that would list all the printers in an organization, or one might want to place that same device in the "2nd Floor" zone to indicate its physical location. Phase II also included changes to the underlying inter-networking protocols to make them less "chatty", which had previously been a serious problem on networks that bridged over wide-area networks.{{sfn|Oppenheimer|2004|loc=Slide 34}}

By this point, Apple had a wide variety of communications products under development, and many of these were announced along with AppleTalk Phase II. These included updates to EtherTalk and TokenTalk, AppleTalk software and LocalTalk hardware for the [[IBM PC]], EtherTalk for Apple's [[A/UX]] [[operating system]] allowing it to use [[LaserWriter]]s and other network resources, and the Mac [[X.25]] and [[MacX]] products.

Ethernet had become almost universal by 1990, and it was time to build Ethernet into Macs direct from the factory. However, the physical wiring used by these networks was not yet completely standardized. Apple solved this problem using a single port on the back of the computer into which the user could plug an adaptor for any given cabling system. This '''FriendlyNet''' system was based on the industry-standard [[Attachment Unit Interface]] or AUI, but deliberately chose a non-standard connector that was smaller and easier to use, which they called "Apple AUI", or '''[[AAUI]]'''. FriendlyNet was first introduced on the [[Quadra 700]] and [[Quadra 900]] computers, and used across much of the Mac line for some time.{{sfn|Oppenheimer|2004|loc=Slide 36}} As with LocalTalk, a number of third-party FriendlyNet adaptors quickly appeared.

As [[10BASE-T]] became the de facto cabling system for Ethernet, second-generation [[Power Macintosh]] machines added a 10BASE-T port in addition to AAUI. The [[PowerBook 3400c]] and lower-end Power Macs also added 10BASE-T. The [[Power Macintosh 7300]]/[[Power Macintosh 8600|8600]]/[[Power Macintosh 9600|9600]] were the final Macs to include AAUI, and 10BASE-T became universal starting with the [[Power Macintosh G3]] and [[PowerBook G3]].
