===AppleBus networking===
The Macintosh team had already begun work on what would become the [[LaserWriter]] and had considered a number of other options to answer the question of how to share these expensive machines and other resources. A series of memos from Bob Belleville clarified these concepts, outlining the Mac, LaserWriter, and a [[file server]] system which would become the [[Macintosh Office]].{{sfn|Sidhu|Andrews|Oppenheimer|1989|p=xxiii}} By late 1983 it was clear that IBM's Token Ring would not be ready in time for the launch of the Mac, and might miss the launch of these other products as well. In the end, Token Ring would not ship until October 1985.<ref>{{cite web |url=http://www.techfest.com/networking/lan/token.htm |title=Token-Ring Technical Summary |archive-url=https://web.archive.org/web/20120422020240/http://www.techfest.com/networking/lan/token.htm |archive-date=22 April 2012 |url-status=dead |at=Section 1.2}}</ref>

Jobs' earlier question to Sidhu had already sparked a number of ideas. When AppleNet was cancelled in October, Sidhu led an effort to develop a new networking system based on the AppleBus hardware. This new system would not have to conform to any existing preconceptions, and was designed to be worthy of the Mac – a system that was user-installable and required no configuration or fixed network addresses – in short, a true plug-and-play network.{{sfn|Oppenheimer|2004|loc=Slide 10}}{{third-party inline|date=June 2012}} Considerable effort was needed, but by the time the Mac was released, the basic concepts had been outlined, and some of the low-level protocols were on their way to completion. Sidhu mentioned the work to Belleville only two hours after the Mac was announced.{{sfn|Sidhu|Andrews|Oppenheimer|1989|p=xxiii}}

The "new" AppleBus was announced in early 1984,<ref group="N">AppleBus is mentioned by name in Steve Jobs' introduction of the Macintosh at the Boston Computer Society meeting in 1984. It appears just after the 7:20 mark [https://web.archive.org/web/20140126180506/http://techland.time.com/2014/01/25/steve-jobs-mac/ in the video].</ref> allowing direct connection from the Mac or Lisa through a small box that is plugged into the serial port and connected via cables to the next computer upstream and downstream. Adaptors for [[Apple II]] and [[Apple III]] were also announced.<ref name="jb">{{cite magazine |first=Jim |last=Barimo |url=https://books.google.com/books?id=lC4EAAAAMBAJ&pg=PA45 |title=Apple, waiting for IBM net, links micros with AppleBus |magazine=[[InfoWorld]] |date=26 March 1984 |pages=45–46}}</ref> Apple also announced that an AppleBus network could be attached to, and would appear to be a single node within, a Token Ring system.{{sfn|Bartimo|1984|p=45}} Details of how this would work were sketchy.{{sfn|Bartimo|1984|p=45}}
