Just prior to its release in early 1985, AppleBus was renamed AppleTalk. The system had a number of limitations, including a speed of only 230.4 kbit/s, a maximum distance of from end to end, and only 32 nodes per LAN. But as the basic hardware was built into the Mac, adding nodes only cost about $50 for the adaptor box. In comparison, Ethernet or Token Ring cards cost hundreds or thousands of dollars. Additionally, the entire networking stack required only about 6 kB of RAM, allowing it to run on any Mac.
