Apple had a few false starts when it came to local area networks in the 1980s. In February 1983, the company announced AppleNet, which it described as a “scaled-down version” of Bob Metcalfe’s Ethernet standard. The idea was that AppleNet would offer a decentralized LAN that didn’t require a full server and could connect up to 128 Apple II, Apple III, or Lisa systems across a distance of up to 2,000 feet. Apple claimed this approach would make its LAN more affordable, with a per-node connection cost of under $500. The trade-off was that AppleNet would be slower than other Ethernet LANs.

Local area networks were a regular topic during early seasons of Computer Chronicles. In a first-season episode from 1983, 3Com’s Ethernet was still “under discussion” as a possible industry networking standard. In 1985, IBM tried–and ultimately failed–to gain control of the standard with Token Ring. Now, with this next look at networking from November 1987, the topic had grown so much in complexity that this would be the first of a two-part series. This first episode focused on networking technology for IBM PCs and compatibles, while the next program addressed the state of LANs on the Macintosh.
