The only Ethernet hardware products Acorn made were Ethernet interfaces. Ethernet interfaces fall into 3 categories:

Acorn also produced a number of software products that used Ethernet, In particular AUN (Acorn Universal Networking) products such as the Level 4 fileserver (AES50), Intertalk (AES72) and Omniclient (AES75). The Acorn software products are currently out of the scope of Chris's Acorns, athough I may revisit that when I have completed cataloging my hardware.

In addition to Acorn, a number of 3rd parties produced Ethernet interfaces for Acorn computers. The interfaces are documented here and in the Upgrades section of Chris's Acorns.
