Econet

Econet was Acorn Computers's low-cost local area network system, based on a CSMA-CD serial protocol carried over a five-wire data bus, intended for use by schools and small businesses. It was widely used in those areas, and was supported by a large number of different computer and server systems produced both by Acorn and by other companies.

Econet software was later mostly superseded by the TCP/IP-based Acorn Universal Networking (AUN), though some suppliers were still offering bridging kits to interconnect old and new networks. AUN was in turn superseded by the Acorn Access+ software.
