Acorn - The Econet: A Local Area Network - Data Link Layer and Physical Layer Specifications
Econet was Acorn Computer's local area network system, allowing its computers to communicate to one another. It was supported on the System 1, Atom, BBC Micro and all other post-Atom Acorn machines excepting the Electron, A3010 and the cancelled Phoebe.
This document contains an introduction ot the system and its specifications. It is unclear whether it was a published document or not.
From the abstract:
'This document has been compiled as a design reference document. It describes the subnet communication layers of Econet which includes electrical characteristics and communication protocols. The intention is to provide adequate information concerning the behaviour of the data link layer while leaving individual implementations to exploit whatever technologies are appropriate. In addition, the specific implementation used by Acorn Computers is described in detail as an example of one such technology. To this end a large proportion of the report is dedicated to describing the implementation of the MC6854 Advanced Data Link Controller, which is at the heart of the data link layer used by Acorn Computers.'
