The Acorn Econet is a bus based network that runs over 5 wires. Two wires are used as Data +/-, two wires are used as Clock +/- and the fifth wire is used as a common ground.
Original Econet socket boxes are reasonably difficult to come by these days and they used punch down connections inside to attach each socket box to the network bus. Whilst the original Acorn design for the socket box is fantastic for fixed networks in business or school settings, I needed something a little more flexible that would allow me to build an ad hoc Econet network and allow me to extend or reduce the networks size relatively easily and so, I built my own.
The wiring for a socket box is straightforward
