Network Prover

The Network Prover by DiRen was a small black box which fitted in line with a network cable. The LED flashed in various frequencies to indicate the network was idle, transmitting or waiting, a very helpful device for those who made use of the QL network. The Network Prover had a 3.5mm socket into which the main network cable plugged and a short lead extended from the box to the QL network socket.
