I used to work for a cable company called Cablelink in Dublin in the 1990s.
Cablelink tested the Discret system in the late 1980s, which had been intended for use to launch the Premiere Movie Channel on the cable network. However, the deal did not proceed, and a couple of years later Cablelink changed to the Cryptovision system to launch premium channels from Sky.
Before I left Cablelink, I salvaged some equipment that was being scrapped. I have a Discret headend encoder and a few decoder units that were used for parts. The encoder still powers up, but there is a fault somewhere in the video circuit.
I would love to get the encoder working, but I don't have enough technical knowledge to repair it, so I am offering either:
1. To pay someone with the technical knowledge to get the encoder working again.
2. To trade the encoder and decoders for a unit that someone can build for me that simulates the Discret composite video and audio encryption.
I can provide pictures of the equipment on request.
