Swanwick was, and still is, ringfenced by some senior engineers that have designed an ATC centre for engineers - it works just fine as far as they are concerned. The system was dumped by the Americans after spending enough $ to by West London.
By 1995 The displays had probably improved over the light grey on dark grey 'design' provided at great expense by the Royal College of Art as an engineer decided that the displays chosen by ATCO's was not good enough and he knew better! Of course, you could not see the aircraft but hey, its pretty and pleasing on the eye and apart from not being able to see the aircraft its perfect!
You guys just need to take control of YOUR systems.
