me too, I was able to get reception at both Mulsanne and Arnage but it was not easy and not really worth the effort. Now you mention it Oldtimer I remember those screens too, although only for the first couple of times that I visited. And you are right, they were upto date, easy to stand and didn't allow themselves to constantly wonder off the subject, or start talking about cricket.Yes it would be brilliant if they were re introduced.
They're still available in the ACO members' stand. All working on test day.
