So it was pinned for colour but only used mono ?There was another Philips monitor in the same or similar case. I've seen it in both Green and Amber phosphors. This was also used on the Beeb when colour was too expensive. I can't remember the number now though.That was almost certainly composite though - but it was such a common monitor it's quite possible there was a separate-sync version. > > > Is it 12"?

Mine has 13" visible so probably a 14" tube. And although the mono might have been smaller, that case shape is so embedded in my memory that I think they must have been 14" too - a 12" version would have looked amusingly miniaturised. > >
