In the newsletter Vol. 31 No. 4 Jeremy Jago showed an inspired bit of lateral thinking in the article "New Display Method". The outcome of which is on a CRT display you have two images, one positive, the other negative. See CRT Jeremy 1.gif.
Thinking further, the negative image, although novel, is pretty useless. So I thought about using that time of the negative image to provide a waveform function. See CRT Face 1.gif.
To the left of the positive image is displayed the waveform of the video complete with cursors marking sync, black and white levels. The cursors are shown in blue, but of course would be green on a conventional scope tube.
I have shown it on a round CRT face as rectangular ones weren't around in the period. Neither were transistors, but I'm going to take some licence there.
My question is this....would there be any interest in this?
