That’s not a CRT?
I'm referring to the glowing digits above it and to it's right. One reads "9.1913" and another reads "00230.12".
Also, looking at the CRT scren, I don't think there were big enough screen buffers in those days to capture fine detail as appears to be displayed on that screen.
I'm thinking that the display on that CRT is generated by aiming a video camera at a piece of paper somewhere.
