Hi Serhii,
I was searching also the same thing for my terminal emulator PlatoLives
I found your post while I'm in the process of reconstructing lowercase chars because
uppercase ones you can find in the 4010 manual. I found a YouTube video from the vintage
Tek museum
https://youtu.be/dcoL5lT3tbY?is=6drYxz2l2JMvKXaZ
At 5:40 you can see a pretty clear image of the full charset which I'm using to
reconstruct the vectors...
I extracted the frames with ffmpeg to png for maximum clarity...
If you want I can post the reconstructed charset once I'm confident it's ok... Or
the images extracted please let me know
