Beautiful! What are you using to generate this image?
I'm using an AdaFruit ItsyBitsy M4 Express with its two analog outputs
to drive the X and Y inputs. The text is being generated using the old
Hershey vector font.
I dont see a connection to the Z-axis (or did you use connections from
the back-side of the case ?) so I'm surprised to see such a crisp text
display. I was planning to turn my USM-117 into a scope-clock, but I
found a decent kit online last year. Even though I have an HP digital
scope, I still like bringing out this oldie for every now and then for
bench work.
For visible segments, I draw slowly, for others, I move quickly, so
I'm not using the Z input.
Ah nice, I am working on an X/Y/Z driver that could be used for CRT
clock purposes. Rather than direct X/Y drive, it uses integrators for
analog lines.
Some of the specs are here:

And some pics from yesterday:

It does text, but this isn't shown here.
If anyone is interested in a PCB, contact me privately I guess!
