Thanks for sharing this! It instantly brings back good memories -- running simple BASIC programs when I was a kid, on a tektronix 4050 workstation my dad brought home from time to time (he worked for tektronix during the eighties). I believe it had something similar to these XY displays. Those smooth lines and distinct glow... you have to see it with your own eyes.
