(I certainly had no idea how they achieved those line graphics, much neater than on my Apple II, when I first saw the game in 1981.) Managed to fix them both, built a little “picture frame” cabinet with power supplies and buttons for one of them, and have hence been able to play Asteroids on my oscilloscope. Nice, but something was missing…

I think I found a good solution for accelerating the XY driver to keep up with the Asteroids drawing speed; small-signal bandwidth (rather than drive voltage) was the key.
