apparently

The oscilloscope is connected to PC soundcard and is in X/Y-mode, with right channel connected to X and left to Y input. Z (brightness) input is not used.

It's connected the same way as we've used at parties where the scopes have been setup as 2D sound visualisers. You just play a sound file that is designed to make pictures.

It's possible in theory to do this on an old TV for a bigger picture, but it's hard to know where on the circuit board to feed the signals in unless you have a detailed service manual.
