Unlike the "Oscillofun" song though, the scope signal is not the same as the audio signal.
The other room had the old computers, a monochrome white monitor, perhaps an orange Hercules monitor and also the old green one. In the green monitor the phosphorus took a looong time to fade away. When you turn it off, you can still read the content of the screen for like five seconds.

I started college in 2007, and they handled us newbies in EE analog oscilloscopes for learning, as it does not have the (in)famous auto-scale button.
Working with other engineers, I’m still the one that can handle an oscilloscope the best.
We can derive many parallels in education challenges arising from introduction of new automated functions in tech.

You can get the 2465A operator manual online to see for yourself.

We had a large lab room full of about 30 scopes and signal generators, most of which had flaky controls. No explanation was given beforehand (that any of the students read, at least), and there wasn't time to explain things like how or why the scope shows a stable display of a time-varying waveform.
And because of the behavior of the controls, no explanation was believable.
It was a debacle.
As for phosphor-like digital displays, I wonder how many patents Tektronix has on the concept. Many of them are probably expired by now.
