Will need to degauss after this
What, you don't need the data any more? Or are you conflating screen degaussing?
We used to degauss the CRTs because it looked cool and there was nothing else to do. Very adjacent to watching the defrag window maximised.
I did it in computer lab and showed others and the teacher lost it, thought we were breaking things.
It also made a really satisfying “boyoyoyinnng” sound
