For the vintage computer enthusiasts: vid of booting a PDP-11 from tape drive

For some time, the academic supercomputers I know about have been massively parallel, and I don't know if the individual nodes are particularly interesting from a history or hobbyist point of view.

Beowulf cluster?

when it comes to disposal security, there's a physical hard drive wiper(electromagnet) and that's about it ... put the hard drive on there, flip a switch, no more hard drive.

Yep we used to do the same. Same with tape media, though when that was end of life, after zapping it, we then sent it to be incinerated. The hardware just ended up in a store room until it was disposed of by whatever means.
