Earlier quoted context omitted.
There was a way you could burn out a chip in the C64 with a poke command IIRC. And you could break the tape advance relay in the MSX by switching it on and off rapidly. Edit: Oops it wasn't the 64 but the PET: https://dfarq.homeip.net/the-killer-poke-for-the-commodore-p... Also, everyone here will know the phenomenon of bricking. You can damage hardware with software. Luckily it's very rare.
the tape relay was one of the TRS-80s IIRC. You could toggle it back and forth fast enough to overheat it and get it stuck.
But it was exactly the same thing yeah.. Jiggling the relay super fast would fuse it. One of my friends had this happen to his MSX 1, I think there was some early 'malware' in a copied game or something. But at least a relay replacement is not difficult or expensive.
