There was some things in the early days which effectively were 2 cpus running the same program. If the 2 didn't agree, one was obviously faulty. I never met one outside space or military work, which I refused.

If the 2 cpus disagreed, the cpu was faulty, so it doesn't get to launch any nukes

They didn't know which one was dud, but overheated wafers expand so neither could be trusted.

This was a brain dead idea that lasted a year or so. Because once they started thinking about EMPs ……
