Is this the one from the 90s?
I was at my first proper grown up job - as an accountant no less - I remember reading about this and going to my boss and telling him we HAD to check all the computers! We did engineering, we HAD to check! (There was some formula you could put into excel to check it.)
He told me to knock myself out and go nuts. I checked all our computers (thankfully we were a tiny company) and I found multiple bad processors.
