Chap blew up critical equipment on his first day – but it wasn't his volt

Similar experiece

I did something similar with a manky old Oscilloscope years ago. Think it was a Hameg thing. It'd come back from site abroad where it was run on 120V and never returned to 240 back in our labs and when I plugged it in it went pop. I was never allowed to forget this but the bastard I worked for did the same thing about a year later. Obviously I couldn't say a thing but it became one of those elephants. Great fun..not.

Hardware duplication

I ended up supporting some very specialised equipment a couple of years ago that was based on hardware logic. It dated back from probably before PLCs were thought of. The documentation was very poor and incomplete and inaccurate. All based on CMOS 4000 logic and various obsolete analogue multipliers etc. Nightmare.
