@bobjonkman Ha! Well, we were on near faulty ones over the weekend. The Hotel Pennsylvania is quite old. I think its held together with layers of paint. (I waited till I was home to open your link.)
It was a ~14" LCD mounted above the buttons in the elevator. It would show a TV news channel while the car was in motion. As well as display the floor. When it would crash it rebooted windows. I don't think it was actually running the elevator system. It was still funny though.
This is happening quite a lot in my line of work, for quite a while now. Large old, rat trap relay, resistor bank, x-former, type cabinets get stripped out and a little PLC get installed.
