But geostationary communications satellites did. Nothing wrong with the hardware, it had been programmed to be a serial murderer under certain conditions. Deliberate, not even a bug and of course contrary to the laws of robotics. Somewhat like HAL, sadly my father has dementia and likes reciting nursery rhymes (and gets them wrong), which gets under the skin of the other residents of his nursing home and he had a fight with an old lady who broke his glasses and he hit her with his walking stick. The staff took the stick away and later we got a call to say he had had a fall, hardly surprising. Gone slightly off topic there a bit, sorry. Does anyone here have a use for a BROKEN wide format Hewlett Packard ink jet printer? I think we got it in 2000, so not ten years old quite yet but useful for printing schematics if you have the knowledge/patience to repair it. It might even be a current model, things move slowly in the wide format side of things where low volumes force design costs to be recouped over longer periods.
