Does anybody remember the Millennium Bug? I remember the panic that ensued with that and the thought that many PCs would cease to work.
I certainly do. Our factory was controlled by a big Honeywell mainframe operated by touch screen workstations. There was a big operation which lasted several weeks beforehand to 'ensure' that the Millennium bug wouldn't crash it all out. What amazed me was that I discovered that the whole system was actually run from a standard 3½" hard drive despite all the cabinets full of a myriad of electronic boxes, and the 'Bug' backup consisted of a copy of this that could be swapped if necessary. Needless to say midnight came and went an nothing happened.
