Maurice Re: "glimmerings" Maybe that is what it is, or maybe it is just the result of the efforts of the large numbers of brainy programmers that GOOG claims to employ, sitting there with great piles of books of all sorts and every single edition of Britannica and many other similar works available for reference. <g> That Belgian industrial estate is what I would have enjoyed. You know though, most of that automation you were observing there was likely relay logic, scads of gold-flashed and silver contacts rather than anything based on silicon. For sure back in 1987 or even now for many applications. You can build some pretty elaborate systems with relay logic, though. For mission-critical stuff, where you must interlock to prevent a dangerous chain of events you just have to use hard contacts. One single misgated PNP junction could cause a disaster. Also, with anything solid state there is always the lack of certainty in the power-down state, not something you want with a steam boiler, especially a nuclear one. You may use computers for math functions like proportional control, but the real boss of the system will be a relay array of some sort. Slagle
