While it isn't all that common, some places have lousy line voltages, which can cause problems. I ran into this myself in the C= lab during the A2620 development. I had the A2620 to the point where it would run for a day or so, then lock up. The A2000 it was plugging into, on the other hand, would go virtually forever without a lock up. So I spent over a week trying to catch some "almost never happens" kind of logic glitch. Then one morning, while I was looking for a condition that was never supposed to happen, my analyzer triggered and the monitor display jumped. The analyzer showed every signal in the system glitching for just long enough to throw the A2620 into limbo. The faster you go, the smaller a fatal glitch can be and still cause you trouble. And this lab bench AC supply was glitching just enough to crash the faster A2620, but practically never enough to affect a plain A2000. While supplies are designed with the idea that the line supply is never quite what you would want in a computer AC line, they can't handle everything. If you find that a computer is real flakey one place, but works great in a different place, you may have some kind of power line problem. Sometimes the power company has nothing to do with it -- turning on heavy equipment, the same kind of thing that dims your lights for a second or two, may annoy your computer as well. >From the desk of Sean Reifschneider.
