This week I'm finally retiring my oldest computer, a Power Computing PowerWave circa 1996. It lasted seven years because virtually everything inside it that mattered could be upgraded. 1996 was the nadir of Apple manufacturing, and Power Computing was a breath of fresh air. For a few years, all of the most exciting MacOS-based systems were Power systems. They were built with the user in mind too -- everything could be upgraded. Slots and ports were abundant. (Who else had eight DIMM slots in 1996?) Compared to the Power Computing machines, Apples were under-powered and over-priced. So it wasn't really a surprise that one of Steve Jobs first acts when he took over at Apple again was to pull Power's license. Too bad. They made great machines. I'll miss mine.
