Apple didn't revolutionize power supplies; new transistors did. Lisa, Macintosh, and Mac 128K through Classic. I could not find any non-Apple power supplies that use this mechanism, except for a 1978 TV power supply, and it. Marvelous piece of work, with insightful and helpful comments by a number of posters.
