Adam: I was the SVP of Software, immediately preceding Avi Tevanian. I left Apple just before Steve Jobs rejoined (so I worked at Apple between Jobs, so to speak). I helped convince the Apple Board to invest in what became ARM, and introduced Mach to Apple. (https://www.nassi.com). Cofounder Computer History Museum, Adjunct Prof at UC Santa Cruz, Board of TTI/Vanguard (a think tank).
