      I've read a lot of news articles this week about Apple adopting ARM processors for future Macs, but not one of them seemed to mention that ARM was created as a joint venture between Apple, Acorn and VLSI in 1990.

      Baby 👶 is coming back home 🏡 🍎❤️ I wonder if any of the original designers are still at Apple?

      The original designers (primarily Sophie Wilson and Steve Furber) were never at Apple. It was entirely Acorn's design, and Apple just helped to fund it as a spin-off so they could use the chips in the Newton.

      Ah, I remember the Newton, my uncle had one! Why do I have some recollection there was some chip design discussion about synchronous vs asynchronous processor architecture?

      I don't really know what that would mean... but there was plenty of "discussion" about CISC vs RISC architectures...

          PowerPC was part of that debate, but some smarter folks started to understand it’s power efficiency that’s important. That kind of validated the entire ARM existence and Intel’s plan B with the Core micro architecture gave them air to breathe (while PowerPC imploded on itself).

          (Not saying ARM is asynchronous, just saying it brought back some memories).
