Fair enough: sounds like your definition of "hardware architecture" is limited to the processor itself.

If you're curious about the Newton processor: http://www.ot1.com/arm/armchap1.html (see the "ARM6" section).

Well, processor and memory (I certainly think NUMA machines are different), everything else is pretty much just I/O.

Thanks for the link.
