Do you mean, there were CPUs with 2 ISAs, one in-order and one out of order? Which ones, if you can say?

  A modern x86 runs machine code out of order while an older Atom runs it jn order.

    I think we are talking at cross purposes. I assumed that everyone who has followed the discussion so far knew about in order implementations of a single ISA, which they all were, originally.
