Yes, anything that includes a dedicated multiply or
divide instruction as
part of the instruction set; I suspect a lot of the early implementations
fall into the "simple shift-add" that I mentioned due to the lack/cost of
silicon.
(BTW, line lengths of about 75 or so characters are *much* more
friendly to quoting than line lenghts of *exactly* 80 characters.)
I don't think the multiply implementation in the IBM 701 was shift/add
microcode variety. That wouldn't have been very performant for its
intended purpose (scientific computing).
