It's true that Turing-equivalence is sufficient to allow a computer
with sufficient storage available to do anything.
But we also want that stuff to be fast (under some metric).
However, the term "general-purpose" can have other meanings. The
sense in which I was using it was: a machine that is efficient at
running programs written in all popular programming languages for
the kinds of applications for which computers are normally used.
Thus, the IBM System/360 was general-purpose since it had string
manipulation instructions and decimal arithmetic in addition to
floating-point and binary integer arithmetic.
I think that history shows that those string facilities were, at best,
overkill. None of the RISC machines had any of that and were faster
and at least as general purpose as 360.
Especially the COBOL stuff like EDIT and EDIT-and-MARK.
