The rather obscure but still-available VAX series of computers made by
a small Nashua, New Hampshire company (Digital Equipment Corporation)
introduced the EDIV instruction recently, about 1978.  I heard a rumor
that (at least in some early/small VAXen) it was faster to do two
separate instructions than to use EDIV, although I suspect that this
was an artifact of those implementations.

Followups to comp.arch.
