Yes, I know. Please review the history of this thread. Dan brought up the old
vector facility ("As I recall, IBM's original implementation of vector
instructions appeared as an optional extension to ESA/390, but these were never
part of the standard architecture defined in the PoO.") and I was commenting on
where it was documented.

That old vector facility no longer exists on any modern mainframe.
There is a new one that is part of z/Architecture (starting with z13)
and doesn't require extra hardware features.
It is FAST!
