According to http://en.wikipedia.org/wiki/Vax#History, the last VAX was
produced 7 years ago. I'm sure there's still more than a few chugging
away in corporate data centers and manufacturing floors, but as an
architecture, it's pretty much a dead parrot.
IEEE floating point is as near to a universal standard as it gets in the
computer world. About the only thing that has it beat for market
penetration and longevity are 2's complement integers and 8-bit bytes.
