  Aha! So, if I were doing numerical linear algebra in a
uVaxII 
 w/o the optional
 FPU, I could expect performance to be badly hit with respect 
 to the 0.9 VUP
 rating. 
Yes. But although there were part numbers
produced for MicroVAX II CPU modules
*without* the FPU, I don't think *any* were
ever shipped.

  How do I know if my Vaxstation 2000 has the optional
FPU?  What is
 its model number? 
The UV2K tech manual is at
 http://208.190.133.201/decimages/moremanuals.htm
but I'm pretty sure that all 2K systems
shipped with an FPU.

...
  What about the Vaxstation 4000/60? Does it have a
built-in FPU? 
Again it's a separate chip (IIRC) but neyond the
MicroVAX II era, everything shipped with an FPU.
I cannot think of any exceptions.
