My previous quote was taken from the "VAX Architecture Reference Manual",
Copyright 1987 by DEC. Page 359.  I cannot find any reference to any
"MicroVAX architecture" in that edition of the RM.  Instead they talk 
about subsets of the VAX architecture.  

There is clearly some inconsistency in DEC's terminology here.  It would
be interesting to see if later editions of the MicroVAX Handbook say
the same thing as the 1984 edition.
