Neither were the VAX-11/725, the VAX-11/730, The VAX-11/750 nor the 
VAX-11/780!

The newer VAXen were, indeed, faster but getting great speed from a CISC 
architecture is neither easy nor cheap.  A RISC design plus an 
optimizing compiler will almost always beat CISC!

I have a VAXStation 4000/VLC and a MicroVAX 3100.  It has been years 
since I booted either one.  My Alphas will run rings around them and do 
just about anything a VAX could.
