A small point:

Ed Lee (fortune!lee) says:

	DEC would not build the VAX ( Virtual Address eXtension ) if they can
	sell the pdp-11 as virtual memory system.

The biggest advantage of the VAX over the PDP-11 is the larger address
space you get with the VAX.  Although you could build virtual memory on
the pdp-11, the 64K byte address space is too small anyway.  Of course,
it is more important to implement virtual memory if you have a really
*big* address space.
