You had me puzzled here. I was going to say "The Atlas was the first
machine with VM", so I tried tracking down your reference. I believe
the correct reference is to the paper "One-Level Storage System", by
Kilburn, Edwards, Lanigan and Sumner, Chapter 10 of "Computer
Structures: Principles and Examples", by Siewiorek, Bell and Newell.
This article was published in April 1962, and it refers to the Atlas,
so it looks as if we're in agreement.
