All I can say is that it worked in several other contemporaneous

The Univac 1108 and followons is another.  There may be others, perhaps
the some of CDC systems as they and the Univac systems shared a common
designer (Seymour Cray).

While Seymour Cray worked on the 1103, he was off to CDC long before the
1108 was designed. I don't think the idea of multiprogramming and
swapping (and hence the need for a base/limit register pair) had entered
anyone's mind back in the days of the 1103.
