Mystery system

[Mike Loewen]

    I'm trying to identify a system which appeared in "The Killer Elite" 
(1975), with a room full of tape drives and a couple of terminals:

    The drives appear to be IBM 3420s, but with an additional box on top, 
labeled "SMS".  The system itself doesn't appear in any of the shots. 
Some sort of IBM 370, perhaps?
