Right, forgot about them.  Univac was a big contributor to OS/<number>;
in addition to 3, 4, and 7 above, they also had OS-100 and OS-500 for
variations of their 9300 operating system that hung a Unicscope 100 or a
DCT-500 terminal onto the machine.  These were seldom used - we didn't
need much help filling out the 32K of memory available to us.

c1792 on the Modular One computer:
 
 
OS6
 
  An Operating Systems for a small computing system
 
  Joseph Stoy and Christopher Strachey
 
       ABSTRACT
       Part I is a general description of a simple operatirg
  system, which runs  in a virtual machine (implemented on    a real
  machine by an interpreter).      OS6 copes with only one user at a
  time, and is not a multiprogramming system:  many major problews
  associated with large operating systems  have therefore been avoided
  or considerably simplified.    It nevertheless has several features of
  interest,  including the fact that it is written almost entirely in
  the high-level language BCPL.      The most important single  feature,
  however, is the hierarchical nature of its control    structure, which
  avoids the need for a special job-control language.
 
       Part II covers the facilities for input/output, and the
  handling of files on the disc.      The input/output system uses a
  very general form of stream; the filing system is designed to have a
  clear and logical structure.

Be warned that there are two parts to that publication. Oxford only
digitised one part until I advised them. Even now, the link to the other
part isn't clear.

I have both parts in my possession (both physical and digital). and a PDF
of the related paper.
