Presumably OS/VS2 Release 3, the second release of MVS. The MVS releases of
OS/VS2 ran from 2.0 to 3.8, with a bunch of optional selectable units ("By the
pricking of my thumb, SU 7 this way comes.")

Hi Leonard,
You said: "... That computer center had MVS 3.0 running in the mid
1970s. ..."
Is "MVS 3.0" a typo? (I do not recall ever hearing of MVS 3.0.)
Thanks and regards,
David
