MVS/SE R1 ("SE1") installed on top of OS/VS2 R3.7 and MVS/SE R2 ("SE2")
installed on top of OS/VS2 R3.8; in both cases one of the prerequisite
selectable units disabled DSS ("By the pricking of my thumbs, SU7 this way
comes.")
MVS/SP V1 replaced SE2 and exploited, but did not require, various features.
And, yes, it did support 26-bit real addresses. I saw it on a 4341, but it ran
on anything that had a DAT box, enough memory and an S/370 mode.

Interesting. I remember MVS/SE[1] and MVS/SE2 -- vaguely, before
MVS/SP1.
I remember macros and fiche mentioning 3033MP and I thought it
was 32MB support since each side had 16MB. And I think it was
only the NUC that had that support built into it. The early bar
as it were. ;-)
And then came MVS/SP2 (aka XA).
