One of these days, I need to go fix a lot of the info on those pages
that is incorrect or incomplete.

On this Wikipedia page, notes #44 and #45 lead to IBM z/VSE history pages that
may tell you what you want to know.

Each of the IBM pages has a link to the next decade's history page, so you can
start with the 1980's page and proceed to the others in sequence.
I didn't read all the IBM pages closely, but I didn't see VSE/AF jump out. Was
that actually a version?
ECPS:VSE was a hardware feature on the 43xx machines (I know for sure it was on
the 4361, not sure about other models). IIRC it provided microcode assists for
VSE under VM.

Of course I remember the 3310, although I never used one. But your post reminds
me of a question.
Does anybody have a VSE timeline from the original DOS/VSE and ECPS:VSE that
includes all of the packages, e.g., VSE/AF? There's a wike article on VSE and
I'd like to flesh that out, or, better, put someone up to doing so.

The 3090 processor controllers ran VM/370 on 3370 (FBA) disks. I was able to
actually see one of these at a large NYC shop in the 1990's while touring it
with a friend who was the VP of Operations there. The 3270 screen inside the
3090 box had the VM/370 screen logo.
That made my day. I was a VM/VSE guy at the time and really resented the way
that MVS shops looked down on us, as if we were deprived, backwards children.
And you are right, the 3375's were 3370 boxes that emulated CKD on physical FBA
geometry.
Anyone remember 3310's? Smaller FBA brothers of the 3370 DASD, sold with 4331
low-end CPU's for VM/VSE usage. There was a special VSE version created in the
mid 1980's (SSX/VSE) with simplified and largely menu-driven system generation
and maintenance intended for sale with those low-end 4331 systems. The ISV I
worked at then got to play with SSX/VSE to set up our product for menu-driven
installation on one of those systems.

Current (for us 2.1) z/OS HCD still shows 3375 as a valid DASD device type.
IIRC 3375 was emulated CKD on FBA 3370 HDA's. I also think 3375s were used
as the storage for the embedded 43X1's used as processor controllers on 3090s.
