Our friend Ron Seybold was wrong on one little detail.
He said:

Sorry, Ron, they DID ship a few 930's.  I know, because
I ordered and installed and was system manager for one
here at NUWC Division Keyport in 1987.  I believe Keyport
and Boeing got the first two then-MPE/XL boxes in the
Pacific Northwest (think they had a 950).  But you are
close to being right:  Only a few 930's actually got out to
customer sites; maybe ~ 100.

....  And of course they didn't last long:  Not too far into
1988, our HP sales rep (yes, we actually had a real, live,
local sales rep back then) asked us if we wanted to
upgrade our 930 to a 950;  they were offering a real good
deal....  We said "No thank you;  the 930 does what we
need for now".....  After which they proceeded to give us
a brand new 935 at no cost...      ;-)

I still have that good ol' 935 in one of the short roll-around
cabinets...  We used to run up to 80 users on it.  It works
pretty well as a small end table...  Enough of making
myself feel old for today...
