But an original PDP/11 is almost as massive......

For the fun of the argument: I was privileged enough to see Carl's IBM 1130,
and to my newbie eye, it may justifiably earn the title of "small" computer,
when compared to its brethren of the time. But it would never occur to me to
call it a mini! It's quite a biggie computer actually. Heavy stuff, forklift or
winch
needed to put it safely in the truck as I recall. Then I thought our IBM 1401 was
big. That's when more knowledgeable people pointed me to the IBM 7090. Now
that's *really* big. And then you have SAGE. Now that's huge. Or insane,
depending on your engineering point of view :-).

I strongly suspect it was around the time that
the PDP11/20 came out or
slightly later.
The IBM 1130 and 1800 were comparable to the
/original/ CDC 1700, were
similarly launched in the mid 60s, but similarly they were not /at that time/
referred to as minis.
In retrospect we might well call these minicomputers but that is not the
question
as stated.
