To make it clear - the PDP-11 have a very normal MMU with pages.
Semi-normal. It's rather unusual in that it has a paged MMU with page
address granularity different from the page size (64 bytes vs. 8k bytes).
Yes that's true, and can be annoying (fragmentation), but at least it's
optional -- if you want to you can do everything on 8 KB boundaries and
then it's just like any later MMU, except that you'll run out of core in
no time.
