I'll update the page to read:
There were a few variants of the i960 architecture that included
an MMU, but virtually all of the i960 devices shipped, such as
X-terminals, printers, and routers, were based on the cheaper
non MMU version.
Which seems to describe the situation more accurately, though
possibly with a surplus of punctuation.
