Yes that does seem to be true. Was the 80186 actually

Do you mean like development systems? I'm
not
aware
of any pre-AT '286's - not saying there
weren't
any.
They seem to have less exposure then pre-5150
Intel
stuph.
Definitely were. I worked on the port for the
Durango Poppy, for
example, using early steppings of the 80286.
Interesting thing is
that pre-production silicon was available on the 286
and the 186 at
about the same time. I wonder if there were any 80286 coprocessor plug-in
boards for the
XT before the AT?
I'm guessing so, w/o specific knowledge. One of the
first though was the Orchid Turbo-186, but was
revamped with a '286 before very long. There were
patents assigned to the original board:

funny, Google's cached deposits are as slow as the
original server's.
Here's a neato question: You mentioned coprocessor
boards, and in fact some kinda sorta functioned that
way (in some sense - stuff got offloaded to the mpu on
the board I guess). But what were some early ancillary
processor boards for the pc/at/?. That is, where you
plugged a whole 'nother puter into your main puter,
and got to run separate apps off of that? Hmmmmm
