There were a few 186 (and maybe even 188) machines out there,  but what
happened was that early on it became *imperative* that the 8088-based stuff
be "pc-compatible".  There were a few machines that weren't,  and
they disappeared in short order.

Unfortunately,  IBM in the design of that machine chose to use some
interrupts that intel had called "reserved",  which came into
play with the 186/188 chips,  that's why those were never used all that
much.

The boards that did sell were for people who wanted a more powerful
machine, and didn't care too much about pc compatibility,  not a very
significant portion of the total market.
