80186 was made for embedded markets and had features deemed incompatible with
IBM PCs. Having said that, it was used in quite a number of PC like devices. See

The 80186 wasn't interesting enough for people to make new boards. It wasn't
pin-for-pin compatible with the 8086; it had on-chip controllers that had to be
wired up separately for the 8086.
There were a few machines that used it, but it never went mainstream--it was
only a bit faster than the 8086 clock-for-clock, but it had the same address
space limits. "Interesting enough" didn't happen until the 80286 with
protected mode. (The 80286 got to star in the IBM PC AT... where they stuck
with it while everyone else found out about the 80386.)
The government-mandated CEMCORP ICON was one; a classic example of the Ontario
government designing contract requirements that only a local company can
fulfill. (That way, it's not a bail-out or diversion of funds! It's just
responsible business!) CEMCORP got bought by Burroughs, who got bought by
Unisys, so by the end we had quite a collection of company logos on the various
nodes.
Say, remember protected mode was an 80286 feature? The ICON ran QNX, a
UNIX-like system. And the 80186 does not have protected mode.... Fun with
finding root passwords was had....
