Of course there's an 80186, and for that matter an 80188, which is
the same chip with an 8 bit external databus. Both were more widely
used in things like X-terminals, laserprinters, etc rather than PCs
(I seem to remember there was something about the IBM PC architecture
that made it difficult to use an 80186, but I will have to check the
details)
Research Machines produced a 80186-based PC called the Nimbus. If there
were compatibility issues they may not have been visible in the
locked-in education market.
