The 186 was really intended as a controller. It was an 86 instruction

It had a few enhaced functions. Memory mapping saved external
hardware. As I recall, it had a serial port as well. This made it
good for embedded Forths.

What was surprising is that no IBM PC product
ever used the 80186.
I seem to recall something about the use of "reserved" interrupts or similar
that was the reason behind that -- apparently somebody (m$?) used 'em anyhow,
making the '186 not an option.
