An 80186 is downward compatible with the 8086; it has a few extra
"High-level" instructions (Enter, Leave for stack linkage).

More important, it also has 2 dma channels, 3 timers, programmable
chip-select, and a local bus controller -- ALL on-chip!  (I may have
left something out...).  A pretty nice part if you can stomach the
8080-derived programming model that Intel is committed to.

There was an article in BYTE (May, I think) describing it.  You can
write Intel, too.
