We used 68HC11 for our operating system course and had to write a simple multitasking OS that ran on real hardware. I got to use that OS the next semester to run on a car that needed to follow a track, avoid collisions, and a few other things. Being a microcontroller you got a bunch of things that today need full development boards right on the chip (ADC, RAM, etc).
