Just random RT OS's? It's been awhile since I've worked on tiny 8 bit mcus, but all the stuff was really small and seemingly hand rolled, nothing as monolithic as Linux.

I would not be surprised to learn that it varies from company to company and chip to chip, with various bits being shared for common logic.

I remember VxWorks. Bigger than a while loop, but used in space missions back in the 90s: http://www.windriver.com/inspace/

Edit: looks like VxWorks wants a 32-bit CPU, 128KB of ROM, and 1-2MB of RAM. But you get threads, networking, filesystem, etc.
