It does not need to be a full fledged OS, but at least have multitasking capabilities (i.e. a scheduler).
Please mention what processor architecture it works on.

This is a survey, so exact capabilities are not really important. Think of this as being a place to look at for possibilities when your next 8-bit embedded project comes up...

I realize that most 8-bit micro do not require an OS, but just as a counter-example, Rabbit Semiconductor offers the RCM3710 processor module with 4 serial ports, a 10-BaseT ethernet port, 512K RAM and 512K Flash. All that for $39. All based around an 8-bit Z80 core.

8-bit does NOT necessarily mean extreme resource constraint.
