Real-time, pre-emptive multitasking, embedded.
Comes with source-code, have to buy the book to be legal.
Heck it even has a TCP/IP module.
Quote (page 72) of the said book:
"A minimal kernel for an 8-bit CPU that provides only scheduling,
context switching, semaphore management, delays and timeouts should
require about 1 to 3kB or code space."
So theoretically it'd be possible to port this to a 16kW PDP.
