  Well, you might try moseying down to your local tech. book store and 
picking up a copy of _Operating System Design (Vol I) The XINU Approach_
(There's a PC version and a general version [PDP-11]). It includes the 
sources for the reader to thoroughly explore the OS and type it in as
he/she goes. I just finished the main portion of it (now for the fun part
of debugging it [wow!]); I'm not sure when I'll finish that, if at all.
For $80 you can purchase sources, executables, and example programs on disk.
  For a little extra, you might even consider MINIX, or Coherent UNIX (no
sources) if you really want to play...
