to a good book. I am looking in particular about scheduling
and interprocess communication implementation in OS-9 (or
probably any extensions of OS9.*)

Call Microware and talk to a marketing type. Said person will be happy to send you free a couple of books: one with an overview of OS-9/68000, and one with an overview of OS-9000. (They are rather similar, but then, the OSs
are rather similar.)
There's also a good discussion of scheduling and IPC in Peter Dibble's book *OS-9 Insights*, which is available, but not for free, from Microware.
