    MacOS 9 is the accumulation of about 20 years of proprietary code for the Motorola 680x0 and Apple/IBM/Motorola PPC families of processors. The source code is various parts 680x0 assembly language and C++. MacOS X is the accumulation of about 15 years of Mach-based BSD development beginning with NeXTstep in the late 1980's. Of course, BSD traces its roots to UNIX, which dates back to the mid-70's. The closest you can get to MacOS X is the opensource OpenSTEP clone, GNUstep.

    This bit of advice: As practice for acquiring the source code for MacOS and MacOS X, take a trip to Atlanta, GA. Visit Coca-Cola headquarters and ask for the formula for Coca-Cola.

    but anyways apple will not disclose the os 9 (or any classic os) source code. Using a disassembler is the closest thing to it (although that is illegal).

    No source, but there is ample sample code.

    OS X device driver help should be here...

    If you want to write a OS 9 driver that'll work under OS X's classic you'll need to look at Carbon...

    Edit -- Don't remember where they were talking about converting driver to work under classic, may need to search.

    Booting into OS 9 will allow you direct access to hardware for a driver, but will not work under OS X's hardware abstraction layer and should be in the Legacy Technologies in the above links.

    Edit -- Getting Getting Started With Device Drivers
