As an aside, you could also have gotten this data from the source code:

Interesting - what's the provenance of this? Is this a leaked copy of the System source, or a disassembly/decompile?
It's a copy of the Toolbox ROM code for the Quadra 660AV. It's a real leak, not reverse engineered. You can see comments on the code from the early 80s by the original Macintosh team. It was published online (I think on Applefritter or something) about 20 years ago by a former Apple employee who was having some sort of mental breakdown. He believed it contained proof that Apple was complicit in subjecting its employees to MKULTRA mind control and ran underground maglev trains to other dimensions.
