I'm not sure that you'll find every thing that you're looking, but if you have'nt read it already you should read "Inside Macintosh: PowerPC System Software".

Writing an entire application in assembler is usually pointless (more often on a RISC chip like the PowerPC). When assembler can be useful is when you have a few small routines that are called a LOT, which you think you can optimize better than the compiler (often possible with some of the PowerPC's neater instructions like rlwimi and cntlzw).

In other words: write a shell to handle user interaction and getting the base address and rowbytes of the screen in C, then you can do everything else in assembler.
