A compiler and linker which can output binaries and object files in the format used by mac os 9 and earlier. codewarrior is one such compiler suite, from metrowerks.

Yes. It is described in some apple site i don't have in memory, and has a bunch of value field which are ok, and appended to it a few assembly instructions. > Is there a documentation of the firmware on what traps are available and > what they do?
