I want to bring up Macsbug while Mac OS 9 is booting. I tried command-powerkey (real left and right command keys) but that didn't work. Command-fn-f12 also didn't work for me. Anybody have any luck with this when using a Mac OS X host?
I haven't tried but a web search suggests either Command-Eject could work or Ctrl at happy mac display. See: http://davespicks.com/writing/programming/mackeys.html
Or if these don't work but you can compile programs for MacOS 9 you could make an executable that tries to execute an illegal instruction so starting this executable would bring up the debugger.
