If I remember correctly, NuBus ROMs start at the _end_ of the slot's 
address space and work their way back. If you look at Apple's old OS 9 
tools, there was a tool that helps you examine the SlotManager 
information on cards graphically. This will give you addresses and then 
you can take a look at those addresses in macsbug, or my favorite: dump 
the code to a file, open it in a hex editor, copy and paste to ResEdit 
CODE editor, and enjoy symbolic assembly dumps.
