You want to talk trap patches? Your Mac's INITs have minimal trap patches, touch the Toolbox in boring places like SysBeep() and GetNextEvent(). The Developator's Mac has big, tricky INITs with trap patches that hook into half of the Device Manager.[1] The Developator is in touch with the metal, starts like a warm boot off the ROM reset vector, stops on an NMI.
