"Super ResEdit" has a built-in 68k disassembler almost identical to Resorcerer's. It only disassembles though. This is freeware as far as I'm aware and can be found easily with Google. I'm not sure how good of a disassembler it is though.

To use the disassembler on a dump of hex data, create a new 'cdev' resource (for example), open it with the option key held down and then paste in the hex. It will disassemble when opened normally. It won't let you edit in the disassembler though.
