That would be very cool, Barry.  I hope you find it sometime.  Maybe if 
you get a chance you can improve upon it and create a disassembler that 
creates comments! :-)

Unfortunately I do not know what became of it, but what it did was trace the program execution path though every possibility at each branch instruction. Sections or code that were never branched to were assumed to be data although you could force the disassembler to read sections as instructions or data overriding the automatic logic. It also analyzed the data sections to see if they were ASCII text or binary, and then inserted fcb or fcc statements as needed.
