MPLAB and some PIC programmer software have built-in disassemblers.
If you are trying to reverse engineer 16C84 code these are useful but
are not perfect.  A disassembler for the hacker should include a way
of updating the disassembled listing as more information about what
the program does is gained.  An interesting example of such a thing is
Markus Kuhn's PICDIS.  The C source and PC executable can ge grabbed
from:

ftp://ftp.informatik.uni-erlangen.de/pub/multimedia/tv-crypt/microcontroller/pic
 dis12.zip

Just in case the long URL is mangled by your mail reader: Grab
/pub/multimedia/tv-crypt/microcontroller/picdis12.zip from
ftp.informatik.uni-erlangen.de by ftp.  It's been a while since I
looked at this but I think it needs INHX16 hex files if yours is in
INHX8M format use swaphex from:
