HELP! Need advice/program to convert object files -> assem

[Chandra Bajpai]

We have some .o (C Object files) on a SUN-3/80 that we need to
recreate the source from.  The problem is that the programmer who
wrote the program left a while ago and we cannot find the source.
I need some advice on how recreate the source code into either
assembly 68K or preferably C.  What are the best tools to use?
A worst case I could write a object module diassembler if I knew
what the format of a .o file is.

Thanks for any help you can offer.

Thanks,
