Unfortunately, what you want isn't the r3000 instruction list but,
instead the 3912 instruction list.  While the original r3000
instructions were well-defined, each manufacturer tended to
add or subtract certain instructions in each implementation
(creating the kind of behavior and questions that you're seeing).

So rather than asking for the list, why not just post the disassembly
and the pc of the reserved instruction?
