Do the PDP-11 and the LSI-11 have the same instruction set and use the
same opcodes?

Our lab has a Unimation Puma whose VAL II controller is based on the
LSI-11.  Unfortunately all the LSI-11 assembly language manuals seem
to have vanished from the face of the Earth.  My list of phone numbers
is starting to look like an FSM diagram (DEC XYZ Center: "No we don't
know anything about that, but you could try the DEC XYZZY Center.")

However, I was able to find a book which has a list of PDP-11
instructions and opcodes.  Is it safe to assume that these are the
same as for the LSI-11?

If not, does anyone know whether the "LSI-11 Users System Guide" has
what I'm looking for?  (This was the only LSI-11 document the DEC
people knew about, but they had no idea what it contains.)
