Here is the direct output from the assembler:
------------------
      NSC 16032 MESA ASSEMBLER Version 3.31    9/19/83               PAGE: 1

      1  000000  2E814800                 extw    r0, 0(r1), r2, 7
                 07

You are correct, there is a typo in the manual!  If you require more
assistance, let me know.
