               pdp11
                    True if you are on a PDP-11/45 or PDP-11/70.

               u3b  True if you are on a 3B20 computer.

               u3b2 True if you are on a 3B2 computer.

               u3b5 True if you are on a 3B5 computer.

         shell procedures [see sh(1)] to increase portability.

         The machid family of commands is obsolescent.  Use uname -p and uname
         -m instead.
