The following commands will return a true value (exit code of 0) if you are on a processor that the command name indicates.
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. u3b15 True if you are on a 3B15 computer.
