Everything else being equal, a machine with a more orthogonal 
structure  -- many op codes can be used with addressing modes
and many registers  --  should produce larger programs.  Thus the
68000 family machines, being more orthogonal than those in the
8086 family, should produce larger code, as shown by your data.
