And the Z80 had a 4 bit ALU. Note that the 68000 actually had three 16 bit ALUs and could crunch 48 bits per cycle, depending on what operations you were doing

And the Z80 had a 4 bit ALU. Note that the 68000 actually had three 16 bit ALUs and could crunch 48 bits per cycle, depending on what operations you were doing since one was a full ALU while the other two more simple adders/subtractors.
