 Dr. Dobb's  68040 Programming  July 22, 2001 
  The newest member of the 68000 family, the 68040, essentially combines a beefedup 68030 and the lowlevel functions of the 68881 floatingpoint coprocessor onto the same chip. 
  Motorola's goal appears to be to make the 68040 as suitable as possible for largescale multiprocessing systems. 
  On the 68040, the only floatingpoint operations supported are absolute value, add, branch on condition, compare, decrement and branch conditionally, divide, move, move multiple, multiply, negate, nop, restore internal state, save internal state, set on condition, square root, subtract, trap on condition, and test.
