 The

 coprocessor,

 The emulator is much slower than the NPX coprocessor.

 This will result in poor floating-point math performance
 if the emulator must be used.

-There are lots of them, especially on cheap motherboards.  In particular,
-some motherboards do not have the interrupt lines from the NPX to
-the CPU wired properly.  If this is the case, the emulator must be used

 Emulation of the transcendental functions instructions is incorrect.
 Emulation of other instructions is suspect.
