     My friend bought a 486-25.  He said he did not order the 
co-processor (something like Weitek co-processor).  I know that 486
has the feature of built in math co-processor.  But what is 
this co-processor for?  Why is there another co-processor appeared 
after Intel integrated the math co with cpu?  My friend could not
explain the function of this "Weitek" co-processor.  Can any one
out there tell me what this co-processor is and why?

     Thanks in advance.
