There have been several requests for a program to check for the
presence of the floating point processor, and to see it in action. 
This little program is quite unscientific, has no basis in fact, and
was written quickly, just to see what happen.
	The first thing that the does is check to see the presence of the
MC68882 co-processor.  Then it does three sets of floating point
operations, either 1000 times, or 10,000 times.  The first operation is
the addition of two numbers, the section is their multiplication, and
the last is the calculation of the sin of 2.3.
	The numbers that are observed are counts of the 200HZ timer.  The
results that I get on my TT are:

                              1000         10000
Addition     With               4            55
             Without            8            84

Multiply     With               3            28
             Without           10           104

Sine         With               5            47
             Without           89           891

   Thus it is about 60% faster for addition, 300% faster for
multiplication, and 2000% faster for the trig functions.  Try your
machine and tell me how it works.
