 *  TEST.C - a Quick 'n Dirty program to demonstrate use of the 
 *             function, chips(), which identifies CPU and NDP 
 *             (math coprocessor) type at runtime..... 
 * 
 *             Make sure you load the project file TEST.PRJ and 
 *             that your are compiling under the Small, Tiny or 
 *             Compact memory models.
