 *  Excimer board demo program running on DINK32 software.  There
 *  are 3 files associated with this demo programs:  demo.c, demo.h, 
 *  and makedemo.  makedemo is the make file, it defines the entry
 *  entry point of the program.  Currently the entry point is 0x70000.
 *  To build the S-record file demo.src, type "make -f makedemo".  
 *  Whence this is done, download the demo.src file to the board using 
 *  the "dl -k" command, then execute the demo program with the 
 *  "go 70000" command.
