  A farmer, a hunter, a soldier, a reporter, even a 
  philosopher, may be daunted;
  but nothing can deter a poet,
  for he is actuated by pure love                  HDT

28 Jan 90 converted beep task code to spinTask
 1 Mar 90 Finished working example of SpinPointer
 9 Jun 90 Finally got past linking error
10 Jul 90 Changed Pointer Hot Spot and used #defines in structure
