  3.                    TP 6.0 Turbo Pascal Library
  4.                               versus
  5.                 TP 6.0 Runtime Library Update 1.7
  6.  
  7.  
  8. Note: The time resolution in the ARITEST test program is about 0.3
  9.       usec, so the relative timing error can get quite large for
  10.       small times like those measured on a 486. For the 486 values
  11.       below, the average of three measurements were used for the
  12.       comparison.
