SPECmark89
     
         An old {SPECmark} {benchmark} result derived from
        a set of {floating-point} and integer {benchmark}s.  It is the
        {geometric mean} of ten {SPEC ratio}s of the outdated 1989
        {SPEC} benchmark suite.  The use of SPECmark89 is strongly
        discouraged, having been superseded by {CINT92} and {CFP92}.
