          ZipTest is a utility that may be used with PC-Zipper to
          determine the optimum speed for your system.  The utility
          calls each parameter procedure, executes a routine, times it,
          and then records the results.  Upon completion, ZipTest checks
          to find which procedure resulted in a negligible increase in
          processor speed.

          Optimum system performance results at the "crest" of the
          curve.  If your system has a math co-processor, ZipTest will
          indicate a lower result than normal and the results may be
          erratic.   Use a command line parameter several increments
          higher.  See the following graph example and recommendations:

          In this example, ZipTest would recommend command line parameter
          "K" for use with PC-Zipper.

          Use of a higher parameter will not significantly increase your
          system speed and might cause errors if you have weak or
          defective memory chips.  If the use of ZipTest results in a
          system error before reaching completion, you probably have at
          least one defective memory chip.  In case of this type of
          error, make note of the maximum speed reached and use
          PC-Zipper with a command line parameter several levels lower.

          ZIP.EXE can be used as a tool to allow use of a computer with
          a defective memory chip until a new chip or chips can be
          purchased.  Use command line parameters X, Y, or Z to acheive
          satisfactory temporary operation.
