Setup 95xxx Tablet with AutoCAD 13 for DOS xxx

1.   Start AutoCAD and type "CONFIG" at the Command Line.

     2.   Choose "Configure Digitizer".

     3.   Do you want to select a different one? [Y]

     4.   Select "CalComp Digitizer Series ADI 4.2 - by CalComp" from the AutoCAD Digitizer Configuration menu.

     5.  You will be prompted for a model: choose 9500 Series; indicate the size of your board, number of buttons on
          your cursor,  the COM in which the board is plugged. It will  ask if you wish to choose Polling or Interrupt. If you
          have a 486/66 or Pentium system, choose Polling. With the 386 it will depend on the system.  Try both polling
          and interrupt to define which works best with your system.

     6.   Type "0" to Exit

     7.   Keep configuration changes.  [Y]

     8.   Enter the drawing editor by opening or creating a drawing.

        a.  With the polling option, there could be possible crosshairs snagging or sticking  in Autocad.  This would  be a
            fraction of a second delay and happen about every 20 seconds.   Changing the Vscan  rate easily resolves this
            situation.  To make the changes you will need to be in the ACADR13\DOS  DIRECTORY and type:

            CFIG386  ACAD   -VSCAN   XXXXXX. 

            The formula to calculate the "XXXXXX" rate is as
            follows:

            Pentium 200:    20000   x Memory  x 11  
            Pentium 166:    20000   x Memory  x 10
            Pentium 150:   20000   x Memory  x 9
            Pentium 133:    20000   x Memory  x 8
            Pentium 120:    20000   x Memory  x 7
            Pentium 100:    20000   x Memory  x 6
            Pentium 90:     20000   x Memory  x 5
            Pentium 66:     20000   x Memory  x 4
            Pentium 60:     20000   x Memory  x 4
            486:                20000   x Memory x   3
            386:                20000   x Memory x   2
