The three DWG files provided here are AutoCAD drawing template files 
designed to facilitate making P.C Boards for three popular computers.

They are Apple.dwg for the apple II boards,
         pcxt.dwg for the popular IBM's and clones, and
         stdbus.dwg for the system building block boards.

To use them just start AutoCAD and select option 2 for new drawing.
Give the name of your board followed by an = sign and then the name of
the template file. Ex:

             ACAD
             2
             myboard=pcxt

The templates have been set up with the folowing layers for the different
portions of your board:

            Component     for component side traces and pads
            Solder        for solder side traces and pads
            Silk          for silk screen info and part outlines
            Drill         drill plan information - hole centers
            Mask          for making solder mask patterns
            Edges         for detailing board outline edges
            0             for all common information.
