Read This Evaluation License Carefully.

This is a legal contract between the person who downloads (you), and John W. McKown (John).  Within the United States, its territories and possessions a license is required in order to build,  sell, or use anything covered by a valid US patent.  This includes building prototypes for evaluation.  US patent number 6,429,854, which is in force, covers the keyboards disclosed on this website and in the downloadable files available here.  John is the owner of patent no. 6,429,854 and exclusively retains all rights inherent in that ownership.
John hereby grants you personally a free, nontransferrable license to build and use, for experimentation and evaluation only and entirely your own risk,  not more than 5 simultaneously intact keyboards covered by US patent no. 6,429,854.  These keyboards shall not be supplied to 3rd parties for long term use.  If you want to build a sixth keyboard you must destroy one of the five existing ones.

The downloaded software is provided "as is" and the accompanying information on prototype construction is for evaluation only.  Any express or implied warranties, including, but not limited to, the implied warranties of merchantability and fitness for a particular purpose are disclaimed.

In no event shall John be liable for any direct, indirect, incidental, special, exemplary or consequential damages (including, but not limited to, procurement of substitute goods or services; loss of use, data or profits; or business interruption) however caused and on any theory of liability, whether in contract, strict liability, or tort (including negligence or otherwise) arising in any way out of the use of this software or the use or construction of  the keyboards, even if advised of the possibility of such damage.  

This is not a license to sell or manufacture.
