Attached is Brooks Shera’s final source code and hex file. As a  reminder
in all of his released code Brooks requested that any use of his  code be
limited to non-commercial applications.

Users of this code  implicitly agree to the following conditions:

Copyright © 1997-2008, Brooks Shera.  All rights reserved.   This program

of any kind, including any implied warranty of fitness for any  particular

2.  Redistributions in binary form must reproduce the above copyright
notice, this list of conditions and the following disclaimer in  the

This software is provided by the author and contributors  "as is" and
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 the author or  contributors
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,
even if advised of the possibility of such  damage. 
At this time I like to thank Brooks for all the work he  did, his wife 
Karen Stoll for deciding to release HEX and ASM and Bob Leichner  who 
implemented the software commands. Brooks did not have the chance to put  final 
touches in and complete his work, so Richard McCorkle stepped in and made  the 
final changes. For almost a decade Brooks and Richard collaborated on the  
GPSDO, which benefits all of us. Also major recognition has to go to Juerg  
Koegel an other time nut that put our other projects on hold to check every  
iteration. Attached is part of a test that clearly shows the performance of the 
 Alpha filter and AutoN. Limited by attachment size contact me off list for 
 more data. 
The code supports 16C73, 16F73, 16F873A and  16F876A. 
Juerg using the original A&A board with original  components but a 16F876A 
sees 5 E-12 after 12 hours. The data and Hex file is  for 16F876A. Once 
other Hex files have been tested they will be released. Any  one can also do 
their own compellation using the attached ASM file.
