I pulled the 2011 version off archive.org (at https://web.archive.org/web/20110826073121/http://robertpriddy.com/Nos/Nor1.html https://web.archive.org/web/20110826073121/http://robertprid... ) and did an HTML diff with the current version. I put the result at http://dalkescientific.com/Nor1.diff.html http://dalkescientific.com/Nor1.diff.html . I'll delete it at some point. It was the first HTML tool I tried. You may have better results with another tool.
