Acknowledgments
This is where I’d like to thank all the people who have helped
me in various ways while building this program:
Thanks to HP for creating such a wonderful and useful
tool. It was a triumph in art, design, and technology. The
first page of this manual is excerpted from the incredible
manual that HP delivered with the original HP-67.
Also, my thanks to all the volunteer testers both for this
new version, and for all the older versions I have done of
this program since it’s first incarnation as a Windows app.
Thanks to my Dad who bought this calculator and allowed
me to play with it when he wasn’t using it. It taught me a
lot about programming!
