The purpose of this web site is to provide basic operational information about a few modules for the Hewlett Packard Series 41 calculators. The selection is mainly made on my own needs. However, I will also listen to your wishes. Hopefully the information available here will grow over time.
Your feedback is welcome. Send me your comments or suggestions using the feedback form of my calculator blog. Of course, you may also contribute to this web site: if you want to see a particular quick reference guide here, let me know. Maybe you have even scanned images. Any help is highly appreciated!
