Introduction
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.
Recently, I added quick reference information for the HP-9872 plotter. Of course, this is not a module for the HP-41, but convenient for myself to have it here as I own such a plotter and play around with it as time allows. The next logical step would be to add some information about the HP-7470A plotter. Let's see if I find the time to do so.
