Learning Modules
A series of very informative learning modules have been created by Gene Wright for HP. These modules expand in much greater detail on the features and functionality of the calculator. Each includes many examples, and the modules are divided into common use cases.
Hacking (repurposing) the HP-30b (or HP-20b)
The HP-30b is a new breed of calculator for Hewlett-Packard, and one that reflects a casual “open source” model for HP. A group of HP calculator enthusiasts have begun work on repurposing the HP-20b and HP-30b calculators for other uses, primarily enabled by accessing the JTAG connector on the main circuit board. This is a work in progress, although the group is actively soliciting individuals to help with this effort.
