Description

This project has created scientific firmware for the HP-20b and HP-30b business calculators.

The WP 34S turns either of these business calculators into a powerful keystroke programmable scientific device.

The WP 34S has been alive and stable since 2011. We have succeeded in satisfying the most picky users - read about their experiences on the http://www.hpmuseum.org/forum.

In 2014, we've updated the WP 34S to version 3.3. The documentation for the WP 34S is excellent and comprehensive (see customer feedback); a print version is available from: https://www.createspace.com/5304580

We have also produced produced the WP 31S which is derived from the WP 34S source code. This is an entry-level scientific calculator. The printed manual for this calculator is available from: https://www.createspace.com/4773370

    Absolutely magnificent good work. A perfect calculator project. A briliant idea as well, to replace a half stupid hardware with a big brain transplantation. In this project I can smell the engineering art of HP in the late 70th to 80th. Delivered with a professional documentation, which seems to have the approach to be comprehensive, which is quite impossible in view of the wealth of functionality. And as far as I tried until now, there is no error, no single bug in the software!
