It was introduced in and is the first calculator that is capable of symbolic computation.

HP series – Wikipedia

For example, you can use it to solve quadratic equation symbolically. And, it is also one of the first graphing calculator.

This is a RPN calculator, and manaul also a programable calculator. The first graphing calculator is Casio fxG It is actually the HPs that i did my first programing. I never took any programing course, but am a avid learner of math and computer stuff. I read the manuals from cover to cover.

My first program is a program to solve the Eight queens puzzle. It was a puzzle posted to CompuServe ‘s math forum. At the time, i’m also a crazy fan of recreational math.

I took it upon myself to solve this by programing my super calculator to automatically generate the solution. The 8-queens puzzle is typically solved by a backtracking algorithm.


This is what i did, even though at the time i know nothing about computer science or programing. That is, my program misses 8 solutions or was it 4? Aroundi’m taking music classes. One mahual the things in music theory and training, is to understand the various chords, and being able to identify by ear. The HPs is capable of playing simple beeps of various frequencies.

Thus, i actually wrote jp28s relatively large program that plays musical chords and scales. These programs can spell and play any triad or seventh chords. Enharmonic chords using double sharp or double flat as roots are not generated nor recognized.

Chords starting with other keys are similarly entered. You can also change the ratio between adjacent notes to get 24 note per octave micro turning or other strange h28s.


To do so, simply change the value stored in DUR or R. For more information, see the variable diagrams in Section 3 of this book. This system will be expanded in later version.

The following functions are good candidates for expansion: Readers are welcome to send in their. You can download the full documentation and program here: The file in Microsoft Word format. I’ve written a bunch of other simple programs that help me study math in college.
