Sorry my bad english;
This is my first post in English, now write about my old hp50g source code , this source produces music in the hp50g calculator, I wrote this source code while bored and now share with everyone, see my video
This calculator produces different sounds depending the frequency & duration of the tone, each tone was programed in the source, the calculator play all tones and produces the music, each tone is a line of rpn source, the sintax is “frequency duration beep”, the RPN Language (Reverse Polish Notation) not use semicolon to finalize each instruction.
