') Home yolaindex -This website contains several programs that I've written for this wonderful pocket-calculator: the HP-41C/CV/CX -Some of these programs are very slow on a real HP-41, so it's sometimes better to use them on a good emulator like V41 - written by Warren Furlow. See www.hp41.org -You can convert the text files to raw files with http://www.hpmuseum.org/software/hp41uc.zip -The HP41-memory may be increased a lot with the modules built by Diego Diaz like NoV-64. See www.clonix41.org -Another alternative is the new fantastic 41CL created by Monte Dalrymple. Cf www.systemyde.com/hp41/ -Most of these programs will also run on an HP-42s -And with the excellent free42 , they will run more than 5000 times faster ! -The WP34s created by Paul Dale, Walter Bonin and Marcus von Cube may also be used with minor modifications of the HP41 programs. -Though not so fast as free42, it is much faster than the HP41. -And it is certainly the most powerful purely RPN calculator. -I hope that these routines will be useful ... -If you want to learn the HP-41 programming language, I strongly recommend the 3 excellent books: [1] Philippe Descamps & Jean-Jacques Dhenin
