The Museum of HP Calculators

MoHPC Software Library

This library contains copyrighted programs that are used here by permission. These programs are grouped by the calculator for which they are written but it is fairly easy to port a program from one RPN calculator to another.

Additional programs and manuals are available on the Museum CD ROM. Additional programs may also be found in the HP-41C Software Library, the HP-95C Software Library and the Articles Forum. Additional HP-41, HP-71 and HP-75 files in LIF format (and LIF Utilities) may found at the Museum FTP site.
