This site collects my few publications on the joys of RPN calculators, primarily those produced by Hewlett-Packard, plus the many clones and enhanced tributes. Prime among these is my reportage my journey to enlightenment with the R47.

One noteworthy exception is my HP 32S Lite Layout for PCalc, depicted here. The result is nowhere near a proper 32S clone, but it gets me by when my DM32 is not in reach, or in those instances where a software calculator is better.
