rejig for Windows (x64) 0.39.0   (details) Other ENG   3,061 KB
Ever found an RPN calculator program online you wanted to run, but it was in the wrong file format for the machine in front of you? Ever wanted to export a working, battle-tested program to another RPN machine family? rejig raises every input you give it to an abstract version of the R47 program format, serving as a high-level lingua franca, then writes it out without changing its semantic meaning. Supports UTF-8 text, R47 byte code, Free42/Plus42/DM42/HP-42S/41C, HP-35s/32SII/DM32, HP-11C/15C/16C, and more. Executable for 64-bit (x86-64) Windows.

voyem for Windows (x64) 0.2.1   (details) Other ENG   4,912 KB
Command line-only HP 12c (2015+) / HP 15c CE / HP 16c CE firmware emulator meant for testing behavior in automated workflows such as hypothesis-testing in LLM based coding agents. When run in this manner, it is pure in a mathematical sense: starting from a freshly reset calculator state, it loads your test program in, runs it, and then reports the resulting calculator state. One used to dealing with functional purity on desktop computers might view the changed contents of RAM and the LCD as “side effects,” but in this context, they are part of the program’s output, available for inspection inside that same hypothesis testing loop. Executable for 64-bit (x86-64) Windows.
