RPL runtime for the DM42 calculator, in the spirit of HP48/49/50

Forth for Swissmicros DM42 calculator

Convert state between clones (SwissMicros, JRPN) of HP’s Voyager calculator series (HP-15C, HP-16C) from the 1980s

Demystifies and prints memory contents from the SwissMicros DM41 calculator's text dumps

A kind of User Manual repository for SwissMicros devices

Astrodynamics32 is a DM32 statefile for circular-orbit calculations. It takes one known orbital parameter (height, velocity, period, sidereal days, or circumference) and computes the remaining values using stored Solar System constants. Designed for quick, self-contained orbital mechanics work directly on the calculator.

Comprehensive date calculation capabilities for the SwissMicros DM32 calculator, replicating and extending the date functions found on the classic HP-12C financial calculator. The programs enable date arithmetic, day-of-week determination, and liturgical calendar calculations.
