Source code (only) of an interrupt-driven digital clock with big numbers. Meant to be an example of how to make use of calculator system clock activation interrupt. It enables low power consumption between screen updates. Program is small, because it does not contain IRQ handlers itself and does not mess with system time counters.
Thirty-one useful tools written in System RPL and assembly language, including Euler's numbers, the gamma function, a variable hider, a routine to recall the system libraries, and much more.
Program for extracting/displaying contents of HP 48/49/50 directory objects on your PC. Written in GNU C. Includes source code and compiled binary for i386 GNU/Linux.
This package is based on "The Matrix Screensaver" for the 39/40 by Michaël De Coninck. The package is ported to the 50g and heavily modified. From the original description: "This is a screensaver based on the movie 'The Matrix'. Features cool effects like scrolling down the screen, splash screens and many other things." May run on other 49 series models; only tested on the 50g.
Security enhancement program. Wipes off any sensitive information from calculator memory which may be left there by some security application (MD5LIB for example).
