TRURL is a suite of desktop calculators with reverse Polish notation (RPN) written in Object Pascal. Additionally, it comes with a free reusable class library (RPN Engine) as a toolbox for creating your own calculator. TRURL is an acronym for "TRURL is a Reusable Universal RPN Library". Class Libraries: • RPN Engine: Full-featured calculation engine for Pascal-based RPN calculators • Segmitator: Library for virtual seven-segment displays Applications: • TRURL A: Simple demo app for the RPN Engine • TRURL B: RPN calculator in the design of the famous calculators by Dieter Rahms for Braun • TRURL G: Desktop RPN calculator inspired by the UI of the DSKY unit of the Apollo Guidance Computer (AGC)

Remember when you wrote your games in Pascal? Well continue that fine tradition by using JEDI-SDL! Which works with Delphi, Kylix, Free Pascal, Gnu Pascal and TMT Pascal. Cross-platform game develpment has never been easier!

This application inverts matrices with the Gauß-Jordan elimination. It supports matrices up to a size of 10x10. It displays the computition and of course the solution. Support for fractions is coming soon

Achelous is attempt to clone Mac OS X for the Intel X86 Chipset. There are currently two teams working on the project: the Kernel team and the GUI team.

The PUMA Repository is a collection of Pascal units for medical informatics. It contains reusable source code for a wide field of health-care application development. The code includes a support engine for the European Data Format (EDF and EDF+), converting functions for units of measurement and an HL7 engine. PUMA is compatible with Lazarus and Free Pascal. Some of the units also support other Pascal implementations including Delphi, winsoft Pocket Studio and other compilers.
