FRAME3DD is a program for the static and dynamic structural analysis of two- and three-dimensional frames and trusses with elastic and geometric stiffness.

Agena is an easy-to-learn procedural programming language designed for science, scripting, and many other applications. Binaries are available for Windows, Linux, Solaris, OS/2, Mac OS X, Raspberry Pi and DOS.

hexcompare is a curses-based utility to compare and identify differences between two binary files. These differences are then represented visually with an interactive block diagram.

A Sequenced Binaural Wave Generator for Linux+Windows. May be used to generate sounds that entrain the brain's waves to oscillate at selected frequencies to aid in relaxation, lucid dreaming, meditation, clear thought, out-of-body experiences + more

BEYE (Binary EYE) is a free, portable, advanced file viewer with built-in editor for binary, hexadecimal and disassembler modes. It contains a highlight AVR/Java/i86-AMD64/ARM-XScale/PPC-64 and other disassembler, full preview of MZ,NE,PE,ELF and other.

XFUNC 2.2 is a IBM PC program for DOS. It is an aid to Electronics Engineer who calculates transfer functions using symbolic algebra. It compute the frequency domain transfer function of a circuit in symbolic format, given a circuit description netlist in linear model. Calculate AC or DC symbolic transfer function in S-domain for Linear Circuits or Z-domain for Switching Circuits. Accept resistors, capacitors, inductors, dependent sources, ideal opamps, and ideal switches. Component values can be real numbers, symbols, or user defined symbolic expressions. Frequency domain results can be transformed to time domain via Inverse Laplace or Z Transform. Transformation between S-domain and Z-domain results can be done via Forward or Backward Derivatives (Euler Transform), Bilinear, or Impulse Invariant Transforms. Provide Bode, Gain-Phase, Nyquist, Pole-zero, Impulse, and Step response plots. Plot ranges can be set manually or automatically.

Spice+ is a general-purpose circuit simulation program, based directly on SPICE 3F.5 from the University of California (Berkeley). An improved version of Spice for DOS, Windows and Linux. http://spicep.sourceforge.net

A simple DOS program pack that can very smoothly take some engineering calculations. It's fully written in russian, but I working over it's english version.

FreeBasic Math library

FoxCalc is a calculator with a text user interface (TUI), compiled for DOS. It supports a mouse, and uses the GMP library, therefore its results are highly accurate. FoxCalc is distributed as a zip FreeDOS package. That way, it can be easily installed using the FreeDOS package manager.

kalc is a programmable scientific calculator, using RPN (Reverse Polish Notation). Its behaviour imitates a HP48/HP49 calculator. Works with real and complex numbers, unlimited size integers, arbitrary-precision real numbers and more.

Stripe Snoop reads the contents of a magstripes (Track 1, 2, or 3) through different hardware interfaces and not only displays the contents, but uses a CDDB-like database of card formats to try and figure out what the contents mean.

SPECI-SPICE is a subset of SPICE intended to run on low powered computers like Amstrad CPC, ZX Spectrum, CP/M machines, old PC machines, some programmable calculators,etc. by keeping most important functionality of SPICE 2.

FOOL is a Fuzzy system development tool with interactive 'foolproof' graphical user interface.

Common Hardware Recovery Solutions by Ukrainian-Russian network

This is a project that simulates the German Military Enigma machine during WWII.. It is a project for beginers to learn to program and to meet people. If anyone is interested in helping, please email me @ dustin@rockhill.org

FreeDOS Reisdent Calculator -- programmer's TSR calculator.

IBAP is a structural beam analysis software that can be used by Civil, Mechanical and Structural Engineers, Beam designers and Engineering students for both professional and academic purposes.

BASIC library for large-integer arithmetic, plus some number theory modules.

ABE is a small, fast and convenient program for visualizing and modeling experimental bioassay data. The data can be modeled using either polynomials or a more specific four-parameter model based upon the standard, sigmoidal dose-response curve.

Compasso é um programa desenvolvido em C para o controle de motores de passo através da porta paralela (LPT). Juntamente com o programa é disponibilizado um esquema com uma montagem de circuito para ser utilizado.

Digitizer program to manually digitize data from graphic images. Allows for multiple calibrations and source image files for a single set of data series. Also includes an auto-export feature to streamline interoperability.

Real-time EEG data acquisition and control software for event related potential (ERP) researchers. Writes data in ERPSS (UCSD) raw and log format and displays, in real time, in X windows.

Equalculator is an equation calculator. It is currently in the "pre-alpha" stage of development, so don't expect it to do miracles. You type in your equation, it will ask you for the variables and Voila!, it gives you the answer.
