ZX Spectrum emulator
It's a ZX Spectrum emulator written entirely in Assembler. It runs under MS-DOS, and pretty well also in Windows and MS-DOS emulators, like Dosemu and Dosbox. It's the first emulating the Inves Spectrum + (a Spanish clone) You can try a newer and better emulator, made also by me, for Unix systems (Linux, Mac, Raspberry Pi and others) and Windows here: http://sourceforge.net/projects/zesarux/

Scanning Probe Microscopy Controller and Data Visualization Software
GXSM -- Gnome X Scanning Microscopy: A multi-channel image and vector-probe data acquisition and visualization system designed for SPM techniques (STM,AFM..), but also SPA-LEED/LEED/LEEM data analysis. A plug-in interface allows any user add-on data-processing and special hardware and instrument support. Latest: NC-AFM simulation support via math-plugin. Based on several hardware options it supports a commercially available DSP hardware and provided also Open Source Code for all the low level signal processing tasks and instrument controls in a most flexible and adaptable manner. All latest software is available via CVS only or Live Demo/Install CD: http://www.ventiotec.de/linux/GXSM-Linux.iso
MplayerXP is branch of well known mplayer (http://mplayerhq.hu) which is based on new (thread based) core. Main goal of this project is to achieve smoothness of video playback due monotonous CPU loading.
Convert PSID and RSID files into C64 executables
PSID64 is a program that converts PSID and RSID files into C64 executables. This allows users to play PSID and RSID files (originally used by the PlaySID program) on a real Commodore 64 computer or emulator such as VICE.
Custom firmware and IDE for the VEX Cortex Microcontroller
This project has been moved to http://pros.cs.purdue.edu/ PROS is a lightweight and fast alternative operating system for the VEX Cortex Microcontroller. It features multitasking, low-level control, and Wiring compatible functions to harness the full power of the Cortex. With a real-time kernel based on FreeRTOS and a development environment built on Eclipse CDT, PROS uses proven software to increase the reliability and usability of the VEX development system across all three major computing platforms. PROS is currently under active development to make it usable for VEX high school and middle school teams. PROS is intended for advanced VEX users seeking to move beyond competing environments. Eclipse and FreeRTOS have their own licensing agreements. Please see http://www.eclipse.org/legal/epl-v10.html and http://www.freertos.org/a00114.html for details.
Libecc is an Elliptic Curve Cryptography C++ library for fixed size keys in order to achieve a maximum speed. The goal of this project is to become the first free Open Source library providing the means to generate safe elliptic curves.
16 bit Forth for PC. No OS required.

RTOS for Critical Systems
Pharos is a free open-source Real-Time Operating System for Critical Systems with the following characteristics: -Security: With memory and enhanced time partitioning. Each partition protected with hardware MMU/MPU and operating in user mode -Quality: Low cyclomatic, high comments, low nesting level, MISRA. -Mixed Criticality: Partition isolation. Native support for sporadic, periodic and aperiodic threads under a fixed-priority preemptive scheduler, including execution time protection (threads are prevented from executing for more time than they are configured to) -Determinism: Hard real-time determinism, most calls areO(1) and very few cases are O(Log(N)) - they are well identified in the user manual. Dynamic memory free Pharos takes ARINC and moves it one step further, improving responsiveness and isolation. Supports ARM R5, M4, 926EJ-S. We are a group of enthusiastic software developers that also implements client custom software. Contact: firstname.lastname@example.org
