Virtual T is a TRS-80 Model 100/102/200 emulator that runs on Windows, Linux, and Macintosh. The goal of Virtual T is to provide 100% hardware emulation so any existing programs will run. It also adds powerful development and debugging tools.

z390 Portable Mainframe Assembler and Emulator

Implementation of ANSI Standard MUMPS 1995 and ISO/IEC 11756 for FreeBSD, OSX and linux. Also on the Raspberry Pi (ARM) under debian and Windows under cygwin. This is the post-relational database.

JNode is a Java New Operating system Design Effort. JNode is a simple to use and install Java operating system for personal use on modern devices. Any java application runs on it, fast and safe. See our homepage for additional information.

The MDK provides a simulator of D. Knuth's MIX computer, and a development environment to write, run and debug MIXAL programs on it.

ATasm is a 6502 command-line cross-assembler that is compatible with the original Mac/65 macro assembler released by OSS software. The aim of ATasm is to provide Atari home-brew coders with a comfortable and powerful toolset.

several vaguely related projects worked on by me: a 3d engine with a javascript-like scripting language (pdsys); an older scheme dialect (vmsys); ... (2009-04-28: I have been gone for years, may try to put up some newer stuff...).

amforth is an extendable command interpreter running on AVR ATmega and TI MSP430 microcontrollers. The Risc-V and ARM architectures are ascending. Turnkey actions for IoT workloads are possible as well. The command language is close to the Forth 2012 standard.

This ASN.1 compiler turns ASN.1 specifications into C code. The asn1c is shipped together with conformant BER/DER/XER/PER codecs. The X.509, GSM TAP3, MEGACO, RRC and LDAP encoding and decoding examples are part of the source code distribution. NOTE: THE asn1c PROJECT HAS LARGELY MOVED TO GITHUB: http://github.com/vlm/asn1c

CDK4NIOS stands for Cross Development Kit for Altera's soft core processor NIOS and should you support with a comprehensive Assembler and C/C++ development environment under Linux. It will present only free of fee tools, so you can use it without risks.

ZASM is a 2 pass assembler for Zilog's 8-bit CPU Z80. Supported platforms: Unix-style OS, e.g. MacOS X, Linux, BSD. Special support for ZX Spectrum emulator file formats. Binary or intel hex file output.

A collection of tools to tokenize PBASIC source code and send it to a BASIC Stamp microcontroller.

Erc is an interpreted link-oriented language. Majic is a java-based interpreter for Erc, and Majicc is a c++ based compiler for Erc which uses the Majic libraries.

GNUDE is a complete suite of GNU C, C++, Fortran, and Java Cross Compilers, and the GDB CPU Simulator and Debugger for embedded microprocessor applications development. Targets development for ARM7, ARM9, and XScale applications.

Write programs as graphical dataflow charts instead of text. Compile them to any programming language you want. Besides this project includes the most efficient tree-based sorting algorithm that is possible. Originally developed on a CTOS Color NGEN, at first in Pascal, later ported to C, finally - 20 years later - ported to Linux. Currently it's still not really system independent. But it's intended that further releases will cure this.

ARIO is a C++ library for reading and producing archive files, which are commonly used as libraries of relocatable object files. See also ELFIO project.(http://sourceforge.net/projects/elfio)

This project aims to create an ARM processor emulator for Linux/x86, utilising dynamic binary translation techniques for maximum speed.

AllInOneRuby creates an Windows or Linux executable that includes both the Ruby interpreter and the runtime libraries. Why? Because it's sometimes not easy, or allowed to do a complete Ruby installation. That's where AllInOneRuby comes in.

Compiler for message-passing network protocols, currently based on UDP. APC is written in Python and produces C code. It includes a C run-time library.

Netflow analyzing tools : JXColl - collector for Netflow (or XML specified) data Analyzer - front-end application for providing an user interface and output (graphs, statistics, etc.)

COOK is a software build-automation tool made with a goal of letting you, the programmer, to utilize the most elegant and powerful programming language - Common Lisp - for managing your software builds. You write a recipe file which describes what objectives must be constructed. COOK will load and process this file, then produce either a regular Makefile or a Bourne Shell script, which will actually perform the task of building and installing your targets.

CORBA for PHP is a PHP Extension to use CORBA objects in PHP5(Zend Engine 2). It uses MICO as its ORB and will also provide an Idl-to-PHP language mapping specification and compiler. For a PHP4 CORBA support look at the great Universe-phpext.

RPC (Remote Procedure Call) system with C language support, own network protocol, automatic parallelization, SSL support and other features.

Chor is a strongly-typed choreography programming language for distributed systems. In Chor, the behaviour of a system is written down as a global program (a choreography) where all the message exchanges between the participants are explicit. Choreographies are statically checked against protocol specifications, given as types, enabling type-directed global programming. Finally, Chor supports the automatic generation of systems from a choreography. With Chor, you do not have to worry about asynchronous communications or protocol compliance anymore. The language is based on strong theoretical bases, so that you can let its compiler do the jobs of checking your global programs and generating correct implementing code for you!
