Emulator of the ancient 8 bit microprocessor ISP-8A 500D/600D or more common "SC/MP" from National Semiconductor. The download contains all sources plus an executable Java Jar file to start right away. Some SC/MP hex dump examples are provided in directory "/etc" as well. The download also contains unit tests and some helping documentation (also in /etc). You may slow down the CPU operations, displaying the CPUs status register as LEDs, to watch the CPU working with its registers. The emulator also contains a VDU (video display unit) output / ASCII input simulation. There are some demos in /etc. And have a look to the NIBL / TINY BASIC interpreter in the TINYBASIC folder, most of the code is over 40 years old. Have fun, Theo Heinrichs

Jainja is a JVM (Java Virtual Machine) written in Java. The VM is developed by using the smallest possible subset of Java in order to run on top of multiple environments : Java SE, JavaME, Android, Javascript, and even natively.

A general purpose, object-oriented script language that compiles into code for a register based virtual machine. The language is quite similar to object-oriented high-level languages like Java and C#. The library is entirely self-sufficient and ANSI C compliant. It's main purpose is to be embedded in any application to allow automation of that application through scripting. An integrated C++ binding code generator allows you to create bindings for your application's classes in seconds. The integrated HTML documentation generator allows you to create documentation for your native bindings in seconds. The project is released under the zlib/libpng license. It has been in development for over 10 years and offers some powerful features. Extensive information, documentation, articles and code examples can be found at the developer blog.

Ela is a modern functional programming language that runs on CLR and Mono. It is implemented in 100% .NET and C#. Main project hosting is CodePlex: https://ela.codeplex.com/

SableVM is a clean-room, highly portable and efficient Java virtual machine. Its goals are to be reasonably small, fast, and compliant with the various specifications (JVM specification, JNI, invocation interface, etc.).

Dyalect is a dynamic programming language for .NET Core platform. It is lightweight, fast and modern. Dyalect (or Dy for short) is written in C# and has zero dependencies except for standard .NET Core libraries, which means that it can seamlessly run on Windows, MacOS and Linux. Moreover you can use the same binaries on any of these platforms! Dy runs on the top of its own high performance virtual machine. It compiles fast and can be used as an embeddable language or as a scripting language of your choice. It is also a good language to learn programming. Dyalect offers modern syntax, inspired by such languages as C#, Swift, Go and Rust, first class functions, coroutines, expressive modules, a dynamic type system with an ability to extend existing types with new functions and much more. Dy is shipped with a crossplatform interactive console. Main repo: https://github.com/vorov2/dyalect

Mouseth is a cross between the Mouse and Forth programming languages. The programs are compiled to a very compact, machine independant bytecode, which can then be run on its extremely small virtual machine.

Potato is a Squeak virtual machine completely written in Java. It is a derivative of JSqueak (http://research.sun.com/projects/JSqueak/) which was developed by Dan Ingalls. There is a blog on the project at http://potatovm.blogspot.com/.

ZLR is a Z-Machine interpreter designed to run modern interactive fiction games.

Avrora is a suite of tools for analyzing and debugging programs for AVR microcontrollers. It has support for a sensor platforms such as Mica2 and MicaZ, allowing wireless network simulation and allows dynamic instrumentation and static analysis.

Here you will find a collection of BCPL tools I've gathered from the net, cleaned up and ported to the Atari ST. This involved fixing bugs, reducing stack usage and making the code compile in 16bit via Pure C (Turbo C for the Atari ST). Source credits include: Martin Richards - BCPL Kit http://www.cl.cam.ac.uk/~mr10/ Robert Nordier (Translated interp to C) http://www.nordier.com/ Serge Vakulenko (Translated cg/syn/trn to C) https://github.com/sergev/b I'm sure there are other names, but those are the ones on the source files. The code now compiles clean for the Atari ST, so it should work for anything else.

Cola is a simple, weak-typed, object-oriented scripting language and execution library. Easy to learn, easy to implement, easy to read, can be dropped in to practically anything, and carries a very small memory footprint.

Dao is a lightweight and optionally typed programming language with many interesting features. It includes features that can make concurrent programming much simpler. It has well designed programming interfaces for easy embedding and extending.
