GCBASIC is an open-source BASIC compiler for 8 bit Microchip PIC, Atmel AVR legacy, AVRDx and LGT microcontrollers.
See https://ko-fi.com/post/The-Story-of-GCBASIC-Making-Microcontroller-Progr-D1D319SJ72 for story of GCBASIC.
This is a continuous release project. The latest release is always available. This will give you the most complete development toolchain to create and program 8-bit PIC, AVR and LGT microcontrollers.
We have added new capabilities that make GCBASIC the...
A machine code manipulation library for Intel 64 and IA-32.
...The FCML library is free for commercial and non-commercial use as long as the terms of the LGPL license are met. Currently it supports such features as:
- A one-line disassembler
- A one-line assembler
- An experimental multi-pass load-and-go assembler (Multi line!)
- Support for the Intel and AT&T syntax
- An instruction renderer
- An instruction parser
- Instructions represented as generic models
- UNIX/GNU/Linux and Windows support
- Portable - written entirely in C (no external dependencies)
- C++ wrapper
- Supported instruction sets: MMX, 3D-Now!...
In a fit of recreational programming, I wrote this 8080 assembler. God only knows why I picked a 30 year old processor.... I guess I just loved that old processor.. Maybe thats why I have 2 of them in the attic. ..
pyz80 is a z80 cross-assembler written entirely in Python. It accepts text files with the syntax of the Sam Coupe's popular COMET assembler, and outputs a disk image suitable for loading in SimCoupe or transferring to floppy disk for use with a real Sam.

An open source COBOL compiler for the PC x86-32 platform.
Generates GNU assembler and requires GCC to produce a binary.
Supports Linux, BSD and MinGW 32 bit platforms.
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.
Atar8 Tools is a collection Atari 8-bit related of command line tools for Posix compatible environments:
- Franny is an ATR disk image editor. Supports AtariDOS II disk format (partially) and SpartaDos 2 disk format.
- Yvonne is an Atari picture viewer / converter.
- ZooEY is a cross assembler designed for 6502 processors. Binaries are generated specially for Atari 8-bit systems (AtariDOS II and SpartaDOS X formats supported). This tool is compatible with Quick Assembler, one of most popular assembler in Poland.
PYthon to ASsembler TRAnslator. At this moment supports Microchip PIC16 instruction set only. Its main goals are: to support a wide range of microcontrollers and processors, to generate compact and effective code.
VirtuAL3101 provides a series of tools to develop effects using the AL3101 DSP from Alesis. It includes an assembler/disassembler, a simulator, an application generator with its graphical interface and various effects.
Tas is a multi-platform multi-lingual assembler for the Freescale eTPU intelligent timer module. The assembler has a C compatible pre-processor for easy integration with host CPU code. The assembler also supports the original TPU module.
Jack is an optimizing C compiler for the Jackal 3.0 ISA. The Jackal 3.0 ISA is the target architecture for UVa's Advanced Digital Design Course. JackCC is ready for production use. Additionally, I've written an assembler/simulator: jackas
SoftWire was the precursor to TransGaming's SwiftAsm. SwiftAsm is an optimizing run-time x86 assembler that can be used as a JIT compiler back-end for scripting languages, or for dynamic code generation of efficient processing pipelines.
JTools.Ruby is easy way to access Java 2 class-files via scripts written in Ruby language. There are class-file disassembler, assembler and simple Ruby to Java bytecode compiler. The work is at the start point.
Chasm is a language using assembler meat with C style bone. It provide
the C style flow control statement to make assembler code easier to write
and easier to maintain. All the register/memory modify code is
in the assembler, give the programmer the de
NasmSharp is an open source effort to build a x86 assembler written in pure C#. Primarily it is a C# port of well known x86 assembler NASM, written in ANSI C.
Involvement of some experienced C# programmers is highly appreciated.
