Historique du projet

The project is hosted on GNU Savannah/NonGNU, with its homepage emphasizing a free, easy-to-expand, easy-to-use assembler whose source can be read, modified, and redistributed. That framing fits the retrocomputing and embedded-toolchain world, where developers often need transparent tools for old instruction sets.

The Savannah cgit history shows continued maintenance into 2021, including fixes around undocumented IX/IY opcode handling and bug branches. The public history is not heavily narrative, but it shows a long-lived utility maintained through the free-software hosting ecosystem rather than a vendor IDE.

Historique d'adoption

z80asm persists in package managers because Z80 code persists: retrocomputing, emulator projects, calculator and handheld work, hobby operating systems, embedded experiments, and ROM hacking all need a scriptable assembler.

The input facts for this run list z80asm in Homebrew, Debian, Fedora, and Ubuntu, which is the key adoption signal for a small classic-CPU assembler: it is available wherever users expect to assemble old 8-bit code on modern systems.

Modes d'utilisation

Users write Z80 assembly, usually set an origin with org, define bytes and words with directives such as db and dw, include source or binary files, use conditionals and macros, and assemble to a binary output suitable for ROM images, emulators, or target devices.

The official usage page says command-line help documents invocation, while the web docs focus on writing assembly for this assembler. That split is typical of small Unix tools: install the command, use --help for options, and read the project pages for syntax details.

Pourquoi les passionnés de paquets s'y intéressent

z80asm is significant because it keeps a 1970s CPU architecture usable from modern Unix package managers. It is a small bridge between historical hardware and contemporary reproducible builds.

It also has the classic assembler-package shape: tiny binary, no service, no credentials, little runtime state, but high value when a build pipeline needs exact bytes.
