## Project history and usage

asm6809 is a portable macro cross-assembler for Motorola 6809 and Hitachi 6309 code. The upstream manual describes those processors as most commonly encountered in Dragon and Tandy Colour Computer systems.

### Project history

The upstream changelog records prereleases beginning in August 2013 and an initial 2.0 release on April 30, 2014. Early 2.x releases added a manpage, macro and expression improvements, conditional assembly, output options, and tests.

The project has remained active in a small-retro-tooling style rather than moving to a large hosting forge. The official site publishes tarballs, Windows builds, a Git repository, HTML/PDF/text manuals, and a detailed changelog on the author's 6809.org.uk domain.

### Adoption history

asm6809 is packaged by Homebrew and Fedora according to the input package facts, while the upstream site also offers Debian snapshot builds, an Ubuntu PPA, and Windows binaries. Homebrew analytics are small, but that is normal for a specialized cross-assembler aimed at 6809 and 6309 retrocomputing.

### How it is used

The command reads one or more source files and performs enough passes for symbols and addresses to stabilize. It can emit raw binary, DragonDOS binary, CoCo RS-DOS/DECB segmented binary, Motorola S-record, and Intel HEX output, plus optional listing, exports, and symbol files.

### Why package nerds care

For package nerds, asm6809 is a neat example of a retrocomputing tool that still behaves like a conventional Unix package: source tarballs, a manpage-style manual, distro packages, Windows zips, and a plain Git repository. It is also domain-specific in a useful way, preserving Dragon and CoCo workflows without pulling in an emulator or full IDE.

### Timeline

- 2013: First prerelease recorded in the upstream changelog.
- 2014: Version 2.0 initial release.
- 2017: 2.10 added FQB and expression/table fixes after several 2016 and 2017 compatibility releases.
- 2019: 2.12 added `--max-passes` and S-record checksum fixes.
- 2025: 2.17 released, fixing use of `*` as current PC in expressions.

### Related projects

- The upstream homepage names LWTOOLS/LWASM and A09 as similar assemblers, and points to XRoar as an emulator that can run asm6809 output.
