history

Project history and usage

DASM is a C macro assembler for 8-bit processors used in retrocomputing, console homebrew, and cross-assembly workflows.

Project history

The official DASM site traces the assembler to Matthew Dillon in 1987-1988, followed by extensions and several maintainer eras through the 1990s and 2000s. The project moved its source and releases to GitHub in 2019.

Adoption history

DASM's long life comes from its support for processors and machines that matter to 8-bit development, including MOS 6502 and 6507 systems, Motorola-family chips, Hitachi HD6303, and Fairchild F8. The official downloads include Linux, macOS, Windows, and Raspberry Pi OS binaries.

How it is used

It is used as a command-line cross-assembler, with included console-specific headers and common macros for systems such as the Atari 2600, Atari 7800, and Fairchild Channel F.

Why package nerds care

For package history, DASM is the rare tool where modern package managers carry a living utility from late-1980s assembly culture into current retrocomputing and homebrew-console build chains.

Timeline

  • 1987-1988: Matthew Dillon started DASM.
  • 1995: Olaf Seibert extended DASM.
  • 2003-2008: Andrew Davie maintained DASM.
  • 2008-2015: Peter Frohlich maintained DASM.
  • 2019: Source code and releases moved to GitHub.
  • 2026: v2.20.17 was published on GitHub.

Related projects

  • DASM is commonly associated with 8-bit targets such as Atari 2600, Atari 7800, and Fairchild Channel F development.
