history
Project history and usage
cpmtools is Michael Haardt's collection of utilities for accessing CP/M file systems from modern host systems. It is a retrocomputing and disk-image maintenance package rather than an emulator.
Project history
The upstream README and homepage describe cpmtools as a package for accessing CP/M file systems in a style similar to mtools for MS-DOS file systems. It includes commands for listing, copying, removing, changing attributes and permissions, creating, checking, repairing, and viewing CP/M file systems.
The manual pages identify Michael Haardt's copyright beginning in 1997 and note a Windows port by John Elliott. The 2026 cpmtools 2.24 release continues maintenance with filesystem, filename translation, mkfs, fsck, LibDsk, and diskdefs updates.
Adoption history
The supplied package facts list cpmtools in Homebrew, Debian, Ubuntu, Fedora/dnf, and MacPorts. That packaging spread reflects its role as a practical bridge between current Unix-like hosts and CP/M disk images used by retrocomputing communities.
How it is used
cpmtools is used to inspect and modify CP/M disk images, exchange files with simulators or floppy devices, and define disk geometries through diskdefs. The upstream documentation says all CP/M file system features are supported, while password protection is exposed as data rather than enforced.
Why package nerds care
For packagers, cpmtools is notable because it preserves access to non-self-describing CP/M disk formats. The diskdefs file is part of the package interface: CP/M generally does not store enough format information in the filesystem, so distributions must install the definitions file where the tools can find it.
Timeline
- 1997: Manual-page copyright begins for Michael Haardt's cpmtools.
- 2022: Upstream files list cpmtools 2.23.
- 2026: Upstream files list cpmtools 2.24 with diskdefs and filesystem fixes.
Related projects
- mtools is cited by upstream as the analogous package for MS-DOS file systems.
- LibDsk support is mentioned in the 2.24 changes and command manual.
