trsmount allows you to mount TRS-80 disk images (.dmk, .dsk) as local directories on your computer. This enables you to read and write files to legacy TRSDOS and NEWDOS/80 disks using standard tools like Finder, Explorer, or the terminal.
Accessing data on vintage TRS-80 disk images often requires specialized tools or emulators. trsmount bridges the gap by integrating these images directly into your modern operating system.
This is particularly powerful when combined with modern development toolchains. For example, using Visual Studio Code with the TRS-80 gp Extension, you can compile your code and then seamlessly copy the resulting binaries (e.g., MYPROG.CMD) directly onto a virtual floppy disk. The driver automatically handles the conversion to TRSDOS format (e.g., MYPROG/CMD), making the workflow from "Code" to "Running on TRS-80" frictionless.
- Read/Write Support: Copy files to and from disk images.
- Format Support: Handles DMK and DSK container formats.
- Filesystem Support: Supports TRSDOS 2.3 and NEWDOS/80 filesystems.
- Superzap Utility: Includes a sector-level inspector for low-level analysis.
- Catasm Utility: A specialized viewer for TRS-80 Assembler source files, handling high-bit ASCII and formatting.
- macOS: Primary target platform. Requires FUSE-T (recommended) or macFUSE.
- Linux: Planned for future releases. Contributors are welcome to help verify and extend support!
- Python 3.6+
The preferred installation method on macOS is via Homebrew:
brew tap TechPrototyper/trsmount
brew install trsmountUntil the Homebrew formula is published, or for Linux users, you can use the included setup script. This script creates a virtual environment and installs the necessary dependencies.
./setup.shThis project is configured as a standard Python package. You can install it in editable mode:
pip install -e .trsmount disk.dmk ./mntYou can now access ./mnt to see the files. When finished, unmount the directory:
umount ./mnt(Note: On macOS, you can also use diskutil unmount ./mnt)
Use the superzap utility to view raw sectors of a disk image:
superzap disk.dmkTRS-80 assembler files often use high-bit ASCII characters for compression and specific formatting. catasm allows you to view these files in a readable format on modern systems.
# View a file
catasm FILE.ASM
# View without line numbers (useful for diffs or re-assembly)
catasm -n FILE.ASM
# Add colons to labels (for compatibility with some modern assemblers)
catasm -c FILE.ASM
# Combine options and pipe to an assembler (e.g., zmac)
