ActionRetro has published ArtfulType, a Markdown writing app for classic 68K Macintosh systems, aimed at people who would rather draft text on a Mac Plus than pretend a modern Electron editor is lightweight. The project’s GitHub README describes it as software for System 6 and System 7 machines, built to run from a BlueSCSI device on a Mac Plus or similar compact Mac.
The point is practical, at least within the strange and noble constraints of vintage computing. ArtfulType saves ordinary Markdown files, so text written on a compact Mac is still just plain text elsewhere. The app offers two editing views: a default writer view that hides Markdown syntax while applying visual styling, and a Markdown view that shows the raw source.
According to the project page, writer mode formats common Markdown as the user types, including bold, italic, code, headings and links. Links can be entered inline using Markdown syntax or applied to selected text through the Style menu. The app also includes cut, copy and paste, multi-level undo and redo, remembered zoom settings, and open/save through the classic Mac File Manager.
Old Macs, modern packaging problems
Distribution is half the story here, because 68K Macs do not install software like a 2026 laptop. ActionRetro provides paths for three setups: real hardware with BlueSCSI, real hardware without BlueSCSI, and Mini vMac emulation.
For BlueSCSI users, the README says to copy an HD1_ArtfulType.hda image to the SD card. The HD1_ prefix follows BlueSCSI’s convention for assigning a disk image to SCSI ID 1. Once the Mac boots, the user launches ArtfulType from the Finder. The same disk image also includes Disk Copy 4.2 and an ArtfulType 800K image for writing a physical floppy.
For machines without BlueSCSI, ActionRetro says users can write ArtfulType-800K.dsk to an 800K floppy and boot from it. For emulation, the project points to Mini vMac configured as a Mac Plus, using either a 20MB disk image with System 7.1, the app, Disk Copy and the embedded floppy image, or an 800K System 6.0.8 boot floppy containing only the app.
Built with Retro68, licensed in pieces
The repository says ArtfulType is built with Retro68, a GCC-based cross-compiler for classic Mac OS. The repo also includes shell scripts for deployment, BlueSCSI image creation and release packaging. GitHub lists the codebase as mostly C, with smaller amounts of Shell, Rez, Python and CMake.
The project uses split licensing. ActionRetro lists the code under GPLv3, while the ArtfulType name, branding, icon and artwork are covered by a separate all-rights-reserved assets license. The README also includes an AI disclosure stating that Claude Code was used in creating the software. The GitHub repository lists Action Retro and Claude as contributors, and several commits visible on the project page are co-authored by Claude Sonnet 4.6.
As of the GitHub listing, ArtfulType has two tagged releases, with v0.1.2-alpha marked as the latest release. The repository shows 76 stars, 8 forks and 28 commits on the master branch. The most recent listed commit, dated July 6, 2026, added a video overview to the README.
