ArtfulType: Markdown Writing App for the 68K Macintosh

Sean Malseed — “Action Retro” on YouTube — created a Markdown editor for the original Macintosh. Source code on GitHub; intro video on YouTube. It’s written in C, not Pascal, and uses the modern Retro68 GCC-derived compiler.

I absolutely love that this exists. I don’t like the actual app at all. I guess “full screen” mode is the point of some “distraction free” editors, but I for one would never look twice at a Mac app that didn’t use windows. Full-screen mode just wasn’t a thing back then, except for games. ArtfulType is not a Mac-assed 1984 Mac app.

If I wanted to write in Markdown on a classic Mac, I’d use BBEdit, which was the app I originally created Markdown for use in. And one of two apps I primarily still use it in. But BBEdit won’t run on an original 128 KB Macintosh, because Rich Siegel didn’t create it until 1989, and the earliest public version was BBEdit 2 in 1992. BBEdit 2.1.3 does run in System 5 on Infinite Mac, but crashes if launched on System 3. I 100 percent see the appeal of using a 1980s retro Mac, but I don’t see the appeal of using one that can’t run System 6.
