The Register just wrote an article on creating a bootable USB version of DOS to make a distraction free writing machine. [1]

They include three freeware word processors "MS Word, Arnor Protext, an outliner, and the WordPerfect Editor" and released it on Github [2]. But, they mention other word processors in the article and their current status (free/paid/etc).
