I can confirm, I know a teacher who used DRDOS 7, WP 5.1, and Harvard Graphics to make all their classroom handouts. They use more modern Linux / Debian stuff for actually browsing the web and other computing tasks, but keep several reliable DOS machines for school prep, because of being burned on Windows and Linux having problems (mostly related to poorly timed updates, or fsck'ing a disk) which used up hours on a night when new material had to be ready by the next morning.
