The Applicom driver was originally ported from SCO Unix in 1998, has had severe coding style issues, was broken for years in early Git history, and has no known active users. Later Applicom hardware only officially supports Windows and has been discontinued. The removals together eliminate approximately 19,500 lines of code, reducing future maintenance burden. ## Full article daily.dev links to this article rather than hosting it.
