Ask HN: Who's still keeping a DOS machine up because the business depends on it?
A Hacker News discussion thread asks who still runs DOS machines that their business genuinely depends on. The prompt invites stories of legacy computing: factories, labs, or offices keeping decades-old MS-DOS or PC DOS systems alive because critical software or hardware was never ported to modern platforms. Commenters typically share examples of industrial controllers, embedded equipment, and the challenges of maintaining obsolete hardware, with debate over why such systems persist and how risky they are.
Why now: A popular Ask HN post (around 200 upvotes) sparked engagement from readers with legacy-system experience and nostalgia for old computing.
