Twenty years ago this week, as Microsoft announced that it would end support for the MS-DOS operating system, James Hall announced to the world that he intended to create a public domain version of the OS in order to keep the universe of character-based DOS software alive. Hall’s “PD-DOS” project eventually became FreeDOS, which today supports an ecosystem of developers, retro gamers, and diehards who will give up their WordStar when you pry the floppies from their cold, dead fingers.

We visited the world of decades-old tech... but wouldn't want to live there.
In tribute to the project's two decades (and to those brave souls who keep the DOS fires burning), I decided to spend a day this week working in FreeDOS.
