Personally, I wouldn't classify DOS as retro technology, but that's more due to the fact that my birthday dates back to somewhere in the mid-70s. 😭

Nevertheless, interest in DOS is definitely high in the retro scene, and for various reasons other than #gaming. 

Angelo Pesce aka c0de517e has taken it upon himself, to equip a laptop (of an equally profound age) with DOS, and grants us a fine insight into his experiences, as well as the accompanying personal background story.

His blog post is nice reading material for a few minutes in between. In addition, there are also some interesting suggestions that will help, to set up a pure DOS machine in 2022.

Give it a shot.
