HackNet (Hacknet OS) is a retro web-simulation of a stylized ARPANET/USENET, circa 1985-1990, a transcontinental network operated by the US Military, stretching from US to UK and Norway by sattelite.
It is a full multi-user simulation, including simulated hosts from the early net, many of files from the era and more. The simulation takes inspiration from the "TeleHack" and "Hacknet" game and other terminal-focused games.
The main focus of the project is to educate about internet history and technology.
