A digital preservation project brings classic computers from the 1970s and 1980s directly to the browser. This is PCjs, an emulator written in JavaScript that recreates everything from the original IBM PC to minicomputers, programmable calculators, and terminals.
According to pcjs.org, the emulator was created by Jeff, who gathered hardware and software he interacted with in his youth. Everything runs in the comfort of a desktop or mobile device, with no installation required.
PCjs is not limited to the IBM PC. The collection has expanded to include IBM compatibles, classic machines, arcade games, and public domain software. The goal is to offer a faithful experience: slow CPUs, low-resolution screens, and primitive sounds.
All code is open source. The project is hosted on GitHub, where anyone can contribute or study the inner workings. To browse hardware and software combinations, PCjs Explorer organizes the collection with related documentation.
The initiative is an example of how JavaScript emulation can democratize access to computing history. Instead of relying on old and fragile hardware, a modern browser is all that is needed.
PCjs is also an educational tool. Developers can understand how old systems worked, from DOS booting to running shareware programs. The experience is immersive and didactic.
For those who wish to support, the site invites visiting the GitHub repository. Digital preservation is modest but essential to keep the memory of early microcomputers alive.
The emulator has been running for years and continues to receive updates. The community around the project grows, attracting retrocomputing enthusiasts and researchers.
In a world of increasingly ephemeral hardware, projects like PCjs ensure that the machines that shaped the industry are not forgotten. Just open the browser and travel back in time.
