PCjs Machines: Relive the 1980s Computing Era in Your Browser

PCjs Machines

I created PCjs to let you experience the slow CPUs, low-resolution displays, and primitive sound effects of the 1970s and 1980s directly in your web browser. From the original IBM PC to classic minicomputers, programmable calculators, and arcade games, this open-source project preserves a wide range of historical hardware and software for everyone to explore safely.

"PCjs uses JavaScript to emulate a small collection of hardware and software that I grew up with in the 1970s and 1980s, allowing you to experience their slow CPUs, low-resolution displays, and primitive sound effects, all in the comfort and safety of your desktop or mobile web browser."
