Welcome to PCjs

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.

Over time, PCjs emulations have expanded to include selected IBM PC Compatibles and more classic machines, such as Minicomputers, Programmable Calculators, Terminals, and Arcade Games. To learn more or contribute to these very modest preservation efforts, visit the PCjs open-source project on GitHub.

PCjs Highlights

A few hand-picked PCjs Machines are highlighted below, featuring hardware and/or software that may be considered historically interesting or unusual. You can browse more hardware and software combinations, and a small collection of related documentation, using the PCjs Explorer.
