PCjs

Overview of PCjs

PCjs is a comprehensive web-based emulator that recreates classic computing hardware and software from the 1970s and 1980s using JavaScript technology. This innovative platform allows users to experience vintage computer systems with their original slow processors, low-resolution displays, and primitive sound capabilities directly within modern desktop or mobile browsers. The emulator serves as both an educational resource and nostalgic playground, preserving digital history through accurate emulation of iconic machines and their software environments.

The platform has expanded beyond its initial focus to include various IBM PC compatible systems, minicomputers, programmable calculators, terminals, and classic arcade games. As an open-source project hosted on GitHub, PCjs encourages community contributions to its preservation efforts while providing accessible retro computing experiences without requiring specialized hardware or complex setup procedures. This makes it particularly valuable for Emulator enthusiasts and technology historians exploring Retro Games and historical computing platforms.

How to Use PCjs

Using PCjs requires no installation or registration – simply navigate to the website and select from the extensive collection of emulated systems available through the PCjs Explorer interface. Users can browse categorized machines including IBM PC compatibles, DEC minicomputers, TI programmable calculators, and various arcade systems, then click to launch the emulation directly in their web browser. The interface provides access to original software ranging from early business applications like VisiCalc and Lotus 1-2-3 to classic games such as Zork and Wolfenstein 3D, with many systems including documentation and contextual information about their historical significance.
