PCjs is a JavaScript emulation project that lets you run iconic computers and software from the 1970s-80s in your web browser. It offers a nostalgic experience with low-resolution displays, slow CPUs, and primitive sound effects. ## Supported Systems The project supports a wide range of classic hardware and software including IBM PC compatibles, programmable calculators, terminal emulators, and arcade games. Notable examples include Space Invaders, VisiCalc, and Microsoft Adventure. ## User Interaction Users can explore different hardware-software combinations via PCjs Explorer and access original documentation. For instance, you can experience the 1978 TI-57 calculator or use Lotus 1-2-3 from 1983. ## Software Collection The platform hosts historic software like PC Magazine Utilities (1987), PC-SIG Diskette Library (1990), along with applications such as Norton Utilities 2.0 (1983) and Microsoft Word 1.15 (1984). Classic games include Oregon Trail and Wolfenstein 3D. ## Technical Infrastructure Built entirely with JavaScript, PCjs runs smoothly on modern browsers. The open-source project welcomes developer contributions on GitHub. Emulations accurately replicate the limitations of original hardware. ## Preserving Digital Heritage PCjs fills an important gap in digital archaeology. It offers younger generations a chance to experience computer history while helping preserve legacy software. The project contributes to safeguarding our technological heritage. ## Sources covering this story - https://www.pcjs.org/ — --- _Summary written by Brifing from the original reporting.
