PCjs is the home of PCx86, the original IBM PC emulator that runs in your browser.

PCjs is also my homage to a small number of machines that I grew up with. Those machines include:

• 6502-based Microcomputers
• 8080-based Microcomputers
• Arcade Machines
• DEC Minicomputers and Terminals
• IBM PC and PC Compatibles
• Texas Instruments Programmable Calculators
• LED Simulations (Lite-Brite, Game of Life, etc)

along with some hand-selected software, including some from my own personal collection, used here for archival/demonstration purposes only.

To learn more about what you can do with the repository, see the PCjs Wiki, which covers topics such as:

• Using a Local Web Server
• Compiling PCjs Source Code
• Adding Machines to Web Pages

Topics covered in the repository itself include:

• PCjs Disk Images
• PCjs File Images
• PCjs Archive Utility
• PCjs Machine Utility
