The Official DR DOS Website

DR DOS® carries forward the legacy of Gary Kildall’s groundbreaking work in operating systems. Originally developed by Digital Research Inc. in 1988, DR DOS was a technically superior alternative to MS‑DOS, offering better performance and compatibility.

This is not just another DOS clone. DR DOS® 9.0 is a faithful clean‑room reimplementation, built from scratch to honor Kildall’s vision while creating a modern, legally unencumbered DOS for the next generation of enthusiasts, developers, and hackers.

What’s Included

DR DOS 9.0 comes with a comprehensive set of commands and utilities:

• Core File Management: CD, COPY, DEL, DIR, MD, MOVE, REN, TYPE, and more
• EDIT Text Editor: Full‑featured editor with colored display, menus, keyboard shortcuts, and clipboard support
• System Utilities: MEM (memory information), VER (version), DATE, CLS, MORE
• Advanced Tools: HEXDUMP for debugging, mouse driver support, REBOOT utility
• Low‑Level Access: PEEK, POKE, and JMP commands for direct memory manipulation and code execution – ideal for learning about operating systems, testing low‑level code, and DOS development

Who Is This For?

DR DOS 9.0 is ideal for:

• DOS enthusiasts and retro‑computing hobbyists
• Developers interested in operating system development and low‑level programming
• Educational purposes and learning about operating systems
• Testing classic DOS software compatibility
• Embedded systems requiring a minimal DOS environment
• Anyone curious about the heritage of PC operating systems
