DR DOS

DR DOS (Digital Research DOS) is an early computer operating system developed in the 1980s, designed to manage files and hardware for personal computers. It provides the essential functions needed for a computer to start, run software, and save data, similar to what more familiar systems like MS-DOS do. Known for its stability and advanced features, DR DOS was often used as an alternative to other DOS versions. It helped lay the groundwork for modern operating systems, offering users a way to interact with their computers efficiently before the dominance of graphical interfaces.
