DR-DOS3.40 1.0
DR-DOS was developed by Digital Research and was originally used as an operating system on PCs. The full name of DR-DOS is Digital Research-Disk Operating System. Mainly supports IBM PC compatible machines. Starting with Windows 3.0 in 1990, when PCs were widely used, DOS systems were gradually replaced. By the time Windows 95 was fully adopted in 1995, the influence of DOS had waned, and DR-DOS was rapidly declining in the desktop market. DR-DOS has a small number of applications in single-tasking embedded devices, and a very small number of DOS enthusiasts are still studying or using DR-DOS. In 2004, DR-DOS version 8.0 was released, with only minor changes in functionality, supporting FAT32 and large hard drives, and was later withdrawn from the market for copyright reasons.
