Digital Research DR750

Brand: Digital Research

The Digital Research DR750 is an operating system that was designed for use on personal computers, primarily in the 1970s and 1980s. It was developed by Digital Research, a software company founded by Gary Kildall, the creator of CP/M.The DR750, also known as Concurrent DOS, was an extension of the original CP/M system that added multitasking capabilities to DOS, allowing multiple applications to run simultaneously on a single device. This feature was particularly useful for workstations and servers with multiple users, as it allowed for more efficient resource utilization and reduced wait times for individual tasks.The DR750 was also notable for its support of large disk drives, which provided significantly more storage capacity than the smaller floppy disks of the time. This feature was a critical step in the evolution of personal computing, as it laid the groundwork for the development of modern hard drives and storage technologies.However, Digital Research faced stiff competition from Microsoft's new operating system, MS-DOS, which was compatible with the IBM PC and quickly gained widespread adoption in the industry. As a result, Digital Research's market share declined, and the company ultimately filed for bankruptcy in 1994.Today, the DR750 is primarily of historical interest and is not commonly used in modern computing. However, it remains an important part of the rich legacy of innovation and experimentation that has shaped the evolution of personal computing.
