MS-DOS v1.25, v2.0, v4.0 Source Code Description

What is the project about?

The project is a repository containing the original source code and compiled binaries for MS-DOS versions 1.25 and 2.0, along with the source code for MS-DOS 4.00. It's a historical archive of a foundational operating system for early PCs.

What problem does it solve?

The project itself doesn't "solve" a modern problem. Its primary purpose is to provide historical context and make the source code easily accessible for research, education, and experimentation. It allows people to study the inner workings of early operating systems.

What are the features of the project?

  • Provides the original source code for MS-DOS v1.25, v2.0, and v4.00.
  • Includes compiled binaries for MS-DOS v1.25 and v2.0.
  • Is licensed under the MIT License, allowing for free use and modification.
  • Is intended for historical reference and educational purposes.

What are the technologies used in the project?

  • Assembly language (primarily, as MS-DOS was written in assembly for the Intel 8086/8088 processors).

What are the benefits of the project?

  • Educational: Provides a valuable resource for learning about operating system design and the history of computing.
  • Research: Allows researchers to analyze the evolution of operating systems.
  • Accessibility: Makes the source code readily available to a wider audience.
  • Experimentation: Enables enthusiasts to explore and modify the code (in forks).

What are the use cases of the project?

  • Studying operating system fundamentals.
  • Historical research into early PC software.
  • Educational projects and coursework.
  • Personal exploration and experimentation by software enthusiasts.
  • Understanding the evolution of software development practices.
