86-DOS

86-DOS, or "86 Disk Operating System," was an early computer operating system developed in the early 1980s for Intel's 8086 microprocessor-based PCs. It provided basic functions like managing files, running programs, and interacting with hardware, enabling users to operate their computers more efficiently. Microsoft purchased and adapted 86-DOS (renaming it MS-DOS) to become the foundation for their hugely successful line of PC operating systems. Essentially, 86-DOS was a pioneering software that helped make personal computers more accessible and functional for both businesses and individuals.
