IBM PC-DOS 1.00
The release of the command line DOS, or Disk Operating System, coincided with the birth of personal computing and the beginning of Microsoft's rise in the world of PCs.
The OS, a rebranded clone of the CP/M operating system, was provided by Microsoft to IBM for its first PC, which released in 1981. However Microsoft retained ownership of MS-DOS, which went on to run on the myriad IBM PC clones created by rival companies.
This emulator runs IBM PC-DOS 1.00 on an IBM PC (Model 5150) with a monochrome display.
