MS-DOS 1.25

MS-DOS 1.0 was released August, 1981 while 1.25 was released a year later.

1.X was very limited to what it could do. It could start .COM, and .EXE applications, and it could also process batch files (.BAT).

1.X worked with 160KB floppy images, but it did support folders, (all had to be within the system)

The only commands you could do in 1.X was:

DIR, TYPE, COPY, ERASE, RENAME, PAUSE, REM,

DOS 1.X did not support pipes, redirection, or device drivers. The API was also very limited as well.
