MS-DOS 1.25

There was no MS-DOS 1.25 *per se*. Instead, there were assorted OEM releases of MS-DOS based on version 1.25.
Here, we have two such releases:
* MS-DOS v1.25 (Compaq v1.11)
* MS-DOS v1.25 (Compaq v1.12)
Directory listings of each of these 360Kb diskettes are provided [below](#directory-listings).
