Microsoft MS-DOS 2.11 and 1.25 [Zenith Z100 PC]
Released in 1985 by Microsoft/Zenith
For Zenith Z-100 PC Series.

This is Zenith's OEM of MS-DOS 2.11 for the Zenith Z-100 PC Series
computers. It also bundles an MS-DOS 1.25 disk for extra
compatibility. These disks contain extra customizations and tools
specifically for the Z-100 PC series.

Important: The term "Z-100 PC" refers to Zenith's IBM PC compatible
computers, such as the Z-150, Z-160, etc. However this confusingly
excludes the original Z-100/Z-110/Z-120 models that were not IBM PC
compatible. Those ran a different port of DOS, sometimes referred to
as "Z-DOS".

This set contains three 320K 5.25" distribution disks:

I: MS "TM"-DOS VERSION 2 FOR THE Z-100 PC (disk 1)
II: MS "TM'-DOS VERSION 2 FOR THE Z-100 PC (disk 2)
III: MS "TM"-DOS VERSION 1.25 FOR THE Z-100 PC
