This vintage Microsoft MS-DOS Operating System Version 4.01 boxed manual set includes three original manuals:
• Microsoft GW-BASIC User’s Guide and User’s Reference
• Microsoft MS-DOS User’s Guide and User’s Reference
• Microsoft MS-DOS Shell User’s Guide

These are original late-1980s manuals (© 1986–1987), published for systems compatible with IBM Personal Computers. A great set for retro PC collectors, software historians, and restorers of early DOS-based machines.

• Outer cardboard box shows heavy wear, tears, and crushed edges

• Manuals are clean overall, showing only light handling marks

• No writing or major damage visible in the interior pages

• No disks included with this set

• Authentic Microsoft manuals from the MS-DOS 4.x era

• Clean typography and layout typical of mid-80s Microsoft documentation

• GW-BASIC conversion appendix and programming details

• Shell user guide included, which is often missing in partial sets

A solid, display-worthy piece of PC history despite the box wear.
