This is the 1982 IBM’s DOS version 1.1 for the Personal Computer in canvas covered 3 ring binder (1st Edition).  This version supported the new double sided 5.25” diskettes (320KB) while prior version 1.0 was for only one floppy disk.  These DOS operating systems were from Microsoft whom some say they stole the operating system from Seattle Computer Products (Although Microsoft paid Seattle, a soap opera story goes with the purchase).  This DOS 1.1 looks like new and never used.  Reference card is also included.  Cover has a few minor marks, but displays well.  It is a beautiful piece of history from 29+ years ago.
