Description

So, in this stream, we establish a baseline by the common ancestor between the single user versions of DOS, and what would go on to become OS/2 1.x.

Things Done

  • Setup 86Box to emulate a IBM PC XT with two 10 MiB HDDs
  • Installed DOS 2.x to the HDD
  • Setup WordStar as one of the few apps that would run on this version
  • Rebuilt Microsoft DOS 2.x from source code, taking at least an hour (if not longer), and noting differences between the IBM version and the Microsoft version
    • This provides a baseline on how differences go between the two, but there are both technical and user differences between the two
