   No, I don't care about the high parts.

   Ok, great.   
      
   It's more of a "starter system".   
      
   With this, you will have the tools available to reconstruct   
   the world, including what you call a "serious OS".   
      
   Without having to zap machine code.

   MSDOS was called an OS for a long time (decades).   
      
   If you have a definition different from Microsoft, fine,   
   neither MSDOS nor PDOS are operating systems.   
      
   My definition is - manage memory, manage disk and   
   launch executables and provide an API for those   
   executables.   
      
   PDOS does all that.
