  Was not expecting the fractal viewer (in disk B/apps)

  The graphical operating system that could have been for the IBM XT.

  A MacOS-like desktop for the Intel 8086, written entirely in real-mode assembly (with Claude). Verified to run on real hardware, with FAT12/16 support, ported apps, games, Sound Blaster support and upcoming Hard Drive support.

    Well there was GeoWorks (which AOL used the GUI of to their advantage):

    Just discovered the videos (https://www.youtube.com/@NostalgiaPCTV) ...and the source code on github reads like a book.

    Amazing.

      Apple might sue you though, like they did DRI :-)

  This rewrites what-could-have-been history a bit... better get my IBM XT/286 out of storage! Is this for real?

  Fun little toy. Wonder how much in tokens went into it.

  If it were available back then, Microsoft may be a small shop today or may have gone the way of Lotus.

  It's funny how virtually everyone on HN is using AI to write code and simultaneously dismisses all interesting new software as written by AI.
