Developing a windowed OS for a homebrew Am29000 computer

Once upon a time in the mysterious lands of Mexico, starting in Fall 1996 and through Spring 1997, I coded a windowed operating system in 32-bit machine code, fit it into a floppy, and jumped in excitement as it boot up.

Of course, I knew it was a great thing because you couldn't boot Windows 3.1 or GEM from a floppy disk, but I was very far from knowing how so cool it was. Unfortunately, not a thing I could give away for everyone to see, as it was written for a homebrew computer based on the Am29000 processor.

Let's go back to my memories, some notes, and the ride of discovering again what I forgotten.

Oscar Toledo Gutierrez

Trying to summarise this absolute gem of an article and all of the amazing effort and skill involved would be a huge disservice to Oscar Toledo Gutierrez. I enjoyed this so much. Be sure to try out his custom emulator of a custom computer to run his custom operating system.
