Collapse OS

Bootstrap post-collapse technology

Winter is coming and Collapse OS aims to soften the blow. It is a z80 kernel and a collection of programs, tools and documentation that allows you to assemble an OS that can:

  1. Run on minimal and improvised machines.
  2. Interface through improvised means (serial, keyboard, display).
  3. Edit text files.
  4. Compile assembler source files for a wide range of MCUs and CPUs.
  5. Read and write from a wide range of storage devices.
  6. Replicate itself.

Additionally, the goal of this project is to be as self-contained as possible. With a copy of this project, a capable and creative person should be able to manage to build and install Collapse OS without external resources (i.e. internet) on a machine of her design, built from scavenged parts with low-tech tools.


The project lives on github and is progressing well! Highlights:

If you have further questions about the project, a big discussion about it occurred on Reddit and I answered a lot of questions there.

There was also a nice conversation on Hacker News about Collapse OS, but I didn't participate because I don't have a HN account. Also, this community doesn't seem collapse-aware so the idea of participation into this discussion seemed tedious to me. But the user "yellowapple" did a good job of answering many questions in a way that is similar to what I would have.
