# Collapse OS

## Moved to Sourcehut

The project has been moved to <https://sr.ht/~vdupras/collapseos/>. See
[issue #127](https://github.com/hsoft/collapseos/issues/127) for details.

If it hasn't been already, this repo will end up being put in Archived mode.
Some issues opened on Github open very interesting discussions. Do not
hesitate to begin a thread referring to a Github issue on the mailing list
associated to the project on Sourcehut.

Until the project is archived, know that any PR opened here will be ignored.
Please submit a patch on the mailing list.

## Presentation

*Bootstrap post-collapse technology*

Collapse OS is a Forth operating system and a collection of tools and
documentation with a single purpose: preserve the ability to program micro-
controllers through civilizational collapse.

It it designed to:

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. Assemble itself and deploy to another machine.

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.

## Getting started

Usage documentation is in-system, so access to documentation requires you to
run Collapse OS. Fortunately, doing so in an emulator is easy.

See `/emul/README.md` for getting an emulated system running.

Then, run `0 LIST` for an introduction, follow instructions from there.

## Organisation of this repository

* `blk`: Collapse OS filesystem's content. That's actually where Collapse OS'
         source code is located. Everything else is peripheral.
* `recipes`: collection of recipes that assemble Collapse OS on a specific
             machine.
* `tools`: Tools for working with Collapse OS from "modern" environments. For
           example, tools for facilitating data upload to a Collapse OS machine
           through a serial port.
* `emul`: Tools for running Collapse OS in an emulated environment.
* `tests`: Automated test suite for the whole project.

## Status

The project unfinished but is progressing well! See [Collapse OS' website][web]
for more information.

## Looking for the assembler version?

The Forth-based Collapse OS is the second incarnation of the concept. The first
one was entirely written in z80 assembly. If you're interested in that
incarnation, checkout the `z80asm` branch.

## Discussion

ideas that may develop around it refer to [r/collapseos][discussion]

I also stick around on IRC (#collapseos on freenode).
