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:
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.
In the wake of my rejection of modern software and complexity, I've stopped using git to manage versioning in Collapse OS because I consider RCS to be sufficient. The commit adding this message is therefore the last I'm adding.
Further improvements of Collapse OS are available on Collapse OS' website as tarballs of the project including RCS metadata. Those tarballs are updated regularly.
Documentation is in text files in
doc/. Begin with
Collapse OS can run on any POSIX platform and builds easily.
/cvm/README.md for instructions.
blk.fs: Collapse OS filesystem's content. See below.
cvm: A C implementation of Collapse OS, allowing it to run natively on any POSIX platform.
arch: collection of makefiles that assemble Collapse OS on different machines.
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.
This file is a big text file containing the "real deal", that is, the contents of Collapse OS' filesystem. That filesystem contains everything that a post-collapse computer would manage, that is, all Forth and assembler source code for the tools it needs to fulfill its goals.
The Collapse OS filesystem is a simple sequence of 1024 bytes blocks. That is
not very workable in the text editor of a modern system.
blk.fs represents an
"unpacked" view of that block system. Each block (16 lines max per block, 64
chars max per line) begins with a marker indicating the block number of the
contents that follow.
Blocks must be in ascending order.
That file can be "packed" to a real blkfs with
/tools/blkpack. A real blkfs
can be "unpacked" to its text file form with
The project unfinished but is progressing well! See Collapse OS' website for more information.
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
