Virgil Dupras 83b314c450 zasm: lower RAM requirements 
I've tested RAM usage when self-assembling and there weren't as high
as I thought. zasm's defaults now use less than 0x1800 bytes of RAM,
making it possible, theoretically for now, for a Sega Master System
to assemble Collapse OS from within itself.

Collapse OS

Bootstrap post-collapse technology

Collapse OS is a z80 kernel and a collection of programs, tools and documentation that allows you to assemble an OS that, when completed, will be able 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. 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.

Organisation of this repository

  • kernel: Pieces of code to be assembled by the user into a kernel.
  • apps: Pieces of code to be assembled into "userspace" application.
  • recipes: collection of recipes that assemble parts together on a specific machine.
  • doc: User guide for when you've successfully installed Collapse OS.
  • tools: Tools for working with Collapse OS from "modern" environments. Mostly development tools, but also contains emulated zasm, which is necessary to build Collapse OS from a non-Collapse OS machine.

Each folder has a README with more details.

Status

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