Virgil Dupras cdd0b64570 Modify userspace .org and RAMSTART expectations 
Instead of expecting a `USER_CODE` symbol to be set, we expect `.org` to be
set in all userspace glue code. This gives us more flexibility with regards to
how we manage that.

Moreover, instead of making `USER_RAMSTART` mandatory, we make it default to
the end of the binary, which is adequate in a majority of cases.

Will be useful for my upcoming mega-commit... :)

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.

See it in action

Michael Schierl has put together a set of emulators running in the browser that run Collapse OS in different contexts.

Using those while following along with the User Guide is your quickest path to giving Collapse OS a try.

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.

Discussion

For a general discussion of Collapse OS and the ecosystem of technologies and ideas that may develop around it refer to r/collapseos

A more traditional mailing list and IRC (#collapseos on freenode) channels are also maintained.
