Bootstrap post-collapse technology

Winter is coming and Collapse OS aims to soften the
blow. It is a Forth (why Forth?) operating system and
a collection of tools and documentation with a single purpose: preserve the
ability to program microcontrollers through civilizational
collapse. It is designed to:

1. Run on minimal and improvised machines.
2. Interface through improvised means (serial, keyboard, display).
3. Edit text and binary contents.
4. Compile assembler source 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.

The Collapse OS project is completed!
It can be downloaded here. Highlights:

• Runs on Z80, 8086, 6809 and 6502 machines with very little resources.
  See hardware support list.
• Can assemble Z80, AVR, 8086, 6809 and 6502 binaries.
• Can disassemble 6502 and 6809.
• Can emulate 6502 and 6809 (in Collapse OS itself!).
• Can program AVR microcontrollers.
• Has a command line text editor similar to Forth’s traditional editor as
  well as a visual text editor inspired by UNIX’ VI.
• Has a visual binary edi
