## What it is
MOROS is a text-based hobby operating system written in Rust for x86-64 BIOS computers, inspired by Unix, Plan 9, and DOS. It includes a custom filesystem, shell, Lisp interpreter, text editor, network stack, and games, and runs natively or in emulators like QEMU.

## Use cases
- run a minimal rust-written operating system in qemu
- learn operating system development from a real hobby kernel
- explore a unix-like command line environment on old x86-64 hardware
- experiment with a custom filesystem and syscall interface
- play doom and other games inside a hobby os
- write scripts with a lisp interpreter in an os userspace
- test network protocols like dhcp and http in a toy kernel

## When to choose
- you want a small, readable rust codebase for learning osdev
- you need a text-based os that runs on legacy x86-64 bios machines or emulators
- you want a self-contained system with shell, editor, lisp, and networking included

## When to avoid
- you need a production-grade os with hardware drivers, usb support, or security hardening
- you require uefi boot or modern hardware support
- you want a general-purpose desktop or server operating system

## Facets
- artifact type: application
- maturity: active
- function: interpreter, cli, networking, file-system, game, graphics
- domain: operating-systems, developer-tools, networking
- platform: cpp, rust, cross-platform
- tags: operating-system, osdev, hobby-os, x86-64, kernel, shell, lisp, qemu, bios, text-based, command-line
