Claude Code for PowerPC

[](BCOS.md) **World's first: Claude Code running natively on Mac OS X Leopard (2007)**

A full Claude Code-like CLI running on a **Power Mac G5** (PowerPC 970, Mac OS X 10.5 Leopard) with **direct TLS 1.2 connections** to the Anthropic API. No proxy. No relay. No modern machine in the middle.

What This Is

An agentic coding CLI — Claude reads files, writes code, executes shell commands, and searches the filesystem, all running natively on big-endian PowerPC hardware from 2003. The full tool execution loop works, not just chat.

Requirements

• node_ppc — custom QuickJS + mbedTLS runtime for PowerPC Mac OS X
• An Anthropic API key or OAuth credentials (~/.claude/.credentials.json)

Quick Start

# On the G5 (or any machine with node_ppc)
cd ~/node-ppc-scaffold
./node_ppc claude_g5.js

# Non-interactive mode
./node_ppc claude_g5.js -p "List the files in /etc"

# With explicit API key
ANTHROPIC_API_KEY=sk-ant-... ./node_ppc claude_g5.js

Features

Tool Execution

Claude has full access to the local filesystem and shell:

• Read — Read files with line numbers
• Write — Create/overwrite files
• Edit — Surgical string replacement in files
• **Bash
