Claude Code for PowerPC G4 (Mac OS X Tiger)

**Running Claude Code on 20-year-old Macs!**

This is an experimental port of Claude Code concepts for Mac OS X Tiger (10.4) and Leopard (10.5) on PowerPC G4/G5 processors.

What's Included

File	Description
claude_code_g4.py	Python Claude API client for Tiger
claude.js / claude_code.js	QuickJS-based Claude implementation
claude_proxy*.py	HTTP proxy helpers for old TLS
quickjs-2024-01-13/	QuickJS with Tiger/Leopard patches

The Challenge

Tiger/Leopard have several limitations:

• Python 2.3 (no modern SSL)
• Old OpenSSL (TLS 1.0 only)
• No Node.js (requires 64-bit or modern libc)

Solutions

Option 1: Python with TLS Proxy

Use a modern machine to proxy HTTPS:

# On Tiger
python claude_code_g4.py --proxy http://modern-machine:8080

Option 2: QuickJS

QuickJS provides modern JavaScript on Tiger:

cd quickjs-2024-01-13
make -f Makefile.ppc
./qjs claude.js

Building QuickJS for Tiger (G4)

# On Tiger with Xcode 2.5
cd quickjs-2024-01-13
make -f Makefile.ppc CC="gcc -mcpu=7450" CFLAGS="-O2"

Building QuickJS for Leopard (G5) — the G5 variant

The G5 is a 64-bit PowerPC
