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

### Option 2: QuickJS
QuickJS provides modern JavaScript on Tiger:
```bash
cd quickjs-2024-01-13
make -f Makefile.ppc
./qjs claude.js
```

## Building QuickJS for Tiger (G4)

```bash
# 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 970 with AltiVec, and Leopard (10.5) ships a newer
userland than Tiger (Python 2.5, optional modern GCC). The G5 variant tunes for
the 970 and targets Leopard:

```bash
# On the G5 (Leopard 10.5), system GCC 4.0.1 — the default, validated build
cd quickjs-2024-01-13
make -f Makefile.ppc.g5            # -mcpu=970 -maltivec, Leopard 10.5 min
./qjs claude.js

# Native 64-bit ppc64 (the G5 is 64-bit; the G4 is not):
make -f Makefile.ppc.g5 ABI=64

# With a modern toolchain (e.g. /usr/local/gcc-10) for faster codegen:
make -f Makefile.ppc.g5 CC=/usr/local/gcc-10/bin/gcc GCC10=1
```

Variant files: `Makefile.ppc.g5`, `leopard_compat.h` (the Leopard sibling of
`tiger_compat.h` — keeps the `clock_gettime` shim), and `repl_stub.c` (empty
REPL/qjscalc blobs so `qjs` links for script use).

## Hardware Tested

| Machine | CPU | OS | RAM | Status |
|---------|-----|-----|-----|--------|
| Power Mac G4 | Dual 1.25 GHz | Tiger 10.4 | 2GB | Working |
| PowerBook G4 | 1.67 GHz | Tiger 10.4 | 2GB | Working |
| Power Mac G5 | Dual 2.0 GHz | Leopard 10.5.9 | 6GB | **Working** — G5 variant build + run verified on hardware |
