Qaz Personal Terminal

A modern homage to the TRS-80 Model 100 — reimagined as a 33-key portable hacking terminal powered by the Raspberry Pi Compute Module 4.

---

🔧 What is this?

The Qaz Personal Terminal is a minimalist, portable hacking machine inspired by retro terminals like the Tandy Model 100. It's built around the Raspberry Pi CM4, exposing full GPIO access, USB, Wi-Fi, Bluetooth, and a compact 33-key mechanical keyboard layout based on the Qaz form factor.

Perfect for:

• On-the-go terminal work
• Hardware hacking
• Tethered field ops
• Writing code in a ditch (probably)
