This is a quick demonstration of how to connect a Raspberry Pi to the built-in keyboard of a vintage Apple II (the Apple //c) with the help of the RetroConnector Shield.
The RetroConnector is a shield for the PJRC Teensy++ Arduino clone that acts as a USB HID device, translating keystrokes on the //c keyboard into something a modern computer (PC, Mac, Raspberry Pi) can understand.
