This project enables an existing Amiga 600 Keyboard to operate as a USB Keyboard with the Case LEDs to indicate power/scroll lock and numlock.
The Amiga 600 QMK_Firmware image has been designed to work with this PCB a precompiled version can be found in this projects qmk_firmware directory.

This is a two layer through hole design. It was made using Easy EDA with the associated PCB source in the projects EasyEDA Source directory. I used their affiliate to manufacture the PCBs and was happy with the outcome and the cost, however this is not essential. Easy EDA supports generating Gerber files that can be used by other vendors, or if you have the materials you can produce the PCB yourself. Gerber files are in the projects Gerber Directory

Assembled Prototype PCB connected to a Keyboard
While this PCB does not require advanced soldering skills, it may be best to work with an experienced friend or watch some youtube videos on build techniques.
The Teensy requires programming before use and can be programmed in circuit. If you haven't worked with one before, https://www.pjrc.com/teensy/first_use.html is probably a good place to start - followed by using the teensy loader to load the keyboard hex code.
Testing should be relatively straight forward - open a text editor and start typing, alternatively there is a humorous though effective web based tester at http://www.keyboardtester.com/
