From the project

Test keyboard for the TK2000 computer

Any use of this project is under your own responsibility. You will be responsible of checking the correct construction and functionality of your board. By using this project You will agree that I cannot be held responsible if it will destroy any of your devices, damage your computer, burn down your house or whatever.

I recently built for myself a TK2000 clone, but I don't have a keyboard to use it so, before making an expensive mechanical one, I decided to test the design making one with some cheap SMD switches I had around.
