Notes
This keyboard was featured in my Exploring the elusive IBM 4683 Matrix Keyboard P/N 76X0100 article, which was likely one of the first full teardowns of the keyboard published. I received the keyboard in like-new condition; it was originally NOS but previous owner u/drake9800 who had it for only a short time opened the keyboard to figure out what it was since no concrete background material on the keyboard existed before.
