This is an Apple 1 to Apple II Keyboard Connector. Comes with both cables. I wanted a way to easily connect my Apple 1 Mimeo Reproduction unit to an Apple II Keyboard. I didn’t want to cut traces or alter any wiring. I consulted with Apple 1 expert, Mike Willegal, known for the Apple 1 Mimeo Board. Mike designed the circuit layout and I had the boards made. It works great. It includes a clear screen button, which isn’t available on a standard Apple II keyboard. Since I found it useful, I thought that others might want one. I offer them with both cables, ready to use. The customer may specify the cable length they want, and I will be happy to make them to order.
