Re: New product: RetroConnector keyboard shields



Re: any key down, not entirely certain, but mine should work that way. It does everything through making the same electrical connections the physical //e keyboard would (grounding some pins, 5v to others, etc) through multiplexing switches. It gets a key down from the USB keyboard, and keeps the pins switched together until it gets a key up.

Nishida's probably works in a similar way, but I could never get any information from him about his design.
