ACI (Apple Cassette Interface) PCB for the Apple-1 | Gold Plated

Load data and software into your Apple-1 with this ACI (Apple Cassette Interface) board. The PCB comes unpopulated but, once populated, can simply be inserted into an Apple-1 expansion port and be used as data input and output for the computer via audio signals. The audio source can be an actual cassette player or any modern computer.
