Details

Apple II Vintage Parallel Printer Interface is a very rare original apple card. It does not include the cable. It was one of the first interface cards made for the Apple II and was released by Apple in 1977. The card retailed for $180. Wozniak wrote the firmware ROM, and managed to make it fit entirely in only 256 bytes. As a parallel device, it used eight wires to connect the computer with a printer, one line for each data bit in a byte. Various parallel devices also used one or more extra wires as control lines, including a ?busy? line (so the receiving device could tell the sending device to stop until it was ready for more), and a ?ready? line (so the receiving device could tell the sending device to resume transmission).
