If I remember right, the seek signal was a data clock and the seek direction signal was the out data. I don't remember the in data. The other signals were ignored. You sent command blocks to the tape drive by sending a series of seek requests that caused the command block to be encoded on the seek/seek direction pins. The you would toggle the seek pin and read the input pin to read the response.
