DEC TU-58 Drives

I finally got back to working on my PDP-11/44, and finished cleaning it up yesterday. So now I'm ready to start testing stuff. Which brings me to my question, I went ahead and plugged the TU-58 drives in to see if they would give any indication of life. Not a thing. Do they have to be plugged into the line (serial I think), or have a tape in them before they will show any signs of life? Zane | Zane H.
