OK, yeah, the drives I have look nothing like those. Those drives are very old vacuum column type drives - mainframe type. There would be a separate tape controller unit box that controls those - and is again the size of the drive. It is going to be quite difficult to find one. The drives I have are smaller ones, minicomputer type. Integrated interface boards, smaller. They still use the vacuum column air bearing type setup, but it's much smaller and hidden from view. They're rack mount units, the reels are one above the other, and are mostly hidden behind a plastic cover with a fairly small window - just enough to see the supply reel turning.
