Oops, i didn't realise it was for actual analogue tapes either, silly me. Just saw tape drive and thought of the one in the building opposite (which i showed). I think they used this machine for some of the Internet2 data challenges, though that might have been the IBM storage Tank (another immense storage system, but HD not tape.) - this place is _full_ of insane tech.
On the one micheal posted, very interesting, especially for my stepfather, who has a big collection of pirate radio stuff from the 70s and 80s he doesn't want to lose. Perhaps a bit pricy though, even with the good £ to $ rates.
Brian, not sure how to help you with the webcam. Its not very picturesque, just black and white grainy images of the backs of tapes, and the odd glimpse of a robotic clamp grabbing them. Attached is a grab, things were moving but obviously that doesn't really come across. Incidentally, this is what is displayed in the top rack of monitors at the control station shown in my last post.
