I've always wanted a full-sized 6250 BPI tape drive just to spin back and forth here in my office. The computer center in my old agency used to have banks of them with reels spinning as they fed the two big siamesed IBM 4381 mainframes. I used to write JCL for the meteorological modeling programs we ran in them, and the world's weather data arrived on those tapes via either FedEx or UPS every 6 hours, forcing us to hang them and strip the data off for the "live" met models.
