Very True, and one thing people forget, we need to keep the ability to read these old devices.

I was a operator (now admin) on a few minis in the early 80s that had these drives. The drive pack on the ones we had were removable and we used 256MB packs.

We would backup data from one drive to another on third shift, at the same time to reel tapes. The reel tapes back then where used for long term backup off site, the drives for short term on site. But who knows how many of these packs are out there just sitting around waiting to be read :)
