I remember seeing these back in the Seventies. My father was computer operations manager for IU Bloomington and spent more time there than a kid would like.
At the time the machine room was on Seventeenth St and as you walked in and up an 18 inch or so tall ramp the printers were on the left and the disc drives were against the wall on the right. The tape drives were in two rows of ten on the left after you walked in maybe 30 feet. The CPU was on the far side of the room from the entrance. I remember an IBM 360 being in place but there were others, later. A lot of the time the operators had panels open, or ajar, due to heat issues. Punch card sorters were on the left wall behind the printers
Most of the times that I was there the machine was down for one reason or another, usually a thunderstorm, but sometimes they would be waiting on an IBM engineer to get there and fix it. One time the problem was multiple people out sick so my dad had to help out due to a big job that had to be done that weekend. I was maybe 12 and remember hanging tapes on the tape drives. Had to read the screen to see which one was needed, find it on the rack, remove the outer cover on the tape as you walked to the drive which would already be rewound and open. Stretch to reach the tape release and pull the tape off, slide the fresh tape onto the spindle making sure to leave a bit of tape hanging free. I wasn't tall enough to reach the control buttons on the top so I had to use the alternate method of briefly squeezing the bottom seal. The glass cover would glide up and you'd hear a brief hiss as the unit pulled a vacuum, and sucked the tape down into the channels, past the read head, and up to the take up reel. In movies you see these types of tape drives spinning but they hardly ever did this. Usually they'd twitch back and forth, often independently.
My dad did change one of the disc drives that time, way too heavy for a 12yo to pull out of the unit without doing something like kneeling on top of the unit and they wouldn't have liked that. It was pretty much just twist and lift, reverse to insert fresh one.
