Not a display thing, but this was in 1987...
Yes, 1987, when 3.5" floppies were just becoming a thing.
I was a student working in an actual programming job for the summer, and the company had some sort of big contract with IBM, and we had all sorts of interesting toys to play with:
* A "bar" plotter - it took paper of the A1 or A0 sort of size (actually a size the Americans call "D"). Much fun.
* Personal System/2 machines, model 50 and 60.
* 3270 terminal emulator cards for the PS/2 machines
* other things that aren't important here.
Anyway, one of the saleswomen brought me a 3.5" floppy for a copy of the software I was working on. Those floppies had two different kinds of labels - small ones that stuck only on the front, and large ones that wrapped around the top onto the back.
And of course she, not being very familiar with what was, of course, a *new* thing in PCs, had stuck a large label entirely on the front, covering part of the metal shutter.
I'm embarrassed to have to admit that it took me several attempts before I realised *why* the disk wouldn't go into the drive. (OK, it went most of the way in, but stopped about half an inch before it was fully in.)
