I had to deal with the next generation upgrade
Lo and behold, I was the PFY...
And the shiny new tech at the time was the IBM PS/2 (this story is lost in the veil of times, reminiscences from another millenium)
Nevertheless, the IT Director secretary was the first one to get one on our floor, and I was called because she couldn't use the floppy.
Like, it was impossible to insert a new one.
So I get there (with pliers, not my first rodeo) and see to the side a box of 5"1/4.
She was in the process of transferring her files to the new system. And that's good.
She was using the 5"1/4 floppy and put them into the 3"1/2 BY FOLDING THE DISKS IN 4 AND CRAMMING THEM IN THE READER.
Also she complained that, for some reason, it didn't seem to work....
And this is how I first learned to explain PEBKAC to a very understanding IT Manager and his (close to retirement) secretary...
