I went through two periods as a company’s IT director where we transferred important data from older media to what would be our newest media, to be sure, in spite of time, we could still get to it if needed.

I did it at home, a number of times, with my PCs, as older data storage media was becaming obsolete.

Just for show, I still have a few 5 1/2 inch floppy disks on an office bookshelf.

So do I, along with the 8" variety. ;-D

I also have a collection of fuse-link, UV-PROM, and EEPROM memory devices.

I wish I had a set of AM2900 bit-slice elements.

...floppy disks...

You may already know this, but the 8-inch floppy disk was developed to provide instruction microcode for the IBM Sys/370. Right after power up, that computer would read from an 8-inch floppy just behind the front panel in order to retrieve the instruction set's microcode. It did not just emulate a 1400 Series machine, it became a 1400 series machine when that floppy was in place. Normally, the 360/370 instruction set floppy was in there.

The Xebec Company licensed the technology from IBM and then made the first commercially available floppy drive system. Those were initially targeted for PDP-8 and PDP-11 computers. Digital Equipment Corporation didn't let that stand for long.
