My uncle had a business with an IBM minicomputer: a System/36. It was the size of a large freezer. It also used 8" floppies! It took a "magazine" of 10x 8" floppies and could swap between them. It looked like the system in the top photo here: https://en.wikipedia.org/wiki/IBM_System/36

Yeah, that's extremely cool. The wiki page had me at:

The Datamaster was IBM's only 8-bit microcomputer and one of the few to use the EBCDIC encoding.

The machine came with a few new boxes of 8" still in the cellophane.
