Could confuse everyone even more by getting hold of some ancient huge 8" floppy disks. I remember going to 6th form college in 1990 and my form tutor had some pretty ancient IBM PCs in this room (even by 1990 standards) and they had these huge 8" floppy disk drives. The things were massive and I hadn't seen that format before. It was almost like inserting a cased record into the drives.
