Take a look at (and listen to) my various parallel IEEE-488 Commodore floppy disk drives, including the 4040, 8050, 2031LP, and SFD 1001, hooked up to my PET 4032 computer. We'll open a brand new box of disks, format them, and learn about the various capacities and compatibilities of the drives along with many related diversions.
