I happened to be going through some boxes in the garage tonight and found an old manual for a Commodore floppy drive. It kind-of explains a lot about how different a personal computer was back then. The back of the manual has the schematic for the drive! My Commodore 64 Programmer's Reference Guide also came with a fold-out schematic and I remember the first time I built my own Pentium the motherboard came with instructions for all the pin sets. But we've lost that access to our devices.
