I still have a 1541 C-64 disk drive with modified hardware that let it copy anything back in the day. Ordered it mail order, just open up the drive and plug it in. I got boxes of 'backup' games, I wonder how many floppies could be salvagible after 30 years? 1541 copy protection was so bad, the knocking would knock the drives out of alignment occasionally, and you'd have to mail them out to get repaired.
