A Macintosh floppy disk signed by Apple co-founder Steve Jobs sold at auction for many thousands of dollars more than expected.

This is terribly ironic considering Jobs helped kill the floppy disk by pulling disk readers out of Apple laptops and desktops. Now his signature resulted in one of the most expensive disks ever.

Jason Scott is an archivist and the enthusiasm for what he curates is the kind ascribed to 15th-century manuscripts or Jamestown colony artifacts – not software on obsolete floppy disks written for a 40-year-old computer system.

Scott is out to collect any original or copied software disks for the Apple II as if a language is in danger of dying with the people who speak it or possess some record of its existence.

If you’ve ever had the pleasure of inserting an old floppy of Jordan Mechner’s classic beat-em-up Karateka into a vintage Apple II, you already know it’s one of the most timelessly classic video ames ever made.

Ever tried inserting the floppy disk upside down, though? If you’re one of the few people who have, whether by accident or design, you’ve experienced one of the greatest and funniest Apple easter eggs of all time: the whole game played upside down.
