Now this is one amazing Goodwill find: A vintage pop-up book designed to teach burgeoning nerds about the wonders of the modern computer. Floppy disks, ASCII, and the dot-matrix printer. Oh my.
Some of this stuff is amazing, like an ASCII and binary decoder, and the hilarious message on the dot-matrix printer:
Now that we've met, I'm ready to work—and play—with you. See you soon! Goodbye.
Computers used to be so adorable (and polite!). [JonathanRyan]
