From Walter Isaacson's biography:

Woz and Jobs got their first big break from selling physical copies of the 'Blue Box', a device which allowed you to place long-distance phone calls through intelligently breaking AT&T's phone routing network. In today's 'wire fraud' day and age, this 100% would have been illegal -- so note that these two people made today's most valuable company!

Relatively speaking, printing a photo ID or $2 bills is nothing. It is the hacker spirit (notice we are on a site called hacker news!).
