I remember seeing a few of these back in the day ... https://en.wikipedia.org/wiki/2600%3A_The_Hacker_Quarterly --- "The magazine's name comes from the phreaker discovery in the 1960s that the transmission of a 2600 hertz tone – which could be produced perfectly with a plastic toy whistle given away free with Cap'n Crunch cereal, discovered by friends of John Draper – over a long-distance trunk connection gained access to operator mode, and allowed the user to explore aspects of the telephone system that were not otherwise accessible." #security #2600magazine #2600 #hacking
