All I ever dialed from my Commodore 64 (the SID chip generated bluebox tones) in 1993 was the They Might Be Giants band dial-a-song, which played a new tune eve

  Are you sure these weren't just DTMF tones? http://en.wikipedia.org/wiki/Dual-tone_multi-frequency http://en.wikipedia.org/wiki/Dual-tone_multi-frequency By 1993, they had closed the loophole that allowed audio signals to direct the phone switching network. With your Commodore 64, you were probably playing DTMF tones, which control touch-tone dialing. With a blue box, rather than dialing a phone number, Woz was actually changing the way his call was routed. He was controlling the switching network itself, routing his call manually across the globe. With DTMF, you are just dialing a phone number the same way you do with your finger.

    It could be, but that is not the whole story. Plenty of countries were 'late' in wising up to this and took a lot longer to adapt to out of band signalling. So, depending on the age of the network you're on there is some chance that even today you could use tricks like these. 1993 is perfectly believable to me, depending on the location of the person making the claim. The tone to reset a trunk was 2.6 KHz, the reason why '2600' is still a term with notstalgia attached to it for very early hackers.
