Yep, I should have followed my instinct and assumed otherwise. Wired‘s wording was this: “…TRS-80, one of the first affordable personal computers and one of the first devices RadioShack ever produced. … John Draper, the phone phreaker known as “Captain Crunch,” hacked his way into free long-distance calls using a Touch Tone dialer he bought from RadioShack.

Woz bought one too, and he says it cost him a fortune. He used it for the now-infamous Blue Box”

To me, this said that the expensive thing (the computer) is what they used for the bluebox. But that’s not a very logical choice to the average nerd (unless you’re a nerd that has just unboxed that expensive $599 machine and really want to prove a point). So I’ll bet you’re right: I’d place my money on this having been a modded TouchTone keypad, which — if nothing else — could be salvaged from a $54.95 RadioShack phone in 1979. And such a keypad fits in that museum photo. Thanks for pointing this out.
