(Yes, the ending dash is supposed to be there.)

A Blue Box design that emulates classic Blue Box tones, plus 12 other historical tone modes. It produces 12 tone signalling systems used by phone phreaks to hack other more exotic system in the US and overseas, including early pre-cellular mobile telephone systems from the 50s, 60s, and 70s, including the classic bluebox and the DTMF suite. 12 memories of up to 32 tone sequences each. Sine waves from PWM.

Maybe make myself a con badge out of it?
