We sure had fun - as did Jobs and Wozniak (from what I read).

One of Wozniak's claims to fame was that his blue box generated all the tones
digitally.

He became quite good at abusing digital chips for analog purposes -- he did
similarly creative/ugly things when generating (NTSC) color on the Apple II,
adding almost no cost to the design in the process. Such a feat was largely
unmatched for years; it was really only complete graphics ICs like the
Commodore VIC and perhaps the Motorola 6845/6847 that -- eventually, as
volumes increased and prices dropped -- outperformed Woz's approach on a
price/performance basis.
