promising high school students. GE isn't what it was then, and one of the
few things that did happen was touch tone dialing. Kennedy opened the fair
with a TT phone and there was a booth where you could see how much faster
it was than a rotary dial. Of course Ma Bell owned the whole shebang.

Wow."Touch-tone" WAS do-able ...But you had to pay for it. A friend and I hacked relays into our modems'
phone connection, activated by the DTR line. A suitable driver enabled
us to pulse dial at whatever speed we wanted. Maybe it was just the COs
updating their equipment for Touch-Tone, but we found that we could pulse
dial at 20 pps. It was almost as fast as Touch-Tone.
They are trying to do that with big drone like fly-taxis, automated :-)But STILL want my flying car !!!I'm not so sure about that. The way people are driving these days,
the last thing I want to see is for flying to gain mass appeal.

Bell/ATT facility. It was PACKED with row after row after
row of relay-operated dialer machines. Physically connected
one physical line with others. SO cool to watch ! Ca-chunk,
ca-chunk, ca-chunk the discs would go around in order to
connect A with B - layer after layer. Straight-up wired
contacts back then, no software. Electro-mechanical magic !
