When I was a kid I got my first taste of that situation. 1969, Cedar Falls, 
Iowa. A friend of mine had a pair of tabletop intercoms at his house. Sorry 
I don't remember what make or anything. ISTR they were sort of blue-green in 
color, speaker and key on the front panel, metal chassis; seemed very cool 
to me. Plugged my end in wrong the first time and really got bit when I 
grabbed the key to send.

He knew you had to flip the plug over if that happened. I had no clue at the 
time. Kind of scary to an 8-year old kid.
