I remember well, seeing mention of Carterfone in a magazine (at a 
newstand), at or shortly after the time.
I thought, "WOW! lots of aftermarket phones, better answering machines, 
modems, not being asked to PAY for an extension, and neat stuff!  But, I 
wonder how many years it will be before that moves from theoretical 
possibilities to actually being able to connect?  How will TPC ("The 
Presiden't Analyst") manage to make money off of it?  Will they add 
special noises to phone lines to disrupt modems, or will they peddle 
s'posedly better lines for data use?"
