[ih] AT&T, carterfone, the 103, and why didnt BBSs start earlier?

[David Mills]

Vint,

I recall that 103s were $25 per month; that's when a POTS line was 
$7.50. I used an accoustic coupler anyway. After the FCC Carterfone 
decision AT&T began offering Data Access Arrangements and offbrand 103s 
became available. I had the first DAA installation in Michigan. Ma Bell 
sent literally a fleet of cars, trucks and installers to light up the 
thing. The installers ignored my ham radio phone patch, which 
technically was illegal, but the installers didn't care. Upon returning 
to the US in 1972 I called to order a DAA and the operator asked what 
color I wanted. True story.
