earlier?

Dear Noel

(good point Vint - thanks)

Yes, as you say, the Altair and the rest of the personal computers had
not come until the mid 70s.
What I'm curious about is a more abstract point - on the modem side
rather than the computer side, why is Carterfone decision such a big
deal if modems were already available for use on the normal phone
line? Was it, as Vint says, price?

Johnny
