I got to a library to get the Waco calling instructions on microfiche. I looked up Waco because it is in 817 and beyond the Dallas/Fort Worth area. Voila, the July 1990-91 call guide has, for intra-lata calling, 0 or 1 followed by area code IF REQUIRED. Plus, I am seeing 1+7D for some toll-free service numbers. 214 area already had N0X/N1X by then, because the call guide announced the coming of area code 903 in November 1990.
