In a previous post, I railed about AT&T's part in keeping me from obtaining a Doorphone for my Panasonic PBX. Since then I have received E-Mail and even a phone call giving me suggestions on places to try. I appreciate that very much. However, I have already tried all of them, including the most widely-mentioned place, ProCom in San Diego. It was a lady there who brought up the AT&T business as an explanation concerning why that item was so hard to get. Necessity being the mother of invention, I proceeded to analyze the output of the doorphone adaptor, did a little breadboarding, and faster than you can say "trade embargo", I now have a working doorphone installed. The circuit and transducers fit nicely in an intercom door box. Technology IS power, after all! John Higdon | P. O. Box 7648 | +1 408 723 1395 john@zygot.ati.com | San Jose, CA 95150 | M o o !
