Re: "Genie" telephone
I came across an MEDL chip in a Tribune telephone andalso couldn't find data on it. But as the other 2 ICs were Texas Instruments (and I have the appropriate databook on the kitchen shelf...) I quickly found those were the speech circuit ('hybrid', replaces the induction coil) and the ringer. Since the unknown IC linked to the keypad, I deduced it ws the dialer.
