Re-installing a TouchTone keypad in an ASR-33

I recall during the 70's listening to Chicago Symphony rebroadcasts from WFMT in Chicago, where GTE was one of the sponsors. Since WFMT standards prohibited pre-recorded commercials (they were always read by an announcer), they had to be a bit more interesting than the usual noisy garbage served up on radio. The GTE spot would typically highlight one of the GTE companies, such as Automatic Electric, Sylvania, Philco or Lenkurt and describe their products. "Gee--no, GTE!" Now, GTE seems to be as forgotten as "The Bell Telephone Hour". Back then, most of the communities in Silicon Valley were served by Pacific (Bell) Telephone, with the exception of Los Gatos, which was a GTE outpost. I don't know what the inter-network interface was, but it must have been something along the lines of acoustic couplers, because the quality of a call to Los Gatos was execrable. A 300 bps modem connection was difficult to say the least. --Chuck
