OK, so I know that in the early days of FM Stereo Multiplex that often times manufacturers, like Zenith, Magnavox, Motorola etc. would design a radio that was "FM Stereo Compatible" meaning that it had a provision on the radio for an FM Stereo Multiplex Adaptor to be installed by a factory trained serviceman if one so choose to do so later on (specifically the old console stereos from the late 1950s and early 1960s).
I was wondering if that was also the case with the remote controlled TVs from that time period, that they made the TVs with a remote control sub-chassis installed from the factory if one chose to do so (the same was done with FM Stereo Multiplex early on) but then one could also get a TV that was "remote control capable" where the TV was provisioned from the factory so that a remote control sub-chassis could be installed later on by a factory trained serviceman?
If so I wonder if that was the case with my TV?
