Oh yea, had to tune tv's to all 12 channels with the channel changer knob. Then they came out with them quasar, works in a drawer, had to slide out and tune each channel with tiny screwdriver.
Then cable ready tvs that had only midband, between chnl 6 and 7, then real catv ready tvs or would need converter box on old tvs that was push button, no remotes.
They bought a remote control tv and you had to put a box on the set they had to get up and change channels.
Dont think i could handle the technology of all tvs now, havent installed since 1999.
Hers to all us old dawgs, instalers and lineman.
