The image below is similar to what my parents always had, minus the VCR or cable box of course. We also had to get a UHF converter box when Austin got its first UHF TV station because the TV we had was VHF only--channels 2-13.
And I remember seeing ads in magazines for those conversion screens to turn a B&W TV into a color one. They basically had three color shades or bands running horizontally and were designed to tint the sky blue, the center neutral or red and the ground green, which of course rarely worked!
