On another starwars note, when I was a kid in the 90s after killing (at 2-4 years old because I wanted to know why sound came on instantly but picture took time) the 70s Quasar WID color some of my first memories are of watching, and trying for years to convince my folks to let me take it apart at something like age 10 I dismantled it and later smashed the CRT (my friends and I wanted to watch ourselves on TV) and ended up keeping the electron gun because it resmebled a light saber... I still have it all these years later.
