My favorite “old tech aging in an interesting manner” reference is the digital displays in the original Star Trek series. This was before LEDs and LCDs, so they used the ones where the numbers simply rotated on a drum beneath the display opening.
Quaint, of course. Yet, like you, I also love watching this “aging” process because it speaks volumes of how far we’ve come. AND how even today’s “advancements” will soon look quaint as well.
