My Atari computers from the 1980’s still work.
So does what is still my main computer, which is from about 2010. It has had memory and hard drive upgrades, and a newer video card, but that’s about it.
My phone is from 2017 and is going strong, though I am going to need to replace it because of evil phone company shenanigans that are not about the phone being out of date.
I have computer speakers and a TV that are ye olde – not sure how old.
I’m still playing my first pen & paper RPG, which was first published about 1978.
I still use my grandfather’s kitchen knife, and I have a nice manual egg beater from probably about the same era. 70+ years old. My wooden desk may be from about that era too – I’ve had it for 40 years or so, as well as a table.
I have Webster’s Encyclopedic Dictionary from 1940 or 1941 (as seen on the map, which shows occupied territories from World War Two in progress).
Quite a few other things.
