I have the Commodore64 my family got used when I was 8.
I’ve had it less long, but the sewing machiney mother bought after she left college is older than that.
And I inherited it even more recently, but also have my maternal grandfather’s electric hair clippers from when he was a teenager, around 1960.
And I bought my house most recently of all, but some of the wiring dates back to 1926 (the house itself was built without electricity in 1880).
I cleaned up when I moved, so the oldest gadget I have right now is a 15 year old MSI laptop, still happily running with linux.
You should throw it a quinceanera. Put it in a dress and buy it a small car.
I have a few, but the one that immediately came to mind is my HP16c calculator.
i have an old magnavox TV from the early 70s, with the wooden slat curtain thing you pull in front of it.
Old 8 track players,
my great grandfather was an electrical engineer and made some custom lighting controls in wooden boxes, with dials and meters and switches, he did made it all for his church!
from that same grandfather, he had some portable reel to reel tape recording stuff, an old portable projector that comes in a cast iron cowl.
tons of stuff that everyone makes fun of me for holding on to.
A ferrite core memory module, circa 1956 at a guess.
Our old pong console. I don’t know if it still works because it’s been boxed up for over a decade at this point.
Oldest in use? Probably my old texas instruments graphing calculator, but it’s dying. I got it back in the early nineties for college, and my kid was using it last year with homework, but the screen is failing and it sometimes just freezes until you pull and replace the batteries. So only kinds in use, and barely hanging on.
My VCR is newer and still sees use rarely, but was used daily for a few years in the early naughties.
Wait! The phonograph! It’s still functional and my dad got it in the early eighties, so it’s older than the pong console, but I think calling it electronics is dubious, so I dunno if it counts. But it’s the oldest functional electric powered thing we have that I know of.
Not entirely sure but this has to be one of the oldest and is fully functional.
4 channel mono audio mixer, with germanium transistors only
From the mid-sixties
Cool. I’ll give you $50 for it 🤪
Casio CZ-1 synthesizer, produced in 1986.
Got my aunt’s rotary phone in the closet.
Don’t know if it counts, but my suitcase record player has vacuum tubes. Still spins but it needs a needle.
Probably my Canon AE-1. Not sure of the exact year, but the model was made from roughly '76 to '84.
I’m still the original owner of one of these 1982 Pac-Man consoles. Actually, I thought it was lost for decades but my aunt discovered it during a basement clean out and gave it back to me. Last I checked, it still worked. But the volume is so dang loud that I remember I always had to play with it outside.
Fridge. Older than me
My speakers by far
Probably my dad’s electric turkey carver. It was a wedding gift he got in 1980
I have my old Speak & Spell. It still works.
I have an electric singer sewing machine from 1964 and another one from around 1950. Amazing how well they work.
