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.

Original Gameboy.

Still works.

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.

I own a model electric train that was built in 1937. So, 88 years young?

Runs well, it’s kinda weird to think that this was a toy and this level of build quality was normal. To be fair, it wasn’t exactly. This was a high end toy aimed at affluent teens and young adults. It would have been equivalent to buying a new PlayStation. But still, I have trouble imagining any toy you could buy today that would hold up like this.

I have a battery operated tube radio from mid to late 1940’s. It even works, but the battery it uses is getting rare and quite expensive. And my country doesn’t really use AM radio broadcasts anymore, so it’s more of a curiosity nowadays.

I also have a lot of working stuff from the 1950’s, mostly radios and amplifiers. Great gear, and much easier to service than their modern counterparts.

A ferrite core memory module, circa 1956 at a guess.

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).

An originally original gameboy. Still worked until about 2 years ago. I assume there’s just a little battery or a capacitor that needs replacing, but I haven’t had the time to look into it.

My husband has a collection of obsolete technology. The oldest thing he’s got in there is a VT100 terminal.

I have a radio from the late 30s, though not in working condition. And a radio from 1961 that I use regularly

I have an electric singer sewing machine from 1964 and another one from around 1950. Amazing how well they work.

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.

Don’t know if it counts, but my suitcase record player has vacuum tubes. Still spins but it needs a needle.

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.

Fully functioning Commodore 64, monitor, 2 floppy drives, printer, and several joysticks.
