An iPod. It's still the same iPod I got for my birthday 20 years ago. It probably still works... If I'd be able to find a cable for it.

Audio modem. I think I have one in the bottom of my spare cables box.

I own plenty of Libreboot computers without Intel Management Engine (2006-2009 era). For the average user in today's world, I don't see many people using them unless definitive proof came out that the government uses the IME to spy on them. These 2006-2009 era desktops/laptops can have the entire IME firmware removed, along with a 100% free BIOS. I collect as many as I can.

Was it shaped like a sports car? Those were radical.

Echo detector. Piece of shit only picks up the weakest artifacts.

When I was a kid my family owned a device whose sole purpose was to rewind vhs tapes.

Once I have seen an offer on eBay for a similar device, but for DVD's.

Yes, really. It was that time, and it was almost serious ;)

I have a handheld analog radio scanner. Once upon a time it was fun to listen to local police frequencies, air traffic control, cell phones and cordless phones and so on.

Everything is digital now, except for the air traffic control so once in a blue moon I might listen to that.

I can do one better than that, I have a battery powered handheld TV that only works with analog NTSC broadcasts and does not have a composite input on it. It's therefore damn difficult to get it to display any kind of picture at all these days. The only way is to broadcast at it with one of those short range toy transmitters, or hack up your own.

I have a few PDAs from between 2001 and 2006 lol

Tape device so you can plug your phone into car stereos that don't have Bluetooth. Some cars just have cd deck/player and no aux input, no Bluetooth. Really new cars will have Bluetooth for phone control. Really old ones with cassette players you could use the tape gadget. Not so much in between.

Old flash drives, that were only like 1gb when that was supposedly sufficient back then.

Headphones with audio jack because most new phones have usb-c ports only now. Although I bought an adapter for only 10 bucks.

A/V cord consoles and devices.

I had a VHS rewinder too. Also that reminds me I had a mechanical "crank" playing card shuffler which would probably be an antique now. Lol.

2 Garmin GPS, one handheld and one for the car. I've been using my phone for directions now for years, but I suppose I'll hang on to both units for a bit longer.

I still have a modded WD TV Live Plus media box in the back of a drawer somewhere.

I have an old PCI TV tuner card. It predates the digital TV switchover so I have a card that can't be plugged into modern motherboards for which no signals are broadcast. Plus I'm sure there are no 64-bit drivers ever made for the damn thing. At this point it's ewaste.
