I've put a couple of rolls of film through it so far. I wasn't trying to capture anything stunning, just testing it, but I quite like a few shots. You can see the results here.

Any other vintage camera enthusiasts around or, more broadly, anyone else got any old tech that's still going strong?

I have a LaserDisc player, a VCR, and a VCR/DVD combo. I also picked up a TV/DVD combo. The LaserDisc player was sold by a school and is a true workhorse, though not one that auto-plays both sides. Gotta flip it over like a record after about an hour! 

I recently picked up a TV/cassette/radio combo. Only the radio works. It might be a good reason to start tinkering with vintage electronic repair! 

I also have a Yamaha Clavinova from 1998... It has a floppy disk drive! Everything still works on it. And it weighs nearly as much as me (it's about 70% of my mass!).

When it comes to photography, even my digital stuff is getting old now. My venerable Nikon D90 is 16 years old. Doesn't get much use, but still works.
