What's the oldest piece of tech you still have running?

An electronic typewriter that my parents bought when I was entering highschool in the early 90s.

While my first works of fiction we're not written on it, my first fiction I ever submitted (it was rejected btw) to a publisher was.

I wouldn't get successfully published until the late 90s/early 00s after I had built my first PC out of scrap parts and a cheap copy of windows 95.

But that typewriter still holds a special place in my heart.
