Oldest tech stuff in your possession?

[Heatman]

The oldest tech stuff that's currently in my possession is my father's pager. I was fascinated by it that I couldn't let it go. It's still working very well like a today's tech.

What's the oldest tech stuff you're still using?

I have plenty of old tech stuff I still use, mostly old gaming stuff of varying ages, from the 80s onward and so on.
