If you every go to Amberley Chalk Pits museum, there is (or was) a display there of old technology - phones, radios, etc. My kids found it very amusing how much of the technology on display were things that I had either owned or used for work - at least they did once I explained what they were!
I was in the Berlin Spy Museum in 2019 and was asked by a couple of teenage girls if I knew how the dial phone worked on an interactive exhibit. I felt very old at that point...
My first ever dial up modem was the Alcatel Frog.

I found a bargain ISP that charged a flat 1p per minute for internet connection.
Aye, them was the days ....
