I think my dad still does.
I believe some of the first computers he used had mercury delay line memory.
He's 90+ now ... and still programs.
He got his very first hearing aid about a year ago ... and has quite a
bit of fun going in and tinkering around with low level code in it,
to be able to further customize it to get it to behave exactly as he likes.
