When was the last time you saw/used one of these?

So I found this on the side of a gas station close to our house. My question is for the younger generations, do you even know what this is? Also for those who do, when was the last time you saw or even used an actual payphone?

Another question, who knows that this is where hacking originated?
If you've never heard of 2600 you should look it up!

Just a funny thought, one day you will see this in a museum somewhere with a plaque saying "this is how people communicated before computers and cell phones"

For me I recently saw this one about 6 months ago not long after we moved to Colorado. It is just down the road from our apartment complex. I honestly can't remember the specific last time I used one was, but it was back when pagers still existed. lol
