This spurs a great memory- my father and my best friend’s father worked together at ADP dealer services in the 70s.
Once, during a sleepover my friend (we were around 8 at the time) put the phone on an acoustic coupler modem and used the connected terminal to log into the DEC minicomputer and introduce me to the joys of Colossal Cave Adventure.
We were lost in time so much that his dad was more than a little upset when he got home because he’d been trying to call his wife before hitting the road home.
I didn’t get any real exposure to computers for a few years until my dad bought a TI 99/4a from another work friend. Of course one of the first games was their version of Adventure and then Zork style games.
Just picked up a TI from Facebook marketplace the other day- it’ll be interesting to see exactly what the nostalgia hit is going to be like…
