The home version of pong when I was 4 years old.
My friend's dad owned a small local cable station so he had access and money to get all the latest crap.
I remember he also had a brand new beta max, and I was just this innocent 4 or 5 year old kid and I was asking why the time was flashing and the adults didn't know. So I just walked up and programmed it. They praised me as being a literal genius and I was like you idiots It's just a fucking clock.
