My launch 64 still works and is plugged into my HDTV.
I actually got mine a day early. I think. We had it pre-ordered at Toys R Us (oh, the good ol' days when there weren't long lines for console pre-orders/launches), and we were driving by the store the day before launch, so my parents were like what the hell, let's see if they have them. Went in and got a console and Super Mario 64.
Looking back that sounds somewhat unlikely to have actually happened, as they may have just gotten the day mixed up, but at the time consoles launches weren't taken quite as seriously as they are now, so I could see Toys R Us of all places doing that. All I know is my 8 y/o self was like "Hell yeah, got this early!"
