The last time I visited home, my mom sent me packing with all my old junk.
Lo and behold my Pong game circa 1970something.
Got it home plugged it in and yup - still works!
Not only that, but an original Coleco football handheld - you know the same one they're remaking now. It works too!
If you have a new one, I'd love to know if the instant touchdown trick still works. I forgot exactly, but if you mashed the right combination of buttons it scored an instant touchdown for you. (or was it a field goal?) I wonder if they got the bug worked out this time around. That would be hilarious if the trick still works!
