ET phone home...
The Atari 5200 was the little known younger brother of the famous Atari 2600 that tried to replace it, although ironically it FAILed and the 2600 lived on. So why don’t we remember it? Because the aliens erased it from our minds!!1!!
The controller was notorious for malfunctioning, but was miles ahead of anything even humanity's brightest minds could muster. It had an analog stick for sensitive inputs, four buttons on the sides which influence events in mysterious ways, a pause button (WHOA!) and 12 numeric buttons.
Like, what the shit is this, is this thing a phone?
Oh, yes, it was. We at UnAnything are here to expose the truth.
Secretly financed by the Bad Future company of Apple, it was secretly a tachyonic anti-iPhone that, if you knew the future way of dialing, could [[Call Now!]] anywhere in the UnUniverse. It was among several things that helped prop up early UnCivilization as we know it, and helped connect the Moons of Ceiling Cat with a reliable, faster-than-light information network.
You could also play Shames on it, if that was your cup of tea.
