Fixing the power supply of an old Atari 2600

"Luckily, I’ve actually dealt with this problem before, way back in highschool when I had a stronger interest in these systems. I believe this is the result of a weakened solder connection between the power adapter at the back of the Atari (where the male plug of the power chord plugs into) and the main board of the atari."

Made this mistake myself on various occasions:

Don't believe, measure!

Your hunch may be accurate. But that should only be taken as a hint where to direct search after checking the basics. Basics being: power supply voltages on the board, and clock signals (CPU clock in particular).

With those ok, go from there.

That said: fixed = fixed. Good job!

One could say it's clunky. But with bigger safety margins than modern electronics (or should I say: bigger silicon feature sizes in the IC's? :-). Basically this old gear can take more degradation before it stops working. And being a simple design like this 2600 also helps.

> I’m really bad at soldering, but that doesn’t stop me from potentially destroying things by soldering nonetheless.

That's really the only way to get better at it.
