When I first starting buying Atari 2600 consoles for modding purposes back in 2000 (right after my website became famous) I was lucky enough that my first Atari 2600 Junior had the ultra-rare “single chip” variant inside.

Of course this was “portablization catnip” for me so I desoldered it and tried to make a custom PCB.  My skills at the time weren’t up to task and I feared the chip dead. Had I know then how rare it was (I’ve never found another since) I probably wouldn’t have tried but can’t change that now.

Flash forward to fall of 2018 and I come across the project in a junk box while moving out of the Ben Heck Show shop. Decided to give it another go and I have help this time – my friend Parker Dillmann has an intact single-chip 2600 Junior so we can cross reference to it.

I documented this near-year-long process in the video below. You can also click here for the full photo gallery with notes.
