I turned a rare Atari 2600 Junior single-chip console into a portable

Now why can't these companies making portable and flashbacks learn a thing from you?!

I shudder to think what some might pay for one-off's like this, but yeah... if a like minded model were mass produced, I'd buy for sure. Love it!   :love:

This is some absolutely amazing designing and engineering! I would love to have a portable like this.

I have to admit to being a bit curious though, how long does the battery last?

You certainly did an exceptional job creating this unit, and I enjoyed watching the video you made documenting the entire process.

Very well done!

You should totally license the design to Hyperkin and have them make a Retron 77 portable. Would be emulation instead of the real thing, but it would still kill the awful Atgames portable.

Because it's not cost-effective to cannibalize antiques 🙄

Modern consoles get -all- their profit from SW, subs, and DLC.  None of that is applicable to FB systems.

Amazing work, and great job salvaging your earlier failed effort instead of throwing the parts away as someone else might have done in your place.

Just watched the video - very cool! It's great to see that finally finished off. What a contrast to the original VCS Portable. It's fascinating to compare then vs. now with all of the additional experience you've had and the modern resources available.

I haven't heard of this single 3-in-1 chip before. Has there been much research on it?

Nice!

I always wanted to learn how to make portable consoles but never got the chance.

But to be honest, we sure to have different tastes for console designs:)

Was it the Flashback 2 that essentially was a hardware Atari? That was more my line of thinking.

I wish I could afford something like that. Although, I'd be afraid to take it anywhere for fear of damaging it. I still use my Pocket Go because it was so cheap.

Yes, it was. The single-chip “blob” package IC was basically a single-chip VCS designed by @Curt Vendel back when “Atari” still had some modicum of ambition in doing something besides endlessly licensing IP for emulation.

Some later 2600 Jr. consoles (with Rev. 4 motherboards, I believe) shipped with a single chip inside, the C101688, which was a 6507 and TIA/RIOT combined into a single 64-pin package.  The ones I've seen have 1987 date codes stamped on them, so this must have been a change made very late in the life of the 2600.  Perhaps that's why so few of these so-called "Unicorn" consoles have turned up in the wild.  I finally managed to find one "accidentally" when looking for a replacement Jr. motherboard to upgrade to composite; I ultimately found another board and left my Unicorn unmodified.

Once you realize that it's mostly re-packaging an existing console's electronics into a different container you're half-way there. It's not like you need an EE degree to redesign the circuitry or anything.
