As some of you may have seen, joethezombie published his outstanding work on reverse-engineering the Rejuvenator to Github today.

I'll never - nay, we'll never - be able to fully repay him for his incredibly meticulous and selfless work on this project. He not only successfully reverse-engineered one of my original Rejuvenator boards, which he was running in his own machine, but he even discovered and fixed a few bugs found within the boards that shipped back in the early 90s.
The new Rejuvenator brought to life by Joe in April, 2019 - two years ago. I hope everyone that wants one can have a sparkly one like this some day.

He also made the license for the future work on the Rejuvenator done by anyone very clear by applying CERN Open Hardware License Version 2.

Any projects, additions, alterations, or improvements based on this Amiga-1000-Rejuvenator project must be openly shared, including software or PLD coding.
In other words we're all in this together. And we’re not here to make “Amiga Scene Cash” (nothing wrong with that, it's just not a goal of this project since we're recreating someone else's work).

We’re trying to preserve an important part of the Amiga's modder history, knock down the crazy prices on Ebay, increase the supply a little and make this remarkable tech available to more folks 30+ years after the original product was born.

I would go so far as to also hope, if not legally demand, that Greg Tibbs' name be on any printed silkscreens on any Rejuvenators made in the future if we get to that point. R.I.P. Greg - we haven’t given up yet!

I would encourage everyone to read all of Joe's posts and documents on Github as they are extremely helpful and informative.

The only thing today preventing brand new Rejuvenators from being built (besides the kind of crazy chip and electronic parts shortage going on worldwide are 4 read-protected Pal chips.

Three talented engineers and Amiga fans in Germany have volunteered to try and figure out this last piece of the puzzle. If they are successful it will be glorious. If they are not, I will officially end the project from my standpoint and hope that what Joe has put on Github might be enough for someone else to unpack some day.


I received my original Rejuvenator in the mail today safe and sound. (Thanks, Joe!)

This is actually one of two that I'm lucky enough to own. I believe this particular board to be one of the earliest production models. I have a slightly newer one, too, which I use in my daily driver A1000 and that's where it shall stay for now. If I ever get one of Joe's new boards fully assembled, I will swap in the the new one for sure and keep the original Greg Tibbs version in safe keeping.

The Rejuvenator that was reverse-engineered by joe. Snug as a bug in a rug.

This what we all want in our Amiga 1000s some day, right? I know. Just hang on a little longer. And work those prayer beads, yo.

So! Now this old board will go on a long, kinda scary journey all the way from Seattle, Washington, to Germany (scary because I have a friend who recently lost a Rejuvenator in the mail going across the pond just a week ago...). Please, Lords of Mt. Olympus, protect this package on its long and important journey.

If this thing gets lost that'll be that!

The other risk, of course, is the PALs themselves could become damaged. Hopefully that doesn't happen before their secrets are pulled out first.

Also, I want to set some expectations.

While I personally have very high hopes Team Germany will unlock the secrets of the PAL chips, Joe is no slouch. He knows his s*** big time. But we’re making this change to simply get more minds into the room to try and coax the the equations out of hiding.

So, yeah. Bon voyage, Rejuvenator Board, and good luck on your final journey before coming back home one last time.

Team Germany/A1K:
We are all rooting for you so hard. If (and when!) you succeed, that noise you hear coming from the West will be our combined shouts of jubilation and triumph. Bring us home, boys.

And oh yeah, it'll be party time! Beers are on me.

If anyone can do eet, zee Germans can...

Many times I wonder how the hell the Allies won WWII given how advanced German technology was then compared to what we had. Thank God we did, and that the Germans had a crazy man with an ego problem at the helm.

It sure looks like it's possible by probing all the outputs.

So I'm going to be optimistic and say it's going to happen!

Wow, it's great to hear some news from this ambitious project. I salute you, joe and all the other individuals involved! As my A1000 ist the cost reduced version without the daughterboard I'll probably never have a rejuvenator in my box, but it's still quite exciting to follow the development here.

Godspeed, guys!

Very interested in this project. The 1000 was the most beautiful Amiga and bringing it up to speed is a dream of mine.

A very positive development: my Rejuvenator seems to have finally made it across the pond!

Your item is being processed by customs in GERMANY at 8:56 am on June 27, 2021.

It's only taken nearly 2 months...

After it was returned to me the 1st time...

So, presumably, it should be delivered some time in the next 1-4 weeks.

Wow, that's incredibly nuts, for sure! Here's to hoping it arrives intact and without delay.

Pretty ballsy to entrust that to USPS. None of the shippers seem to be worth a damn these days...but USPS has been the lowest of the low in my experience the past year.

USPS was the cheapest solution I could find - and they were all crazy expensive.

I'm doing this as a service to the community. And while I was nervous about all of the shipping options before me I still wanted to be mindful of the expense (even though the item inside the box is worth quite a bit if I were to slap it on Ebay).

It's not delivered yet, but the fact it actually made it to Germany after all this time allowed me to finally stop obsessing over that terrible tracking page that is sadly lacking in details.
