I can't believe this, but I found and successfully acquired a second original Amiga 1000 Rejuvenator.
This one is in need of a bit mild cleaning, but behold! The VARTA is still on-board, yet only has the faintest beginnings of leakage, and they haven't left the battery yet. How lucky is that? I'm half tempted to fire up the board and see if the clock still holds a charge! My other Rejuvenator had the clock removed, so I've never had the chance to play with that before.
In addition, this Rejuvenator came populated with a Paula and Denise, too! Not only that, but I now have a 2nd (and 3rd!) copy of the original Rejuvenator instructions. This one is pretty special as it has hand-written notes inside it from the original owner. I love finding things like that.
Acquiring a second board is an enormous stroke of good luck in our efforts to reverse engineer the thing. Not to jump too far ahead of my team's plans, but in theory we should be able to remove the PAL chips from this new acquisition (assuming it works) and put them on a newly printed board simply to see if that board works.
I have a lot more updates for the Rejuvenator coming soon as we shall begin to get the project back up and running now that the holidays are behind us. So cool!
