I still go BERZERK !
Level42:
...when I watch this picture. I love it :)
It's amazing to find ONE Berzerk over here at all, let alone THREE ! I've never seen a Berzerk for sale over here. The only one I know to exist in Europe was Luigi's machine.
Just reserving some space for my restoration here.
I've powered up all the cabs. None is working. All monitors do seem to work fine though. 2 give "garbled" pictures, 1 is black.
I've dug around the KLOV forum and found some bits of good information there, plus this very nice repair log:

So first thing to do was remove all the ZPU boards from the machines and get rid off those :angry: :angry: batteries that have killed so many Berzerks.
Desoldered them. Interesting trivia: one side of the battery desoldered really easy (at 400 degr. temp). but the other side was much harder to get flowing easily. Must have to do with the polarity and/or the acid.
Next I neutralized the acid with vinegar (I used the "cleaning vinegar" sort, not the one you use on your salad). You can actually see it reacting with the acid at some places (f.i. between IC legs) because of the bubbles !! After some time I rinsed the part of the boards that were effected with water and then dried with my wife's hair dryer.
So far, I've seen three flashes/beeps on one of the boards which apparently means that the ZPU board is actually working (although it could still have some problems). My next step will be buying a SCSI cable to hack up and use it instead of the old ribbon cables, even if it's just to rule that possible cause of trouble out. I'll also try a PC power supply instead of the original (for testing at least) because I've read that the original Stern PS is not very good.
Some more pics:
About the last pic....could there be a minty CPO under that stuff ? ;)
About the envelope with the docs......I couldn't bring myself to open it.
It looks so sweet that it has been untouched for almost 30 years....
ckong:
Wow, those cabs still look awesome after so many years. You won't have to do that much at all on the outside, it will mostly be internal/electrical restoration I guess. About the enveloppe, put my address on it, and a stamp and send it to me. I promise that I will not open it :blah: :blah:
Spyridon:
Those look great. At least you still have two original sticks in there. Outsides are in great shape. I'm assuming you will fix all three and sell off two.
ChadTower:
There is an ATX-Stern adapter out there if you hunt it down. That might help. I never had a power supply problem in mine, though.
It was the transistors in the battery area that were my problem.
Those are some great looking cabs. I'm still holding out marginal hope that my bat stick will arrive someday.

I hate you... ;D
