I still go BERZERK !

StuDaBaker:
Bolted on ashtray! LOL! That's totally ugly and awesome at the same time! I can see some dude sitting on a bar stool in front of that thing with a row of coins on the glass with a cig hanging out his mouth and another burning away in the tray.

Awesome! I scored 2 non-working Berzerks this year and got them both working pretty easily. I sold one and kept one. It is one of my favorite games now.
The problems I experienced were bad connections at the cables and bad RAM. That is all it took to get both of mine going.
If I can be of any assistance, let me know. BTW, mine were serial numbers #250 and #10xxx (Ten thousand something) Quite a spread between the two, and it was evident in the quality of the stenciling on the sideart. The #250 machine had a much better stencil job than the later one. I kept the later one, however, since the cab was in better shape.

Level42:
Great !!!  Any help is welcome ! You didn't have any battery corrosion ?

Serial numbers of the machines two are in the 2000 range, one is in the 3000.
The stenciling is far from perfect, the logo doesn't really allign (at least on some of them).

hatrick:
Suprisingly, I didn't have any major acid damage on either board even though the batteries were still in them. I did immediately remove the batteries once I got the game home.
I left the battery out of the one I sold, but on mine, I added a 3.6 volt rechargeable cordless phone battery mounted at the bottom of the pull out board tray with Velcro.
You have a real advantage having multiple machines, you can swap parts all day long to narrow down the culprit. Having 2 machines side by side made my troubleshooting job a breeze. 
I replaced the original RAM on the VFB-1000 board with 4116. The nice thing about that is you only need to fill rows 9 & 11, so you only need half as many chips and no modifications to any traces or anything.
What monitors do you have? one of mine had a K4600 and the other a G07. I kept the G07 since it's a more common, and better monitor in my opinion.

Level42:
Yes indeed having more machines (and boards) around is great to fix them all hopefully...

Already did some work. Since it's very technical I put it on KLOV forum (I hope on Mark chiming in....although he might just be testing new ZZPU boards right now ! ). Here it is: http://forums.arcade-museum.com/showthread.php?t=109967

The one machine that I checked from the back has a G07 (see pics) which I'm happy with (hope the others are the same).

About the RAM: I've seen more people replacing the 2114's with 4116's but what I wonder about: On Williams machines everybody tries to get rid of the 4116's because of their heat production and unreliability. I've got a big stack of 4164's here, would they work with some modification ?
