Here is the Repair of Board #1 (not pictured installed on Chassis), this board was the worst condition of the Frenzy Boards... I am missing two decoder chips, anybody know of a replacement or know how to make a replacement?

First Board had UNREG 5v not feed the LED Lamp Circuit pretty much breaking the reset circuit, there was also a bad resister that would not allow the reset button work.

after fixing those issues, the board stopped at two blinks, using a logic probe determined Pin 8 of the 1E nvram was floating, found another broken trace, and the board fired up. I am guessing the other boards will be much easier.

Yeah, both the berzerk and frenzy were at gamewarp in full force.

I have not built a test set to work on the remaining boards, i was using the board out of a machine, but that went back to the owner, i have a complete set of berzerk boards i need to mount, and start working on other boards, but been side tracked with Qbert, DigDug, And some other boards :(

I have several non-working Berzerk/Frenzy boards, do you have a write up or advice on how to go about fixing these old boards?

Same here....got a couple of sets, some boards working, mainly the main boards dead though....would be nice to fix m up...

Nice chip tester, just had a look, over 500 euro's here.....ouch.
 
I would just like to say that the Frenzy is still running strong. Ran for three days straight at Gamewarp and I just finished up a few games on it tonight. Big thank you once again. :)
 
Hamster like fixing boards... and to think, i think you got a free repair out of me on that one too..
 
You can send the bill to Jack. :D

Actually if I do owe you just let me know. Asked at GW but you never responded.
