Death adder is gonna get his ass kicked!! Ha ha

[myPinballs]

Just dug this beaut out of storage

Time to get it fixed up and give death adder an ass whooping!! Ha ha

Black screen non booter! First thing is to see if decrypted roms cure it

 

[stevebm1]

I could be wrong,but I don't think you need the sub board fitted to the main rom board,if you use the decrypted set

 

[myPinballs]

Yes I’m gonna remove that. Just burning a new set of roms

 

[myPinballs]

Well that didn’t work no different, guess this is another one that’s going to take time to fix. Board is super clean though

Did you know that death adder weighs 667 lbs and is 8'2"? That might come in handy with the repair

Hopefully something nice like the brown-out/reset IC, rather than a dead CPU.

Yeah gonna have to check all that tomorrow, no activity on the pal in the rom board or rom oe lines so not looking great.

Let’s hope it’s not the cpu ! Board itself looks almost new. Crap sega designs !!

Fixed It!

Bad PAL at IC51..

Weirdly the pal was also causing the reset chips at (IC11 & IC12) to malfunction, but once the pal was changed they were ok again. The current draw was 3.15a with the dead pal, and dropped to 2.75 a once back up and running. Only by using a separate higher spec power supply did I find this out.

 

[myPinballs]

Now, do we believe these bookkeeping stats?? How long has this thing been dead for?

Great game, pulled one out of storage 20 years ago for my kids to play, they loved it. Nice fix !!!

 

[stevebm1]

did you change the battery on the mainboard?,if so surely that would have wiped the book keeping info?

Not always the case

22 days would be a long game!
Well done with the fix
Great game

Hmm, got this PCB out again and the battery which has never ever been changed is still reading 3.1v. Is this normal,are new batteries including Duracell just not of the quality of yesteryear?

Total grail game for me! Glad to see it's up and running!
