Moonwalker pcb resurrection

[Belike]

Clean it thoroughly with white vinegar and a brush. Then wash the vinegar residues away with alcohol.
This at least gives you  a proper look at the PCBs traces to examine the damage there.
Maybe you're lucky and this will be enough, but it looks pretty nasty.

I did the treatment, nothing changed.


Any hope to fix those circuits somehow?

I don't know if soldering wires to replace the broken connections would be doable.

[Etienne MacGyver]

If you are patience, have a little solder skills , and some spare ribbon cables (lots of loose wires looks like a mess  ), then its worth a try

[Superully]

looks like you need lots and lots of wires for this one ...

One other option is to look for a cheap replacement board. Sega made a bunch of different games on this hardware (System 18), and I doubt that all are usually as expensive as Moonwalker. Here is a list, though they are all not really common, so it may be a little difficult to find something: http://www.system16.com/hardware.php?id=702
However, I can't guarantee of course that all boards are exactly the same (though they should be). If you get one all you need to do is swap the chips.

Thanks for the tips, I will do my best to save it!

(noob question mode on)
Swap the chips means only the removable ones or the "fixed soldered" also?

i think u'll just have to swap the daughter board (no chip to swap)

[Laschek]

Yes, in this case you can swap the entire daughterboard. I'm not sure about the motherboard, there might be some game specific chips as well. If so, then they will be socketed and easy to swap.
No need to unsolder every single part

Thanks guys, seems like I found a Clutch Hitter pcb, that's a real idiot american baseball game, I think nothing we could loose if I exchange that silly game with Jacko!

I tried to buy that Clutch hitter from Quarterarcade, it was on their stocklist, but Anthony didn't find the pcb, so I have to look for another one.
There are a few in ebay, I will send some "best offer" to the sellers.

Package arrived today


A Clutch Hitter pcb???!! ???Who ordered this garbage?


If it is already here, let's try to swap the daughterboard and the CPU with Moonwalker


This almost 20 years old battery still works fine, but has to go


Into the Big Screen and fingers crossed
