Galaxian Namco and Midway pinouts

[Belike]

I received an original Namco Galaxian pcb from Oliver and I'm just wondering if it uses the same pinout as the Midway one.
I have a Namco cabinet, but there is Midway pcb inside at the moment and I'm not sure I could simply swap them.

Any input would be appreciated.

the pinout you post here, dont match
based on those two , you cannot swap them, but i dont know it

they are talking about DC and AC setups, also here:

Dont know how your cab is ATM ?

The Midway pcb inside is working atm., but I don't know if it's modified or the cabinet's wiring.
I will make some pics tomorrow, but the pcb looks similar to the cabinet's exterior, so prepare for the worst...

And those pics:








The Midway pcb

And the Namco from Oliver

I still don't have any idea, if the pcbs and the cabinet work on AC or DC.
There is something here about the AC/DC conversion:

I dont have a clue, maybe "galaxian Andre" can help you with this ?

what i do see is that they talk about shorting the diodes to make it a DC version
when i look at the Namco board i see that the red cable is connected at the spot where D4 and D5 should be, but they are removed, so i think the namco board is modified to use with DC

On the midway board i can see the diodes, so my guess is that that is original, meaning AC.

Galaxian (like Pac Man) is AC. However most boots used DC.

It's pretty easy to see, when you have those two big diodes, it's expecting AC.

[Etienne MacGyver]

so my theory sounds right

Does it mean that both pcb is AC and if the Midway works in my cabinet the Namco also has to?

[Etienne MacGyver]

No, it looks like the Namco is converted to DC, and your cabinet is AC, since the midway has the diodes still intact..

I don't know if this has been answered completely, but ....

Robin can answer this question, he now has my 'unconverted' Namco Galaxian PCB (for a sound issue repair) so he can check. But yesterday we did swap the Namco board in his Midway wired galaxian cab, and the game played as it should (well, obviosly no sound, but that is why I brought the board to him  )

[Belike]

Same here, both pcbs work in the Namco cabinet also, but I can't remember if my old friend did something or not with one the boards.

[level42]

This one

has been converted to DC.
The rectifier diodes were cut-out (D4 and D5), look where they hacked in the red wire...

You need those rectifier diodes if you want to get DC from AC...

It is sometimes weird that if you enter "Namco Galaxian PCB" you are directed right back here by Google 

Anyone of you guys willing to part from their Namco Galaxian PCB ? 

[ataritoobin]

Sent you a PM.

[level42]

Thanks !

So, did you guys find out if the pin-out is the same ?
