Sega Saturn power pinout for power supply japanese model

[D]

who can deliver the pinout for power supply of a Japanese Sega Saturn

I have one and I want to fit a european power supply in there.

but the pins don't match Japanese model 2(white) has 4 pins, my European model 2 has 5 pins

I've allready checked loads of pages, links, etc.
All I find is region mods and 50/60 hz switches.

I allready opened up the Saturn, nowhere does it say the voltages, only on the power supply itself 5volt +volt and then two times nothing!!!!!

please help.

It can be done right? 60 hz 50 hz doesn't matter right?
only the voltages and amps right?

I am sorry. I am confused...

You are talking about ....

a) Vedio Pinout
b) Control Pad Pinout
c) Console power supply in

If it is a) or b) the follow site would help

If it is c), you would just need a transformer.

Yeah I can buy a transformer, but I had one a long time ago for a japanese PS and the thing made alot of noise (that stereotypical electronic sound effect used in movies and games)

And I do have a spare European power supply lying around.

I cannot beleive I have reached the limits to moding..........

plus another adapter will consume power, I think and will continue to make noise unless unplugged!
Call me a bitch, but I'd like to Europize (220 volts) the system.

So you are talking about the power supply.

Actually I am using the transformer (220V to 110V) for DC to power my Saturn. The power plus to the console could plug into the saturn. True the saturn plug got a special sharp to prevent you from connect the power cord inverted, but since we are talking about AC power inverting the polarity don't matter.

For your case just cut the power cord from the noicy transformer and transplant it to the spare European power supply. That's should be minutes work. Again since the power supply into the Saturn is AC ploarity don's matter.

I should have stated in more clearly.

I want to put a European Sega Saturn Power Supply in a Japanese Sega Saturn.

The Japanese motherboard has four pins which connect to the Japanese power supply. what voltages does each pin need?

I saw something like 5 V and then 5+ V and then two pins with no indication.

anyone know any links to where something like this is pinned out?

Does the Japanese saturn not use the 3.6 or 3.3 or 9 volts?

Well that is difficult to do. You must have some knowage of electronic to do it correctly. Moreover, the parts scrabs from the transformer might not fit within the Saturn.

Your best bet is take the transformer part from an European Saturn (a broken one is handy) and transplant them to the Japanese Saturn. This might invlove PCB cutting, and partally rebuilding some parts of the circuit.

Thay should be 110V AC, the Japanese Saturn got an inturnal transformer to convert the AC current into DC. The four pins would each connected to a diode to change the AC input into single direction, the current is then step down and statlized by some coils and capacitors.

I have just had my Jap white Saturn running with a Euro 240V power board. It seems the Jap Saturn does not need 9V or 3.3V. I ran 2 wires from the 5V connector on the powerboard to the 2 pins nearer the rear of the Saturn, and wires from the 0V connectors to the remaining 2 pins nearest the front of the Saturn.

I only tested it for 5 minutes (loaded up Radiant Silvergun and had a quick blast) but it seemed to run OK. To get the board to fit properly, I'm going to cut the pins down and solder on wires to make the required connections.

Thanks man, I allready bought a converter. apparantly for nothing.
Where were you all this time?
Just kidding.
Great to know I can mod it anytime, especially when my brother puts 220 VOLTS into the jap saturn, that'll fry the power supply!

It's so easy to do (attaching the wrong cable) especially when you have several consoles. I just hate that burning smell

Hi Stuntman,

Did you already finalize this powerboard swap (110 -> 220)? If so could you please post some pics?

I cut the pins down on the main board and soldered wires as shown. Before sitting the power board on top, I covered the connection with a piece of card for insulation. I've not used this console lately, but there we no issues when I had it in my cab and it survived a few sessions of Batsugun.

Thanks for the pics !

I want to do the same mod, as I have a few dead PAL Saturns at home and I'm too cheap to buy a voltage converter. Plus I don't have the Japanese power plug.

Hey thanks for the tip !

It works like a charm.

I just did the same mod today thanks to your photos. I get B&W video though, There's false contacts with the mainboard and the supply board. So I'll probably have to insulate the supply board.

Cheers.

I'm glad the pics/info helped. I don't know your setup, but B&W video may mean your TV can't deal with the NTSC signal (I'm assuming you're not using RGB).
