Hooking up GD-Rom in an old capcom cabinet?

[OldFoo]

Hey Everyone!



I just bought a kit for Capcom vs. SNK 2, for Naomi GD-Rom, and I want to put it into an old cabinet that was running Marvel vs. Capcom on the CPS2 system. I have the Capcom I/O Jamma Converter, and the Sega I/O Converter along with the other parts for it, but I'm sure I don't need both. I figure I should use the Capcom one as it can take the kick harness that is already in the cabinet.



My main problem is how to get power to the GD-Rom system, because as far as I know, it needs something to be plugged into the CN2 port on the Naomi System. Any help would be greatly appreciated!



Thanks!!

Well, for starters, if you have the Naomi 1 motherboard, you will definitely need a separate power supply for the GD Rom setup. In normal conditions with the Capcom I/O, you can power the motherboard with cart roms.



However, with intro of the GD Rom to the setup, you may end up taxing the Capcom unit to power both units. The N1 is a power hungry board, and most GD Rom setups with the N1 require a dedicated power supply.



A little information for you, a NEW genuine Sega power supply will run about $240, or you can find used units on ebay when they pop up, or the more common solution, adapt PC power supplies to the power the unit. Starke, another member on this board produces adapters for PC power supplies. Drop him a line.



BTW, if you do use either Capcom I/O or the Sega unit, be sure to power the I/O's with 5V and 12V for operation.



Here's what the setup should look like:

Hello,



I have the Sega Power Supply, but I can't find anything in the cabinet to plug it in to. It has the input cord with one black and one white wire going to an end with three pins, which is labeled on the top as ACN | N.C | ACL



I'm guessing that I need to plug that into something to get power to the power supply?



Thanks!!

ACN = A/C Neutral (white)

NC = Not Connected

ACL = A/C Live (black)



Look for a spot where an electrical cord may pass through the outer housing of the cabinet, if there is none, a quick trip to the hardware store is needed for a cord.

In case anyone is wondering what is what when you look at an outlet, the larger & taller slot is Neutral, and the smaller & shorter slot is Live, and the nice round plug is Ground. And this applies for US 120V standard.
