Power question regarding upgrading from Naomi to GDrom

[OldFoo]

Hey Guys,



I couldn't wait any longer to get my cab before getting the Naomi, so I'm acquiring a Naomi 1 mobo and Capcom I/O.



My plan is to plug and play in my KI cabinet (JAMMA) until I can get the Net City cabinet that I want.



My question is based on the assumption that the JAMMA will power the N1 mobo through the Capcom I/O.



In addition to GDrom drive, SCSI cable and DIMM board, will I need anything additional to run the GDrom upgrade in my JAMMA cabinet?



Do I need a second power supply? I seem to recall reading that I might.



Thanks as always guys - you're the best.

yes you will need to power the gdrom drive,be careful and make sure you get the voltages to the correct pins unless you want to fry the gdrom servo board

Thanks for the reply, though I'm not sure exactly what that means.



Is there a pic or a link showing exactly what needs to happen?



Thanks!

make sure your bios is gdrom ready (E version at least)

What he means is that the Capcom I/O by itself cannot (safely) power the Naomi system and the GD-Rom. You will have to power them separately. Take a look here for an example from the Sega-Naomi main webpage--->Universal Naomi Setup.





P.S.



Please keep relevant posts together and not make a new topic for each idea. (For example, "What do I need for this system..." and "about GD-Rom...") Thanks.
