To provide another possible alternative for people, I made this one in about an hour.



I bought the 20-pin female connector from newegg for $4, the naomi pins/plugs from segashed. The wire came from a busted power supply. The red connector sleeves and on/off button are from wal-mart. There are fancier on/off buttons, but that was the cheapest one, and I like cheap. :)



I also made a gd-rom adapter, forgot to take a pic of it, but its nothing special, just a modded molex adapter.



With a little time, a decent stripping/crimping tool, and research/testing (really have to stress that like the original post does), there aren't too hard to make.



Hope this helps.

hi, i want to use an atx psu to power my naomi 1 and GD rom, but i only have Y cable with the 8 pin JST and the GD rom connector(the GD rom power harness), i'm not shure if this goes well, or i need a 8 and 6 pin JST connector cable plus the GD rom connnector...



can anyone tell me if i must buy it?



if i have to, there is someone who will sell me it ?



thank you

You have this?

If so, you can cut off the female receptacle and add (crimp or solder) an ATX connector and run mobo+gdrom drive. Of course, having a 6-pin connector besides the 8-pin would be better as it would help reduce voltage drops but even with just the 8-pin one it should be OK.



But if you want to save yourself the trouble I have fully wired ATX adapters for mobo and gdrom drive ready to ship:

Considering paypal fee's are extremely high for a small transaction etc.



Anyway I got no min order, so it works out cheaper here for people in the UK.

This was my first chance getting to solder something and I found making the adapter was quite easy this way.

Is it just me or was the gd-rom's power pinout not mentioned? Luckily I found it over at this topic: http://www.sega-naomi.com/forum/viewtopic.php?t=127

I think its also worth noting that after you solder wire to the JST pins, it's a good idea to crimp the two inner flaps closest the the pinheads down. I left the larger outer two sticking up though.

Question ??

I have an ATX supply running my mame cab. Could I split off the correct voltages to run off into the naomi but still keep the atx supply available to use for the mame pc ?



Obviously I would never run both at the same time I know that won't work, but if say the Naomi power cable was unplugged could i make the pc still turn on ?

edit: looking about also would it not be possible to use a sata power port to power up the naomi, it has the 3.3v 12v and 5v lines. Then I could have both powered up at once ??
