Sega-Naomi

Hi Guys,



I was wondering if you could help.



I'm trying to setup a NAOMI 1 Mobo with GD ROM in my Blast, but the board doesn't seem to do anything when I plug the power in. I'm using a power splitter to power the GD ROM.



Last night I took the mobo with gd rom to someone with a NAOMI cab to see if the board was knackered. It spun up without any problem.



I've checked the voltage on the Blast, and I'm getting a good 3.3, 5 and 11.5V (should be 12v) out of it.



Can anyone help try to diagnose what's going on? I'm a bit stuck as to what to look at next.



Many Thanks,

John

Could you provide some pictures of how it is connected in your blast?

At the moment, 2 different ways.



Setting the monitor to 31k and through the d connector and attaching that to the Naomi board. Then connecting the Naomi board to the power via 2 JVS power connectors. At this point I just want it to boot up as I saw on the test Naomi.



Then I try connecting via a Capcom I/o. USB, video directly to the Capcom I/o. Power same as before, then the Capcom I/o to the JAMMA connector. Monitor set to 14k and the firstnaomi dipswitch on to enable 14k mode.



Pictures to follow.



Cheers,

J

Ok, so 2 picies, first connecting directly to the power and directly to the video at 31k.
