Never owned an arcade machine before but this naomi unit out of a working machine became available to me for $50 so I figured now was a good time to get into it. I'm hoping some of you arcade guru's here could school me on what I have and if it was a good deal. It was a spur of the moment purchase so I didn't have time to research it but for $50 I didnt think I'd lose much. So what can I do with this unit and do I have everything I need to hook it up to a computer monitor and get video and audio?
Wow! Congratulations that's a great price:thumbsup:. Have a look at the prices on the WTB thread for an idea of the bargain you got. Unfortunately I'm fairly new to this as well but I connect the VGA port on the MoBo direct to a monitor (although I found the frequency was out of range for my TV) and similarly pump the stereo output direct into an amp. I notice you have an amplifier board so you could connect that direct to a set of passive speakers. Unfortunately I only have carts for mine so cannot advise on the setup of the GDROM/DIMM. To Play you will need a Jamma Loom to connect to the edge connector in your 3rd picture. (See here for the pinout http://www.coin.demon.co.uk/jamma.htm) I wired mine upto a 15 Way D-Type connector and use Neo Geo Joysticks.
Thanks! I just bought an updated net dimm for it as well. I've been reading up on these quite a bit and I think I may look for a universal cabinet for it now instead of consolizing it.
$50 for all that? You've possibly made NOAMI bargain of the century! Very well done! Anyway, on topic, NAOMI outputs VGA natively and you can connect it up to a monitor, it supports 15KhZ and 31KhZ which can be changed via a DIP switch, or you can use the VGA cable to connect it to the JAMMA board which you can use in a normal JAMMA arcade cabinet, or use a supergun and output to SCART. You have a sound amplifier board there, looks pretty differenct from mine but it has connectors for connecting speakers to and it should have a volume adjustment pot or cable that can connect up to a potentiometer for controlling the volume. And then once you've done that, just plonk in a GD ROM into the drive (remove the screw before attemtping to remove cover) or replace the standard DIMM with a ROM cartridge, or upgrade to a NET-DIMM (as you said you are doing) and get a NET-DIMM NETWORK security key and the official games, back-them-up or get backup versions, decrypt them and stream them over the network to the NAOMI via a PC.
thanks, I thought it was a good deal but I wasnt sure since I've never bought anything arcade related before. Sounds fairly simple to get up and running, question is what about controls? I've read you can modify dreamcast steering wheels to work, what about controllers? If I decide to get it up and running before I get a cabinet I'd need some sort of controller to play. Is it just a matter of getting the correct wires from the controller to the correct pins on the jamma board?
Well using the JAMMA pinout, there's 3 buttons and U, D, L and R lines, each line gets shorted to ground to trigger it, so you'd have to build it around that principle (i.e. you can't hook it up to a DC controller unless you hacked it to pieces). There's also buttons 4, 5 and 6 on the board with the JAMMA connector on a seperate pin header. If you use a supergun you can plug a megadrive controller into that.
I found this guide indispensable when working it out for the 1st time... http://www.sega-naomi.com/forum/viewtopic.php?t=1265
That's a a sega audio amp, the same one that comes in a naomi cab etc. The two 2 pin AMP connectors on the right hand edge output the amplified signal. You have the wiring already terminating in bare wire by the looks of things. You could just run them into a pair of speakers. You got a great deal. Is there a disc in the GD drive? I'd guess sports jam given the manuals (which is worth almost nothing).
Great find! Yeah, I think a universal cabinet is the way to go if you have the room. What games are you looking to pick up? ^_^_^
Lol, yeah - it pays to check thread dates ;-) I hope that, if you have arcade PCBs too, you don't put them on the carpet like that!
Haha, my bad. :encouragement: Arcade PCB's definitely don't spend any time on the carpet in my collection. ^_^_^
