Hi!
I'm planning on consolizing 2 slot MVS that I just purchased. I'm kind of new at this and I have read whole lot of information from this forum, but I'm still kind of lost.
I know it is not going to be simple, at least not for me :smirk: , but I'm willing to try.
I would appreciate if someone can show me something like this I guess :
http://www.neo-geo.com/forums/showthread.php?t=81108&highlight=supergun

with a layout diagram and the list of parts that I will have to buy .

Kind regards,
Jay

not to be an ass, but you should read more and look at pictures. otherwise you won't understand what you're doing or how to fix things.

here's some pictures :
http://www.sgrepository.com/modules/xcgal/thumbnails.php?album=65

look at them and you will see all the needed parts and how to mount them. minus the rgb encoder.
otherwise, it's not much different from building a supergun. you'll need to power the board and get the RGB and sound signals off it. the rest depends on your creativity and skills.

oh ... and don't use spray paint, or else you can re-paint the system every few months.

You're in exactly the same situation I was before I consolised my 2-slot. I did a few weeks of research before I did anything. Read around these forums and look at links to other sites from these forums and you'll find most of the information you need. Write down all the useful information you find so you have it in one place and then anything you still don't understand ask the good people on this forum.

I take it you've read my 2-slot thread:

http://www.neo-geo.com/forums/showthread.php?t=117523

After I'd done my research, that's all the unanswered questions I had and before I started I was a virtual noob to electronics.

thanks guys,
yeah I looked at the pics and I read these posts. I guess what I'm asking is for more visual aid. Do you guys have some pics of open mvs, I would like to take a look under the hood, it would be interesting to see where rgb converter was placed and other things.
Regards,
JL

I don't think it really matters what it looks like under the cover as long as it's all neatly packed underneath and things like video converter boards and fuses are secured so they don't move about. Just use your common sense. I actually used electrical tape to secure the fuses to the underside of the 2-slot case! It's more important that you understand which wires go where rather than how it looks inside.

fuses? the power supply should have one built in.

Not as far as I know. I used the SC200 from Jameco and everyone said I should put fuses in the power circuit in case of power surges so I did.

I wouldn't say that..... The Jameco PSU barely powers the PCB as it is.

The SC200 has a fuse in it and most people use it without additional fuses. Who is this "everyone"? It doesn't hurt to have additional fuses, but not necessary by any means for this stuff.

i never opened a sc200, but just about any other power supply's pcb i've ever seen had a fuse on it.
i actually asked my dad (he studied electrotechnics) about it, when i started working on my first 2 slot (almost 4 years ago) and he said i didn't need one, which is why i never used any.

Well, I spent another week reading through this forum, looking at the pics and looking at my mvs board. I have a really good idea how to build a supergun, but not such a good picture on consolizing.
So, here is my proposition. I will give for free a 2 slot MVS board ( or neogeo cd system with 7 games) to anyone who can help me with detailed knowledge on consolizing 4 slot MVS board, by this I mean 2 things:
1) exact list of parts that needs to be purchased and where to buy it
2)step by step instructions with pictures of what needs to be done.
I'm in Horsham, PA USA , so if you are local to me, you can just come over and pick it up, if not I will ship it free of charge at the completion of the project following your directions. I have over 900 positive feedback on EBay, you can look me up under jl2002_jk.
I really want to do this project and I'm very serious about it, I'm even selling my main cd system with over 30 games to mover to MVS .
Regards,
Jay

Ok it wasn't everyone, it was stuffmonger! Here's the thread:

http://www.neo-geo.com/forums/showthread.php?t=117523

That's really annoying because it was a faff putting those fuses in and securing them to the shell. I wish someone had said this when the issue was raised in that thread.

Ok, how about this. I will break it down by section:

Power

Ault SC200 PSU from Jameco - $20 (D-Lite bought a fuck ton of this, buy one from him at around $10 or so and save some money)

Power cord for PSU - $4 - This is a standard PC style power cord, so might have an extra one already.

5 pin din outlet from Jameco - $1.30 (you can also buy higher quality, nicer ones as well from places like Allied Electronics)

Power switch from Radio Shack - $4 -Now, you can use either a DPST or DPDT switch, providing it has atleast 4 contacts. I linked to this DPDT switch from Radio Shack because I have used it before and it works fine.

This is the power supply components. You are also going to want to pick up some 18 or 16 gauge wire to wire up the components on the inside of the shell. I suggest using a couple different wire colours to help you tell what is what when you are wiring things up.


Audio/Video

You have several choices here.

NeoBitz video encoder - $115 - If you have some extra money in your budget, most would agree that this is the best choice. Its also just about the only choice if you want composite, S-video AND Component video. Thats right, it also outputs component video.

R2N video encoder - $64 Outputs Composite and S-video. Excellent product at a good price.

JROK video encoder - $80ish - Oldest of the three, but still a very good product. Outputs Composite and S-video.

You are also going to probably need some panel mount video and audio jacks.

Left and Right RCA jacks for audio - $2 I will talk about wiring up audio later.

Yellow Composite video jack - $1 You might only want s-video or component, if so you can just skip this.

For S-video you can try either part number cp-2540-nd or cp-2640-nd from Digi-Key. I am sure there are some other sources for better connectors. Many people use to take these models from PartsExpress and mod them, but I don't much care for them. They look pretty, but thats about it.

For component video jacks you will want a red, green and a blue RCA jack. You can get these from Digi-Key as well. Parts CP-1413-ND, CP-1417-ND and CP-1416-ND. If you want to buy all the jacks at one time and have them all match, buy them all from Digikey. CP-1414-ND for a white jack and CP-1415-ND for a Yellow RCA. Choice is yours.


You will probably want some 22 gauge wire (or similiar) for wiring the jacks up. Keep all the wiring as short as you possibly can.

------------------------

Before I go any further and before anyone else mentions it, almost all the components I picked out for this summary are easily exchangable for higher quality, more expensive components. I simply picked out some common ones. Others might offer advice for better components, so keep that in mind.



First off, you will need to take apart and clean the 2 slot shell. I would suggest doing this prior to drilling it. Then go back and deburr the holes to make them smooth and clean.


The power connectors will be located on the back of the shell. You will want to measure out all this and make sure you have room around each one to correctly mount them. Some people will want the power switch on the front, most though want it around back near the input power connector. Drilling the shell will be tough if you don't have the right kind of bit. I would suggest a UNIBIT.

10502.jpg


Its a tappered bit that can drill from a small size all the way up through 3/4" or 7/8". This can be purchased from a place like Home Depot or Lowes. It can cut through the shell like butter plus it cuts down on needing a bunch of different bit sizes for the project.

Start by determining which side of the back of the shell with be the Audio/Video output area and which will be power. Looking from the back, I typically do left as power input and right as A/V.

Like this:

normal_P4130001.jpg


You will want to mark off and drill holes for both audio jacks, composite (if you want it), s-video and component (if your encoder choice supports it). Also do this for the 5 pin power inlet jack and the switch. Keep in mind not to drill to low on the back shell as components on the 2 slot board might get in the way of the connectors when you reassemble it. Check with the connectors you buy as to what hole size they need. I usually tape off the back of the 2 slot with white painters tape and then use a pencil/pen and a ruler and mark where they are going to be.


After the case is drilled for all your connectors, I would suggest temp mounting all the connectors and reassembling the unit to see how its going to look and ensure nothing touches the board. If it looks good, then continue.

Now, remove all the connectors and decide if you are going to finish the shell and how. Some folks primer and paint the shell, but I would suggest for an automotive durable finish to have it powder coated. Call around to some local autobody places and see if they can assist.


I will leaving the wiring explanation to someone else as I don't have much time to type this.

If you want lots of pictures of other folks SuperGuns and MVS consoles, you should visit The SuperGun Repository.

Very nice summary! As for wire guages, you are pretty on track. Good quality JAMMA harnesses (Like Bob Roberts') use 18ga for power and 20ga for other connectors.

Standard power colors are:
Ground - Black
+5V - Red
+12V - Yellow or Orange

errrr.. N*G doesn't use -5, right? But if so I think it's blue...

Hell, you pay for the parts, I'll do to the consolization for you for the 2 slot. (And, you know, if you have a MVS kof2k2 to throw in, that'd be sweet.) Send me a PM if you're interested. I was going to consolize my 2 slot anyways, this will just mean I order 2x the parts.

Since you're wanting to consolize a 4 slot, isn't there some concern about whether or not the sc200 can properly power it? I think I remember in D-Lites thread about it working for 'some' 4 slots.

Most people *want/request* the power switch on the back? Really? Sounds ridiculous... As I see it, people usually buy these units once they're finished and if the consolizer had the bad taste to put the power switch on the back, then there's nothing they can do about it... but of course I agree that if you use an ugly switch then it's better to keep it out of sight...

I don't understand why this issue has to keep coming up. Does it really matter where the power switch is? And yes, some people do prefer it out of site on the back.

Just another thing to argue about. I usually put them on the back because the front looks cleaner that way, but many consoles have the power switch on the front. Funny enough most computer put them on the back. Either way it's just a pissing contest and we can all agree that you should just put it where you want.

really? I know a most computers have a main power switch in the back, but all the ones I've seen have some kind of power button on the front... ;) :make_fac:

I misread your sentence "The power connectors will be located on the back of the shell" (obvious) as "The power switch will be located on the back of the shell" (debatable). My bad. Still I think the switch should be located where it's most easily accessed and that's no doubt the front of the unit...

I put mine at the back and most units I've seen have them at the back. I think they look ugly at the front, even if they're nice looking power switches. I reckon it's just as easy to slip your hand round the back and turn it on as it is to turn it on at the front. It's definitely down to personal preference though...

I would agree about putting the power switch up front if I could find some really nice power switches that would be suitable and not cost an arm and a leg.
