How to rebuild a Sega Naomi Universal cabinet

First you need is the base
Image

Pull the cables out of the holes either side of the base
Image
Image

Attach the legs (these have been chopped down!), making sure you remember to feed the cables through the holes.
Image
Image
Image

You now should have something looking like this...
Image

The next bit is to attach the horizontal bars, which double as the monitor support.
The legs have holes for fixing the bars to the legs, and also a small notch, which enables you to get the bars the

correct way up. The one with the speaker holes goes to the bottom.
Attach the earth cables to the relevent points. (There should be a threaded bar near to where each cable finishes)
Image
Image
Image

The light box attaches to the rear of the legs with 4 Torx bolts.

Image
Image

(These next images are in the wrong sequence. I put the CP on before putting the monitor in, but it is easier to fit the

monitor before the CP)

Take 1 monitor (tri-sync in this case)
Image

and by yourself (if you're strong) or with some help, lift the monitor onto the 4 white plastic washers on the horizontal

beams. Once it's there, it will happily sit while you get the washers & nuts fixed in place.

Image
Image

Feed the monitor remote cables to the front of the machine,
Image
and attach the earth wires. Also get the power to the monitor from the cables on the right hand leg, and the VGA cable

should come out of the left hand side.

OK, now it's time to fit the CP.

Take you CP assembly
Image

Line up the holes on either side
Image

and attach to the frame with the 2 bolts & the brace bar
Image

This piccy shows the I/O & all the CP cabling connected, as it was all in the CP assembly. You can see in the middle,

the remote board for my pentranic tri-sync. It's a simple case of finding the correct wires from the left leg, and

connecting them to the I/O.
Image

Remember, this is your friend...
Image

It's a fairly easy schematic to read, as it has the number of pins on each AMP U/P connector, and it's colour, and the

cable colours.

OK, this is when the cab starts to really take shape.

Grab the monitor rear cover & speaker housing. The housing should push-fit to the rear of the cab, and then be secured

in place with 6 Torx bolts.
Image
Image

The speaker cables are colour-coded Red & White, and plug into the appropriate hole.
Image

OK, lesson 2 - fit the leg covers before the cabinet front. Again piccys are a bit backwards as I learnt the hard way &

ended up taking the front off again!

Take a leg full of unsightly wiring
Image

Take a foot
Image

and if you're using them, add the stabilisers now, as it makes life easier (I forgot, so didn't bother)
Attach the foot with the screw
Image

Attach the leg-cover. I had to slide mine from the top, but you may be able to clip it round the leg.
Image

If you have them, put the leg tops on as well, and secure with a screw.

Right, take the monitor bezel/cab front assembly, and offer her up to the machine. There are 4 torx bolts to hold it to

the front (two at the top, and two at the bottom)
Image
Image

and two screws to secure it to the CP assembly
Image

Add the gameing system of your choice (in this case a Naomi2 GD-ROM setup)
Image

Attach the access hatch cover & the base top (securing it if you want). Put machine into it's final resting place.

Image

Bootup!

Good job all us newbies need all the help we can get especially after dismantling the cab to move in to rooms or sheds or painting.

Great guide

I agree. Both of them helped when doing mine:

This is very useful, I'm rebuilding mine after a deep cleaning and painting. Ho<ever, what would be great is an explanation of how to connect all the cables of the cab.
Anyway thanks again ;)

Nice tutorial, I want one of these so bad. MvC2 on DC just isn't the same as the real thing :(

"The Same as the real thing"?

The game code is 99% identical!

Really useful guide here. Many thanks! I used it backwards to help as I took it apart.

Some input from me on taking these apart:

1) I just could not get the leg covers off without taking off the control panel.
2) There was a kinda hidden ground wire from the right leg to the bottom right of the monitor. I didn't see it until I had lifted the monitor off... which weighs a ton... and then I had to put it back on.... then remove the wire... then take it off again.
3) Monitor removal on your own is not easy!
4) I did not remove the braces or the light box from the legs. I got the legs, braces and light box off the base in one go.

Just depends on the cab, some you can slip them out, others it's too tight and you can't.

What about those yellow green cables? I remember taking a few of them out, but now don't know which one goes where.

I agree this threads should be sticked, really useful.

you mean ground wires? just connect them from the individual components to the frame of the unit
