Well done matey!!!

Seems like you had an "underpants on the outside" day in any case

Cheers,

Ralph.

[Paulie]

Edit: I checked my NNC CP on the off chance it'd be similar & the unconnected ones I have don't look the same I'm afraid. I've an unconnected white 8 pin connector to the left of the CP where the controls/speakers etc are connected & a white 4 pin connector at the coin mech. I don't know what either of these are for!

Thanks for looking for me buddy, I have a feeling I may have read somewhere that maybe 1 or all of the are for extra speaker/ sound amp or summat but I might have imagined that.

I'm sure someone will know

Well done matey!!!

Grab a decent uv bulb from fleabay, it works, just a slower process I used it on a yellowed DC and snes.

[crunchywasp]

...or if you have any mates that grow those special plants indoors maybe they'll be able to lend you some lamps

[Paulie]

I may go down that route if we don't get any sun.

Today I got new locks and fitted those. A new monitor mask but I'll change that another day, sticks and a cpo

I popped the plastics back on and fired her up. Now I was a little nervous as this is the first time I've turned it on since I started the resto, although I did test the mobo a few weeks ago. The spash screen appeared so I thought eveything was good. Unfortunately I got a I/O error so after many wasted hours I think my I/O is probably kaput I started a thread in the tech section but I've messed about with it so much today that I think I must have tried everything so I'm stumped. Also I'm missing a cable to hook up my sound board so no sound either, but the splash screen looks nice and I had a fiddle with the test mode but other than that it's been a bit of a wasted day.

[instant_classic]

That's a right ball ache! The cab is looking mighty impressive now tho!

[Paulie]

Aye, very frustrating

[jase]

The cab is looking awesome Paulie, I wish I re-sprayed my monitor support brackets know tho. I just gave them a quick clean and re-fitted them. Hmm debating whether to take it apart again now to give them a new lick of paint.

I was well chuffed with the NOS monitor mask from Craig. The old one wasn't too bad but fitting a brand new one made the whole cab look nicer.

[Paulie]

Cheers jase, yeah the bracket came out nice. I know what you mean you can probably tell I'm a bit like that too

My monitor mask wasn't bad at just a couple of very small hairline cracks that you can barely see and they were on the curves and did'nt reach the edges maybe 15-20mm in length, but Craig only had one left in stock so I thought if I didn't bag it now I may not have chance to get anothert NOS one in the future.

As I reported in my last post I've had my first set back with the cab, well in fact two of the little buggers

Thankfully I have some good news today, one of the problems has now been solved.

The first problem was when I fired the cab up the splash screen appeared then the screen went black for a second or two and I got the following error message

I/O BOARD ERROR
NO JAMMA I/O BOARD


I had checked my voltages and connections and everything seemed to be fine so after a fair few hours of messing about with it I came to the conclusion that my I/O boeard was broken.

I did a lot of trawling on the web to very little avail and started a help thread, but TBH I still wasn't really any wiser. So I decided to buy another I/O board and thechop came to the rescue.

After looking looking at my I/O with a fresh pair of eyes something stuck me. I realised that I had rebuilt my cab using my photos for reference. So I had put everything back exactly as it was when I got it. But what if it wasn't wired correctly when I got it. TBH I thought mine was pretty much untouched but I also discovered on Thursday that my transformer has been butchered and some wiring has been ripped out so I can't hook it up to my sound amp board. Now with this in mind did a little more googleing

I now found some interesting info on Andy Geezers site.

Heres how my I/O was wired before I touched it


After I cleaned it you can see I put everything back exactly where it came from


Now as you can see (bottom left of the I/O board) the 5pin JST NH connector, 2 white & 2 red wires (12V Power in) was connected to CN2 which is (12V Power out), but I found on Andy Geezers site that (12V Power in) should in fact have been connected to CN1. I'm pretty sure that one way or another this explains the fubar.

The replacemt I/O arrived from the chop today. I wired everything up correctly this time and bingo


Now I still have the issue of no sound but at least that's I problem solved.

This is what's going into the transformer


This is what's coming out of the transformer


As you can see 2 black and 2 red wires have been ripped out, why? why just not leave them where they were if they were surplus to requirement.

Anyway I'm on the look out for a replacement transformer, I've posted a wanted thread both here and on J+ but if anyone has one spare or knows where I can get one from please, please let me know.

[instant_classic]

Try messaging http://myworld.ebay.co.uk/honey0099?ssP ... EM:GB:1181"

she has loads of Naomi spares for sale and is mega helpful too!!

[crunchywasp]

glad you've got the I/O error sorted. It's looking fantastic & the screen looks ace.

Hopefully you can pick up a replacement transformer and resolve that issue just as quickly.

[emphatic]

[Paulie]

Cheers chaps,

As you can see from the photo the CPO still has the protective film on it and man that access door is still in a bad way, but I'll be sorting that out and the top access panel shortly.

Well my wonderfully kind and talented buddy Franco has stepped up the the breach and is going to take a butchers at my poorly transformer, and if he can't sort it then I doubt anyone can, so fingers crossed

Also Franny is working on one his is great looms for me so I'll be able to play both Atomiswave (using the JAMMA edge connector) and Naomi (using JVS) in this bad boy soon

and finally
I got this beauty from another good buddy of mine, Mark, Thanks a lot man


I have 2, almost complete sets of NNC art (just missing marquees) that I picked up from Craig a little while ago so she's gonna be blingin I won't be putting the new art for a few weeks though as we should be moving house and I would be gutted if it got scratched during the move.

[instant_classic]

I really cany wait to see the finished cab, its goona look seriously bling bling

[crunchywasp]

Glad the panel's arrived safely buddy! Can't wait to see the next update!

[Paulie]

Thanks again Mark, I'm well suited with it

[kevin2me]

Its just steller!!!! You've even inspired me this weekend, I picked up a near Mint Naomi C Mission Cab last weekend to join my rusted one,
I finally took out the Tools and Removed Front Cover, Speakers cage, The CP's and more off both.

Cleaned them all, the Naomi Gun Cab's CP took me hours to clean and still nowhere like urs, other one was BLACK!!!
I was so lazy and not mood big clean for same as CP, that I went down to local Car wash and Power house the bejesus out of it....
Now two clean-ish CP's, next must sort out chopping spare set of legs I have, and respraying rust CP. Urs will be my guide.

Big big thanks buddy. Cant wait to see your finished Cab. Black Artwork rocks,
