    I'm building a MAME board for this cab, which will be swappable with the Naomi Motherboard.

    Watch this space!

    Cab supplied by Parris, Cheers mate! :thumbsup:

    Sounds like it will be a good setup. I have a jamma cab with a mame pc that's also swappable with other jamma stuff. I would love to get a Naomi some time.

    You are very welcome - glad to see it made it up into the games room! No knocked paint work I hope ;-)

    I'll look forward to the MAME!

    No knocked paint, I took it to pieces and rebuilt it in the games room.

    The monitor and the base were the two heaviest parts to get upstairs.

    The monitor only fits through a normal door sideways :rolleyes:

    I managed not to injure myself till today when I put my hand in my pocket to pull out a £1 coin to put in the cab, and poked my finger on the end of a small screwdriver I had in there, rofl

    First the board...

    [​IMG]

    MDF so ugly, so easy to work with.

    Then the components...

    [​IMG]

    Abit NF7-S mobo, WD 40gb HD, AthlonXP2500+, Radeon 9800Pro 256mb, 512mb Corsair Ram. Should be plenty for all 2D MAME stuff

    Already it's taking shape, more to come tomorrow!

    Nice!

    I would say, though, considering the spec of the stuff you have there (not the greatest, most up-to-date spec, but nothing wrong with that) you could save some space by using a Shuttle or one of those really slim and small cases you can get. That said, I understand the appeal cost-wise of recycling old bits you have lying around ;-)

    As for what it'll do - it'll be OK for older stuff but you might find a few newer games struggle. Nothing to worry about really, though - if you really want them, get the board ;-) heh.

    Let us know how it goes.

    I actually didn't realise this was going to be a MAME project of such longevity, I just thought it was something you were looking into lol. Cool!

    Okay, I could have sold you the most perfect small factor HP PC that would fit right onto that board with enough room to swing a small cat, plus it's spec would have been fantastic.

    However, are you ditching the motherboard? If so I would take it back off you for £30 - feel free to off load the cart for £40 on eBay and you'll have more than paid for the parts you currently have, or perhaps just about purchased a convertor for the monitor. It's a good Toshiba screen, but you'll still need the 15k convertor for it.

    They are about £80-90, but retro might know specific makes to go for.

    Plus you'll no longer be using the internal PSU, filter or amp. Again, I would take those from you if you were not thinking about returning to Naomi again.

    I think it'll probably do for what I play, nothing more advanced than SFIII, but i'll be setting it up tonight I'll keep you posted.

    If I felt the need to play any 3D stuff I'd probably buy new parts, but my X2 5200+ SLI PC doesn't even run newer 3D games flawlessy, doen't feel like I'm missing out on much tho (eg SF:EX is pants) cept mabe radiant silvergun, but the saturn emu runs that at full speed.

    I planned for this to be modular, so It'll just be a case of slidding the boards in and out plugging/unplugging leads. I wanna keep it original as much as possible

    I'm not gonna make use of the IPAC tho :( I have a JPAC-JVS on the way which I think will suit this project a bit better since I won't have to do anything with the wiring loom :p

    Okay, if you ever off load any of the guts of the unit, let me know and I shall take them off your hands as I often need those spare parts.

    Ahh, it's an older Sanwa monitor? Yeah, they're 31kHz, you'd need an upscan converter if you're putting a 15kHz board (JAMMA) in it. You'd also need a JAMMA > JVS converter, no?

    The easiest option is a JVS-PAC:

    http://jvspac.kirurg.org/

    I'm sure I've seen an IPAC used just fine in a Naomi, though.

    As he's using a PC, shouldn't he be able to get 31kHz out of it? Or does he have to convert it down to 15kHz with an arcade card, then back up again? Seems kinda pointless!

    If you had to upscale, an XRGB should do it.

    *EDIT*

    Wait, it's a Net City? Weren't they the later units with multi-sync monitors?

    It's a Net City by name, but perhaps not by nature! I know it's not the original monitor.

    I was told I'd need a convertor by Penrhos, however one way to test is to try a PC right now on another unit. Which I am setting up right now.

    :)

    Bloody hell, I wonder what Penrhos was banging on about, perhaps he misunderstood my intentions and thought I was just going to use Jamma and not MAME? It works fine... just bung that PCB I gave you and test it with a PC and it should be fine.

    Not the best PC picture quality I have ever seen, but might look better with a bit of tweaking.

    Edit* Unless of course my current monitor is dual or tri sync. Will check!

    I did output from Naomi 1 motherboard to a PC monitor ages ago using a Capcom I/O and direct from the motherboard itself and did wonder whether my PC monitor was particularly good or it was 31Khz... HOWEVER - d'oh the Naomi has a 15/31kHz dip switch!

    Yeah, the Naomi board can output in 15kHz if you flick the first dip switch I think it is, iirc.

    The later Naomis (e.g. Net City) were tri-sync, I believe, whereas most Universals were 31kHz.

    Glad to hear it works - thought it should do! I've never tried, personally, but the theory's there! ;-)

    Theory proven!

    Just for information, the Universal kits are no longer available from Sega or from Sega Shed, infact anyone I can think of. So you often find that people (me included) take a Universal and apply Net City artwork as the full art kits from Andy look better. So if ever purchasing a decent looking Naomi unit with new artwork applied then don't take it for red that the monitor is what you are expecting!

    The Monitor has Toshiba on it but the board says Nanao. I assume Toshiba were manufacturing the tubes for Nanao... not that important in the end really I guess! :shrug:

    I can't see me ever making use out of any Jamma stuff so can't see the need for an upscaler. No point in getting one for MAME, I don't really see the benefit in running soft15khz either, but maybe I could be proven wrong there.

    The Abit motherboard seems to be dead so I switched it for an Asus equivalent I had and did some early speed tests etc,

    Here I't is running a couple of CPS2 and CPS3 games...

    All running 100% no skip. They look much better in the flesh, piccies don't do it justice IMHO

    Aye good shout - see above, I already ordered one at the weekend, heh. Parris sold me an IPAC with the cab, but then It wouldn't be so easy to switch back to Naomi. (I might wanna pick up something like Guilty Gear for it at some point - and I'll still play Virtua Striker) so the JVS-PAC is perfect for that

    The IPAC may come in handy in the future tho, I may build a woody for uprights in the future and put my ghetto upright in it, hehe

    Looking great!

    Loving how you've 'tated that monitor, plus the converted SNES... HA! I have that exact same Sony monitor lurking in the attic. Great screens!

    Seems that you are all set up! I've got 3 versions of Guilty Gear 1 & 2, I recommend getting them - good fighting titles. I also have Melty Blood Act Cadenza and it's rather rubbish actually.

    Let me know how you get on with the JVS-PAC. I am tempted to do something similar with a unit in the kitchen.

    :thumbsup:

    Yeah I do like GG, had it on the PSX, DC and PS2 even the GBA in various versions.

    I've had that monitor for ages, it's superb for the Dreamcast. It had been rotting in my garage for about a year before I found a use for it. Under Defeat and Ikaruga look great on it.

    The dreamcast stick there I modded to use on my Xbox360, and added Sanwa controls, I then put the leftovers into that SNES case to use as a stick for the DC :p

    I'll post more piccies when I get the JVS-PAC hopefully by the weekend or early next week

    Nice to see those pictures! Good to know it runs fine ;-)

    That's probably one of the most hassle-free ways of making a MAME cab! Sheesh!!

    The JVS-PAC arrived yesterday from Norway, only 4 days in the post.

    [​IMG]

    Tested it out last night, pretty simply to set up, quite literally plug and play. It's already programmed to the MAME default keys, so even the Coin Mech works just as if a Naomi game was plugged in.

    Almost there, all I need to do is finish my front end really. I've been using Hyperspin, it's almost there but not quite, I don't like the way it scales artwork. Seems quite hard to find a good FE :banghead:
