Virtua Striker Arcade Machine Help

[fogisgod]

Afternoon
I have recently bought the Sega Virtua Striker Arcade machine and looking to convert this into a Mame Cab. I have all the software installed on my pc, bought the I-PAC with all new sticks and buttons including wiring.
The only thing im confused about is the monitor, the monitor inside this cabinet is a Mitsibushi A63JHF81X CRT25, Medium Resolution.
I been asking various people on how to connect this monitor and i have been suggested this.

Would this simply mean that i take the wires of the current Jamma board, connect them to this VGA lead and plug into the graphics card on my PC, the graphics card i am running is a ATI Radeon 9550.

Please help as this is the only thing i am unsure about.

Many thanks

Does anbody know if the monitor for this Virtua Striker machine is 15khz, 25khz or 31khz

Many thanks

Virtua Striker would have a Medium resolution monitor (25khz)

also that Mitsubishi part number you listed may just be the tube part number

Hi. Did you manage to get this working? I have the same set up and connected the monitor to my PC using a breakout cable but all I get is a flickered screen.  I don't have an arcade VGA which I think I must now buy to resolve this?

hello and welcome,
 yes you will need an arcade vga in order to output properly to the medium res monitor

Thanks for your help. I'll buy one of these Arcade cards.  Have seen them for £57 +vat from Gremlin or I could buy an ATI 4000 (or less) and software mod it to work - as is my understanding.

One final question if you know.  The breakout cable has 6 inputs : R G B Vs Hs Gr.  Only 5 cables from the monitor though : R G B and then twisted Wh & Blue plus a plain white.  I'm pretty sure the plain white is the earth but that then leaves a single Wh & Blue cable for both the Vs and Hs connector.  Anyone know which to plug it into?  Also IS the plain white the ground cable?

Jamma boards use a composite sync.
So there is only one sync line.
  I know some standards may be different for your region (I'm in the us) but here is a good article from Bob Roberts that explains sync.

Also note that when you go to hook up your monitor to the PC, there's a chance that the image may be way too dark.
If this is the case, you may need a video amp. Ultimarc has these.

Thanks very much for your help...

I'm still struggling to get this Nanao monitor connected to my PC using a breakout cable.  I've attached a picture of the way it is currently connected which doesn't work.  However I think I know what the problems are and I wanted to see if someone could confirm this.

First, I've simply jammed the soft cable ends into each connector - I think this type of connector needs those hard pins?

Second, there are only 5 cables coming from the monitor (in the picture these come from the bottom) but 6 inputs on the breakout cable.  I've tried swapping the Blue/White cable from HSYNC to VSYNC but it makes no difference and doesn't work.

So my solution is going to be to cut the connector off the breakout cable, twist the Green/white and Blue/white cables together (those 2 cables going into the top of VSYNC & HSYNC on the pic) and use a 5x terminal block to connect it all together as follows:

MONITOR > BREAKOUT

R > Br
G > R
Blu > O
W > 5 ground cables
Blu/W twisted together with G/W > Blu/W

A big assumption here is that the White cable from the arcade monitor is in fact the ground.

I'd appreciate any advice here please...

How exactly is it not working?
Is there no picture, is it real dark or is it not sync'd

Also what Nanao monitor is it? I've only ever worked on one model of them but it was capable of either standard or medium resolution.

You definitely do not wanna just have those wires stuffed in there.

You may need to have the sync going to both the horizontal and vertical sync on the monitor.

There's just no picture at all - it's not dark or not sync'd.  Just white 'fuzzy' screen.

I don't know what the model is but it is a med resolution, been told that by a couple of different people.

I take on board what you're saying about the wires - knew that wasn't right.  I'll connect them to a terminal block.

As for the sync wires, there's 2 coming from the VGA lead and only one on the monitor (I think).  The white wire from the monitor is the earth am I right?  If so I can twist the H & V from the VGA Cable together and connect them to that blue/white wire I think?

It sounds like you may not have the right video ground.
Can you get pics of the connections at the monitor.

I've sorted the connections out now - purchased an Arcade Monitor Video Amp which has 5 connectors that marry up to the monitor cables.

Looking at the screen now though there seems to be a tuning issue though (have attached a picture).  This is the BEST I can seem to get the screen to when using the tuners.  You can definitely make out the windows icons so I know something is coming through but it's a long way from being tuned in.

The graphics card is an ARCADE VGA 3000 purchased from Gremiln and I've installed the correct win 7 drivers.

I read somewhere that the Nanao monitor can be 'switched' to Low Res - is that something worth trying?  If so does anyone know how to do it?

yes from a quick view, it looks like thats the issue.  I know the nanaos I have worked on can be set for standard or medium.
