Making the RGB signal stronger?

As far as getting the connector, the adaptor for Guncon for later PSXs has it, just cut off the end that goes into the PSX. (it has a pass-through port)

If you're looking for the pinout of PSX RGB, Games X has it.

Still waiting to hear how M Pro managed to get the card to output 15kHz...

Powerstrip most probably.
Be advised though, not all cards will support it

This might be of some use . Found it on the gamex boards.

Hmm. Specially designed for 15hz. based on a Radeon 7000 chispet so performance should at least be adequate for most things, even if not particularly stunning (though probably will be compared to TVout).

Have a good look arround that ultimarc site. Some of their controller boards could prove a fantastic boon to someone wanting to make their own iDrive type controller. Using an Opti-pac for the top spinnerknob, with button on top (or whole top as a pushable button, and an I-pac for the joystick portion it should be fairly simple, you would just need some old cabinets to gut for the parts.

they even do their own arcade cab sticks and buttons, so you would only need to locate the spinner.

Silly Questions, but
on the VGA connector
Ground 5
Ground 10
Red Ground 6
Green Ground 7
Blue ground 8
id0 (ground) 11

Did you connect all these grounds together, and connect to pin 1 on the ps screen, or did you split them and connect to pin 1 and 3?

Or did you just connect 5 and 10 (VGA) to 1 and 3 (PS), and 6,7,8 (VGA) to 8 (PS Video ground).

Or did you just put pin 5->1 and leave it at that.

next. You said you put a resistor between pin 11 red (PS), and the syncs on 6. Would it be better to sync on green pin 12 (PS) like a PC monitor does?

Again, as I said some stupid questions.

I have of those cards, they're quite good. Nothing quite like playing Unreal Tournament on a 15 year-old arcade monitor. I'm still curious how specifically he got a normal card to display at 15kHz, one of the reasons that I have an ArcadeVGA is becuase it's normally hard to get a card to display windows at 15kHz.

If you're looking for more arcade stuff that could be used with a carputer, check out Arcadecontrols.com , lots of links to companies making various parts, including spinners. How to make your own spinners with parts from a mouse and stuff from Home Depot, and other DIY stuff.

Tom, I'm pretty sure that with A Matrox card, and some of the TNT ones, plus Powerstrip, or some other detailed display settings prog (like the ones that actually allow you to change chip registers), you can change the synch frequency etc as well.

Thanks for the stuff about arcadecontrols.com, shall give that good look, because I want to build an iDrive type controller, as well as having a touchscreen.

Ok here is the layout I used to get my LCD to work

As you can see the parts cost pennies and the layout is quite simple

Then after you make the cable install the latest version of Powerstrip. "I have PowerStrip 3.30 Build 366"

Load up Powerstrip and go to Display Profiles/Configure

then from there go to Advanced Timing options

From here click on custom resolutions

Now scroll down to you get to 640x480i (Arcade) and select it
Now this will tell you if your card will work with this setting.

If you look as setting you can see interlaced ticked, if your card has this grayed out then your out of luck and can’t do this.

But if it’s ticked after you click on 640x480i (Arcade) your good to go!
Click on add new resolution

now if all gone well your main monitor will go off as the sync will be to low for an ordinary monitor. If this is the case swap to your LCD ASAP! As you only get 10 secs to do this or your have to add the resolution again.

Then after you have your LCD hooked up you can adjust the position, but keep an eye on the pixel clock at the top and keep it at roughly 13.678 to 14mhz and you should be fine

that’s what I did to get my LCD working.

I have tested it with 3 TNT cards a geforce 2mx and a Geforce 4 TI and a Matrox Mystique and all work

what I couldn’t get to work was any voodoo cards from voodoo3 to 5

I tell you its amazing how hard it is to get a good pic of an LCD

You sir are a gentleman. And will have made somebody happy.

I'm now trolling round my friends, to see if anyone has a broken PSone that they don't want, to see if I can buy a damaged main board from them to get a Multi AVout connector. then I can solder it to the VGA cable, and get a removable screen option.

That is the layout out I was planning, and I see that you only used one of the VGA ground wires. Cool.

Over in the UK, the cheapest chain store VGA cable I've seen is £15 (about 18USD approx), probably cheaper if I hunt through smaller shops, but big retail park/chain stores ones aren't cheap/

What I did was pop down to the local dump and got an old monitor for a couple of pounds then cut the cable of that.

Nice and cheep

That's really interesting M Pro, I did not know the newer version of Power Strip had a built-in arcade monitor mode now(previously you had to figure out the dot-clock, refresh rate, etc. by yourself).

You know, I had this crazy idea that you were in the states. Where abouts in the UK are you?
