ArcadeVGA configuration issue - unknown Wells-Gardner monitor

[NineInchNall]

Okay, so I'm attempting to resurrect a system (that someone else built) in which the original mobo went bzzzzzt. The system originally used an AGP ArcadeVGA, but since that specification no longer really exists, I bought a shiny new ArcadeVGA 3000 and shiny new mobo, proc, and all the rest. Okay, so here's where the difficulty comes in:

I don't know how to configure the AVGA/JPAC combo to work with the monitor. It's a 33" Wells-Gardner monitor, one which I know for a fact can handle low res (eg., 256x256) and higher res (eg., 800x600). Yes, I said 800x600. Anyway, it's not a D9200, since that has a nice VGA port on the back and a convenient OSD for adjusting stuff. No, I'd have to adjust some potentiometers in back to change anything not on the remote PCB (which handles brightness, contrast, h size, h pos, v size, & v pos).

I tried looking on the WG site, but the only 33" monitor listed there is the D9200 - which, again, this doesn't appear to be. I also tried using their Serial# lookup, but apparently, my unit's a secret agent.

With the JPAC's 15 and 31 kHz jumpers set, the best I can get through the AVGA card is a divided image (as in the first attachment). No other jumper configuration seems to work. Like, at all. The funny thing is that the LCD monitor I have hooked to the DVI port works flawlessly, displaying all the wonderful low resolutions I bought the card for.

Oddly, however, I can get a rather nice picture out of Soft15 and an old Radeon HD4800 I had lying around. With the JPAC's jumpers on 15 and 31 or just on 15, 640x480 shines through all pretty like. 800x600 displays, but it can't get v-sync, so it just rolls and rolls and rolls. And that through a DVI-VGA adapter, no less. I'd make do with that, but Soft15 doesn't give as many res options as the AVGA card does, and were it not for the fact that I know this screen can display 800x600.

So I come to you, oh wise and learned members of this forum. What am I doing wrong with the AVGA that is preventing it from sending the proper signal to the arcade monitor? I mean, it doesn't appear to be a JPAC issue, since the display works fine with Soft15.

Halp!

it's a U3000/K7600. there wasn't many machines that used it. (Ultimate Mortal Kombat and Primal Rage) which is why you aren't going to find any real info on it.

it's still a 15k monitor. You aren't going to get much resolution out of it. it definitely wont do 800x600 without some kind of video card mumbo jumbo scan conversion or a hardware scan converter. (least that's what I think. i don't know how you know it does 800x600)

check out http://www.ultimarc.com/ site or give Andy a PM and see if he can get you configured.

Thanks for the ID help. I'll see if Andy can help.

Actually it MIGHT be possible to get close to 800x600 interlaced on a 15K monitor with a low refresh like 50 Hertz. Of course this also depends on how narrow the horizontal frequency range of your monitor is. I know most can't go much above 640x480i though. This would be worthless for games but ok for a desktop.

When you have the jpac's 15khz jumper set, any resolution over 15khz will be halved. I don't think you are supposed to have both 15 and 31khz jumpers at the same time.
