Just purchased a cabinet with the 31" monitor still in it. The cab has a Sega Virtual Tennis picture on it, but nothing else. I can't determine the make of the monitor either. The folks that sold me the cab explained that the monitor did not have the required panel (below the tube) to run the monitor. Damn. Does have another small board attached with some monitor inputs connected and a fuse on it.
Here is my question; can I run the monitor directly from the pc using a vga to arcade monitor connection like the one found here: http://dragonsden.emuunlim.com/ddvgatutl.htm
From the research I have done, I think the rest of the wiring would go to a jpac for controls and lighting. Still trying to figure this out, but I am stuck on the monitor question. Thanks in advance for any help on this problem.

You could always try the ArcadeVGA (http://ultimarc.com/avgainf.html").

See if the monitor is 15Khz, 24Khz, or 31Khz. I think that Virtua Tennis may be selectable output resolution.
If the monitor is 15Khz, I would go with the ArcadeVGA, and the appropriate wiring. The reason being, is that you can easily fry a monitor sending a 31Khz (VGA) or even higher (SVGA) signal to it. The ArcadeVGA is custom designed for 15Khz Out.
If it is 31Khz, you can probably connect it to the card directly.
If it is 24Khz, you will need to use AdvanceMAME, and configure it to output EGA res. In addition, you will need stretch for most games.

It sounds to me like your monitor is missing the chassis (mainboard), and thus isn't going to be hooked up to much of anything.
A game usually ends up without a chassis for one of two reasons.
The tube went bad, and they robbed the chassis to repair another game with a good tube.
They took the chassis out in order to repair it, but never put it back in.
Easy way to tell if you have a chassis in there is this. Somewhere there should be a large plastic cylinder (smaller than a soda can, but bigger than a roll of quarters) with a couple of knobs on it, and a red wire running to the suction cup on the tube.
If you can't find that part then you don't have a flyback, and if you don't have a flyback then you don't have a chassis (if just the flyback was missing it would be obvious where it was removed from).
There should also be a small square circuit board that is attached directly to the back of the tube (the neckboard) with several sets of wires that run to the chassis.
Finally, the monitor probably also has a remote control board. It sounds to me like the only thing yours has is the remote.
Basically, if you still don't know what I am talking about. Your monitor is like a car with no engine in it. It isn't going to go, no matter what kind of gas you put into it.

Thanks for the good information. Here is a link to some pictures of the cabinet: http://f.dominodeveloper.net/winetracker/Gallery.nsf/d073a1c749c0fee085256b650012eecd/08485d434801521988256dbb005cf0e9!OpenDocument
Any ideas on where to start to make this thing run again?

Buy a new monitor, I'm sure the tube must be bad since you are missing too many parts.
