wg 7900 MAME

[poser]

I have a Wells Gardner 7905 monitor in my arcade cabinet. We are having difficulty with setting the video mode on the linux pc we have installed in the cabinet.

Does anybody know the specs for this monitor or where I can find them?
Apparently we need  ALL the specs for the monitor since we are making our own driver.

So far the best we can do is a clear picture that is split in the middle and wrapped around the edge of the monitor.

ANY help at all would be MOST appreciated.
Thanks in advance,

Brandon

You're better off to try a MAME forum than this one, but the 'best result' you've obtained so far indicates a 15kHz monitor receiving a 31kHz signal, ie a high res picture on a low-res monitor.
