Hi all,
I'm new to the list and already I really need your your help.
I have a PC configured with mamewah that I want to connect to an old 19" arcade monitor.
The monitor was pulled out of a working cabinet and should be good.
I've downloaded the 15khz boot disk from omnicade and connected my homemade cable
but all I get is a yellow screen with refresh lines
I built a vga cable and used the following pinout
Pins
1- Red
2- Green
3- Blue
5- Gnd
13- -Hsync
14- -Vsync
Is my monitor bad ? if so I can I test it ?? or do I need a video amplifier

Thanks in advance
Hugues
