Here are a few pictures that I have taken for you to better understand what I am working with.
The only board that gets any response when I boot it up, even though all the boards I used were tested and working on someone elses machine
This video adapter is from ( http://www.jammaboards.com/store/cga/ega/yuv-to-vga-converter-pcb-gbs-8220/prod_291.html ) and connects to computer monitors.
I also have a RGBS CGA/EGA to TV and Video Composite converter that I cannot get working ( http://cgi.ebay.com/ws/eBayISAPI.dl...z7cqzgk%3D&viewitem=&sspagename=STRK:MEWAX:IT ) I have used it with two different televisions with the same outcome: a white screen or flickering white things moving around the screen with no image present.
Both of them power up, the first one even boots and lets me navigate menus, so I think it has something to do with either getting video to the adapter or from the adapter to the monitors / tvs.
Harness also from JammaBoards
Wiring:
I even bought a separate 5v power supply for the video adapters because I wasn't sure if it was getting enough power from the power supply while it was powering the boards. (yeah, I am desperate).
Does anyone have any ideas? Any help is greatly appreciated, I just don't know what else to try.
