Hey all. Qbert recently started acting up, with weird color issues and flashing background. A little research advised the most likely candidate would be the filter board. Taking a look, it seems as though the filter board has been burnt and jury-rigged all to hades.

I've ordered a replacement from ArcadeShop, but does anyone have any documentation that I can use to verify what wires are supposed to go where?

Thanks,
Rich

Maybe the manual?

this. there is a whole legend inside there. but given it's a Gottlieb game I think you need to own an actual manual, you might not be able to find a PDF online.

you could've just bought new header pins and the parts to replace the molex plugs, probably saved yourself some money, and notch a win for yourself.

for anyone else with a Gottlieb/Mylstar game with various issues regarding the filter board, I strongly encourage you resolder all the header pins and replace anything I mentioned above if it's burned up.
