I'm trying to add an ISA VGA video card to my Partner 1. There is a spare slot on the board so I just added it there. When I power up neither monitor works. I'd pull the EGA board but there are a couple of ribbon cables besides the CRT hooked up to it. I'm not sure what they are for, one goes to the spindle, I'm not sure about the other and there are a couple wires hooked to another!
Can anyone tell me how to get the new cars working?

Thanks!
