I picked up a Black Knight 1980 a few weeks ago.. and it was working fine for about a week...then it stopped starting.. I'm a newbie when it comes to repairs. So, I read about the Williams system 7 and how to upgrade the board here. There are areas where the board is burned. Especially, the area in the bottom right with the resistors. I ordered replacement transistors, resistors and connectors. But, I'm not sure if the board is ok. After taking all of the burned resistors off and cleaning it with alcohol, some of the metal on the board has burned off. Any opinions on this? IMG_0106.JPGIMG_0110.JPG IMG_0105-682.JPG
