In the past few weeks, I acquired an Apple II Plus that seems to have a graphics error. Whenever I attempt to boot the computer, vertical lines appear instead of the normal startup screen. I don't know if a chip is fried or what. I've added a high resolution image of the motherboard below for reference. Any help is appreciated!
P.S. - I should add that I'm an amateur when it comes to pre-mac era Apple machines and this is my first Apple II.
