    Broken Apple IIe - garbage screen

    Hi, my first post. I picked up this apple IIe (looks like a PAL version) in a garage sale, but it won't boot. It won't beep. The drive won't respond. There is a light on the motherboard that goes on... but the video display is all blocky garbage. I cleaned up the motherboard, and looked at...
