Hello, I Recently got a new-to-me Apple //c but upon powering it on it displays a garble of flashing characters. I've already re-seated the IOU, MMU, CPU and MON, as well as the Power Supply and Character Generator. I've attached pictures of the monitor as well as the components. Everything is in really good condition and I've confirmed that the external Power Supply and Monitor are working on another system. Looking for advice before proceding.
