In this video I repair
In this video I repair a Mac 512k motherboard with an unknown RAM expansion card on it. In part 1, we looked at two Mac motherboards with unusual RAM expansion cards. The Mac 128k motherboard worked, but I left the Mac 512k motherboard for another video. This is that video! Figuring out what was causing this motherboard to not boot and display video issues required me to study schematics and try to understand the architecture of these early Mac machines, and it paid off!

Part 2: This part!
