Building a VGA Display Circuit with Logic Chips
Ben Eater · Tutorial · YouTube title: The world's worst video card?
Why it's here
HN recommends it as a clear, from-scratch look at how video hardware works, understandable with just basic logic knowledge.
What it covers
Ben Eater explains how VGA signals work and builds a breadboard circuit that produces correct sync timing so a monitor recognizes the signal. He then builds toward displaying an image from simple logic chips.
