First moving video output from my breadboard TTL color computer. Again, the test image is just uninitialised SRAM garbage with some lines drawn over it. Line 60 to 90 are scrolling 1 pixel per frame.

The scrolling looks a bit jumpy in the recording, but that is just the mismatch between the camera and monitor frequencies. In real life it is stable and smooth.
