  Wow that turned out very clean. This person must be rather experienced though. I appreciate that they laid out the design process there.

  I read that as discreet logic and got nostalgic for SGI and the days of 90s vfx.

    Nice work :) What's the clock rate?
    • ynoxinul 4y ago
      Currently around 3.5 MHz.

        That's a lot more than I thought.

          If you're judging from the calculator video, that time it was much slower. The current speed can be seen in my post about the video card (https://imihajlov.tk/blog/posts/vga/ https://imihajlov.tk/blog/posts/vga/).

  James Sharman's build is nuts. He has been at it for several years. https://www.youtube.com/watch?v=3iHag4k4yEg&list=PLFhc0MFC8MiCDOh3cGFji3qQfXziB9yOw https://www.youtube.com/watch?v=3iHag4k4yEg&list=PLFhc0MFC8M... Usagi Electric is taking it all the way with a vacuum tube build. https://www.youtube.com/watch?v=y149hLe1zYo&list=PLnw98JPyObn0v-98gRV9PfzAQONTKxql3 https://www.youtube.com/watch?v=y149hLe1zYo&list=PLnw98JPyOb...
