- PaulHoule 4y agoIt's not that hard to build a display controller but it's problematic for projects like https://www.youtube.com/watch?v=LU5989eVRZs https://www.youtube.com/watch?v=LU5989eVRZs because that kind of system competes with Raspberry Pi which puts a lot of downward pressure on what is an "acceptable" price. Real 8-bitters used custom chips for their display controllers, but if you don't use custom chips you need a few handfuls of logic chips and you wind up with something about as expensive as the video card linked to above. To justify a custom chip you need big volume. You can make a display controller from an FPGA or Microcontroller, it's probably cheaper than one made from small chips, but still not cheap enough... And there's something absurd about using a much more powerful part than the CPU to run the display.
- sitkack 4y agoI just found out about that a couple hours ago from this person's implementation, https://www.youtube.com/watch?v=ZoZWe-e_1YA https://www.youtube.com/watch?v=ZoZWe-e_1YA What a great project!
