Looks related to the 6845 variant, but I imagine this
6847 board has more
graphical capability.
For what it's worth, the 6847 is intended for use with NTSC TV sets.
Character display mode is only 32x16 making 512 characters per screen.
Characters are displayed in a 5x7 pixel format. If you use the internal
ROM, you get uppercase only. For a TV, this is fine, but is otherwise
pretty limiting.
