It didn't have braille characters, but my old Kaypro 2x had a blocky, character oriented form of pixel graphics. (The rather fat pixels needed to be rolled together into a "character" that was outputted, as best as I recall.

It was enough to be able to display some chunky looking but workable fractal images. Somewhat similar to the time I generated the like on a Dec something or other and printed them on the available dot matrix printer.

Fun, if much simpler, times.
