My old TRS-80 also did "graphics" like this, with 64 2×3 cells. That was
even how it did it when you were setting individual blocks. The
smallest "pixel" you could control in graphics was one of these ⅙ths of
a character cell, and wouldn't you know it? As soon as you set one in a
cell occupied by some other character, the other character would disappear.
Not positive these count as plain text, but there's a decent argument
for it.
