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.
