The classic Apple bitmap font "Chicago" tries to avoid aliasing by sticking to 90° and 45° angles in letters like W, M and K.
However, this idea is much older than that. This pixel font is from a French embroidery book printed in 1527.
The previous two pages sample a blackletter font. Blackletter is by itself more orthogonal and angular than Antiqua, so the idea works much better there.
