Original Macs actually had 1 bit graphics. “Gray” was done by clever placement of the black and white dots in different patterns to look gray at a distance.

A great visual intro to dithering here [1] and a specific filter based on Bill Atkinson’s algorithm for the original Mac here [2]

Wow, ages ago, one afternoon, I played around with "page swapping" on the Mac Plus. You could cordon off a chunk of RAM to act as a second screen buffer, render to it, and then toggle the screen buffer during screen retrace to get a very fast (60hz, er 30hz, I guess) "flip animation".

As I recall from my brief experiment, you could get a pseudo 50% gray where the corresponding pixels on the two buffers were opposites (one buffer with a black pixel, the other with white).
