Fun fact regarding bitplane: a friend of mine realized that he could use only 16 colors instead of 32, have all colors from, say, 0 to 15 be black, then clear the whole screen by zero'ing only the first bitplane (so effectively only blitting one-fifth of what would typically need to be blitted in case you wanted to clear the whole screen between two frames).
Problem is: running the Amiga in 16 colors mode (instead of 32) was faster than using that trick in 32 colors mode.
However... That trick worked on the Atari ST. It was a very fast way to clear the whole screen. But as the Atari ST only had 4 bitplanes to start with, then you'd end up with only 8 usable colors if you used that trick.
We're talking decades ago, but I'm pretty sure I remember this correctly (as in: we actually tried and timed all this on both the Amiga and the Atari ST back in the days).

Yup, what an era. At least I've got my Raspberry Pis today.
