Neat. I fondly remember the trick on the Apple IIgs to get 3,200 colors on the screen at one time[1]. The VGC chip had a 320x200 video mode with 16 color palettes. The VGC could hold 16 palettes in memory at a time, but you could swap palettes in and out of video memory, resulting in each scan line having its own palette of 16 colors, allowing 3,200 (200x16) different colors to be displayed on the screen at once. Because it was CPU intensive you couldn't do much else, but at the time it was pretty cool.
