This was written in 4 days at Kansasfest as part of the Hackfest. It uses an unusual 40x96 by 15 color Lo-res mode on the Apple II by switching between graphics page1 and page2 every two scanlines (typically you only get 40x48 in Apple II lowres mode).

The Apple II has no standard way to detect hblank or vblank, so the demo uses the "floating bus" to determine beam position on the screen at the start, and everything else (scrolling, rasterbars, mockingboard music) is done by pure cycle counting.

for the platform. Not big fan of Apple, but it's pity that there are too few prods for this platform.
