I've been working on getting some of Hellmood's 256B x86 Memories
demo going on Apple II. A lot of it is possible, though of course
much, much, larger especially things that multiply or divide.

Anyway here's the scrolling checkerboard in 42 bytes if you want to
try it. You can get the code a bit smaller if you're not
particular about the colors.
