I think I know the demo you're alluding to there and, unfortunately for the purpose of my search, the older 6809 demo you have in mind involved hundreds of balls: >A year earlier, I had written a fast "ball bouncing" routine, using custom, >16x16 pixel graphics >routines, that could animate hundreds of balls >simultaneously, which was a fun way to show >off >the Mac's raw graphical >horsepower.

The intro screen (which claimed that the Mac needed a couple minutes of processing time before it could start to run the demo) mentioned that the demo had originally run on the Macintosh XL. That intro screen and the fact that I ran it off a floppy disk on a Mac Plus are about all I remember about the demo a quarter-century later.
