I remember seeing a Mandelbrot program for the C64 where half the image was computed on the floppy drive because it's basically the same computer as the main C64. I think it had a 6502 instead of a 6510 and different memory.
I believe the Apple II floppy drive was "dumb", that is, controlled by the 6502 of the Apple II, so the machine couldn't do anything/much while loading/saving data. But the C64 + floppy drive was essentially a two-node distributed system.
