AMIX starts weird long blit from address zero but it never enables DMA, blit never starts. I am not sure whats the point, some kind of protection?
Does it try to set up/start that blit early-on in the boot sequence? Maybe the developer was trying to clear/initialise chip memory, but forgot to actually enable blitter DMA. And anything else which uses chip RAM clears it using the CPU anyway, so the problem was never noticed???
