That being said, you'd have to resort to driving
the 6522s yourself to
manipulate the bitstream directly -- very low-level, and of course with the
small amount of RAM in the 1541 this would require impressively tight code.
But it is, theoretically, possible at least on some level, even if it's
merely decoding the bytes and handing them off to the C64 for processing
(putting the "DOS" in the 64).
Programming 6522's is not that difficult (I've done it before and I'm
working on a project right now that uses one). Isn't there 4K of RAM
inside each 1541? That's a goodly amount of RAM for disk drivers.
