I don't recall either. For those that don't
know, the Amiga doesn't have
a traditional FDC chip - it uses a massive shift register in the sound chip
to clock pre-encoded data on and off the disk, and uses logic functions of
the graphics chip to convert entire tracks to and from MFM encoding. That's
how they get 11 sectors/track - the intersector gaps are tiny compared to
what a sector-oriented controller needs.
So what happens if you try to do disk access while displaying animations?
