Yes, I think that one was something along the lines of rapidly selecting 
different drives whilst issuing read commands - the result is that the FDC 
chip passes through data that it would normally hide from the user (because on 
a regular PC-type disk format it would be low level data marks that it 
considers not important to a user, but for Amiga disks it's actually 
information required to decode the disk data)
