Wow. That is one loaded system.

It sounds like you're running out of slots. My ProDOS reference manual has
no information on the way ProDOS handles remapping drives. Others should be
able to correct me if I'm wrong, I'm only going by memory here :) ProDOS can
only handle two volumes per slot, any more and it will remap them to slots 1
and 2 (as happens with you AppleTalk drives from slot 7). What happens when
you have the last usable slot 1 set to 'your card' for AppleTalk in a ROM 1
GS? Does this appear to ProDOS as a disk drive controller, in which case
presumably it won't try to remap any volumes there?
