It doesn't.
The Duo Disk has one 25 pin connector. As earlier mentioned, similar to that of the Apple ///. IT can be daisy chained in that it is the last device. It lends itself to this by the very fact that there is only one connector. Connecting the DuoDisk to the back of a prior 5.25" drive usually nets you it's first drive working when drive #2 in the chain is accessed.Would you have the use of both the drives in the duodrive if it was chained after another drive? Anyone? I'd guess not.
Nope, just the first drive, since "drive 2 select/enable" would never be asserted (assuming you mean chained after a 5.25" drive). -michael New, faster SUDOKU v2.0 solver for Apple II's!
