Just make sure it's a SCSI CD-ROM drive and you're in business. A SCSI
device is a SCSI device (my guess is the ribbon connector is even
identical). However, taping into your dock's audio is a different story.

Your best bet is to run audio cables out of the dock from the CD player to
an external source so that finally (unless you have an audio Nubus card)
you can have stereo with your Duo! To keep everything internal, however, I
would still run the CD audio cables out of the box and then combine them
into a mono feed (Radio Shack makes just such a cable) which you then plug
back into your dock's sound-in port. Please note that by doing this you are
in effect creating a non-linear mix which has the nasty side effect of
allowing voltages to cross & back-flow and potentially damage your
line-level amp on the CD-ROM. Because the voltages are so low, the novice
user probably won't notice for many years, but it ultimately results in
distortion as the amp slowly fries. The proper way to do this would be to
run the stereo signal through unidirectional resistors first before
combining the signals (like if you ran it through a mixer), but I've never
seen these outside of a mixer so you might have to build your own. Keep in
mind, that this is the professional way to do this. People do it all the
time and never notice a loss in quality. Heck Radio Shack even sells
adapters for this purpose, even though the engineers should know better
(for years you simply reversed "splitters" to do it and now they also
re=package them as "combiners" ... oh, well anything to make a buck).

While we're on the subject, anybody try to change the direction of the
floppy drive so that it points out the front of the machine? I'm still
trying to get my HD-20 to logic board floppy connector pinouts so that I
can make a special cable so as to use the Duo's external floppy drive with
the Dock and be able to place it wherever I need it (my Dock is in an
enclosure which makes accessing the side difficult).
