I'm posting what my solution was to my CD problem because some people
were having similar problems:

1. The above is correct.  Nextstop doesn't understand audio cd's because
it's looking for file systems to mount up and audio cd's aren't FS's.

2. The device number on CDPlayer0.8 (CDaudio) refers to the order in
which the CD-ROM sits on the scsi bus.  In my case, I have 100M
and 660M hardrives sitting on the bus inside the cube, plus the
floppy drive.  So I thought that my CD-ROM scsi id and the logical
numbers matched at 4.  But this is not so.  I'm not sure exactly
how the order goes, but from trial and error it turns out my CD-ROM
is logical device 2.  Go figure.  So, if all else fails, I guess
you can try all logical device numbers to see which order your
CD-ROM is.

3. A final note on installing CDPlayer or CDaudio: follow the 
instructions as to the setuid things.  Plus, make sure that both
programs are chown'ed to root.  I had them as operator, and I think
this may be the reason why when I pressed Load, I never got the 
prompt panel.

So those were all the things that I did to finally get the thing
going.  Anyway, it sounds great!  And as usual, I have to thank
the many people on c.s.n.m. for helping me out.  This is by far
the best newsgroup for getting problems fix.  Thanks for the patience
and the help!
