The last sentance is wrong for SCSI addressing on the NeXT.

If the user uses /dev/rsd? as the settings for CDPlayer on the NeXT, the  
program will not work.  There *are* no device names on the NeXT of the form  
/dev/rsd? (not on Release 2.1, at least).

The referencing of partition "h" on the device is not the cause of any  
trouble.  Many people are using CDPlayer successfully despite referencing  
partition h.  I don't know the particulars of how partitions are supposed to  
work on CD-ROM players & music CD's, but the CDPlayer program seems to work  
just fine with any partition you specify.  I think the program comes with  
the reference to partition h, so that's the partition I've used for all the  
machines I have set this up on.

I've already sent the original poster an explanation of how I set CDPlayer  
up on my machine, and that seems to have helped them to get the program  
working OK.  If anyone else is having trouble with the CDPlayer application  
you can drop me a message, and I'll send a copy of that explanation.  I'm  
reluctant to post the message given that Release 3.0 is supposed to come  
with a music CD application of it's own, which should make playing CD's a  
lot easier than this CDPlayer application does.
