Since this subject is of more general interest, I'm posting this for
general consumption.
Anyhow, CDplayer0.8 works quite nicely on my 'station (mono slab, 8Mb
RAM, 105 Mb hard drive, NeXT CD-ROM drive). The trick is that you have to
start CDPlayer *before* you insert the audio CD in the drive.
Audio CD's aren't _directly_ readable (has to do with some copyright
issues), but the player software works by sending SCSI commands to the
drive (from CDPlayer0.8 README):
===============================================================================
When a track is requested for playing, cdplayer will send a request to
the CD SCSI controller to begin audio play, and then exit. If the request
fails, an error message will be produced. Otherwise, the specified track will
play until completion or another request is made (i.e. cdplayer is used to play
another track, pause, etc.)!
===============================================================================
It does make a neat diversion until NS 3.0 arrives :-)!
