The various stereo sound cards like the SB Pro do have CD-ROM
connectors.  The SB Pro has a custom funky connector and a special
CD-ROM drive to go with it.  They've gotten enough heat over this that
they're doing what all their competitors are already doing: a real SCSI
port and a real SCSI CD-ROM.  These cards don't support booting hard
disks off their SCSI ports, though; I'll be impressed if any of these
vendors support two devices on a SCSI chain.

Another thing: a researcher at CNMAT (UC Berkeley's computer music
foundation) said that the best way to do interactive multimedia off a
CD-ROM is to have two copies of the CD in two drives.  This is much
more economical than caching data from the ROM on a hard disk.  Does
your CDROM driver support multiple drives?

Also:  on ftp.apple.com you'll find a pair of ISO 9660 programs that
build and check 9660-format file systems.  I forget the names
of the programs.
