You need to compile a kernel with 'options CD9660' in the 
machine-specific file in '/usr/src/sys/arch/pmax/conf'. The
GENERIC kernel doesn't have this option in it.

Then use:

	mount -r -t cd9660 /dev/rz4a /cdrom

or similar to mount the CD.

This works fine for me for ISO 9660 CD-ROMs, and I regularly use
Mosaic to browse these on my 3MIN. I think the man page says that
'mount_cd9660' doesn't support High Sierra CDs, but I haven't seen
one of those in years... I don't have a executable 'mount_cdrom'
in my '/sbin' directory for 1.2.

If the CD contained (for example), some Unix filesystem instead,
you probably wouldn't have to do this, but could mount it directly
as long as it was a directly supported type.
