There have probably been enough replies on the CD, so I thought it might be helpful to mention some other boot options :)
If you have a SCSI disk and controller in another device you can dd an installed system into the disk. Last I checked qemu sparc worked quite well to install onto an image (or any number of people on the list could provide a suitable disk image)
Sparcs also netboot well, you just need rarpd and tftpd to get a the bootloader across, after which bootp and nfsd (or bootparamd if you are very old school :). Even if you get the CD working it's nice to keep a netboot setup around.
Alternatively if the floppy drive has not expired you can boot from that...
Once you have an OS loaded it gives another way to test the CD
