I found versions at http://www.sco.com/skunkware/ in the Development Tools section.

   After you pkgadd it, there's a good sco_notes.txt file I recall,
   which contains the method to burn a cd.  It's also here:

       http://www.sco.com/skunkware/cdrecord/SCO-NOTES.html

I found the latest version, off the net and compiled it because burning cd's is tricky. I'd like to limit the environmental disaster of coasters, if you know what I mean.

     The file sco_notes.txt contains the method to burn a cd.
   That's somewhere on SCO's website and distilled here.

   You'll want to run the following command as root, once you have
   cdtools installed:

       cdrecord -scanbus

   That let me see that my scsibus,target,lun for my cdrw was 0,4,0.
       0,4,0     4) 'PLEXTOR  ' 'CDR       PX820T' '1.08' Removable CD-ROM

   1) You don't need an /etc/default/cdrecord file.  It's doesn't
      work right anyway.

   2) Let's say you downloaded the SCO (Caldera) Workstation 3.1 iso image.
      Cd to the directory it's in.

   3) cdrecord -v dev=0,4,0 speed=8 workstation-3.1.iso
        - or -
      cdrecord -v dev=0,4,0 speed=8 -dao workstation-3.1.iso

   4) mount -r -F cdfs /dev/cdrom/cdrom1 /mnt

  Here's how to create your own iso image of the files in a directory
  and how to burn it in DAO mode, as an ISO9660 Data Mode 1 disc, without
  Joliet nor RockRidge extensions:

   1) Copy all the files that you want to a temporary directory
      called /home/tmp/cdi and arrange the files the way you want them
      on the final cdr that you are going to burn.
   2) # cd /home/tmp/cdi
   3) # mkisofs -L -l -v -r -V mydisc -o /home/tmp/out.img .
   4) # cdrecord -v dev=0,4,0 speed=8 -dao /home/tmp/out.img
   5) # mount -r -F cdfs /dev/cdrom/cdrom1 /mnt

   That worked well for me.

   (1) The default file doesn't work.  If you make a valid one and only
   use it rather than specifying a dev=, then you'll burn coasters.
   (2) is self-explanatory.  
   (3) cdrecord needs to run as root, or else you need to set up the 
   SUID and SGID and permissions stuff.  
   (4) Change to the correct directory.  
   (5) It is necessary to make an ISO filesystem image of all your files, 
   and the flags are important, and so is the '.' which is just like the  
   relative pathname notation in cpio.  I got the args from the 
   SCO_NOTES.html file included in the archive. The -V mydisc is what 
   labels the cdrom "MYDISC".  
   (6)  Burn the cd now.  
   (7)  I'd eject, then insert and mount the cd.

   If you want to do a simulated burn, then add the -dummy flag to the
   cdrecord command line.
